How to take care of an orphan
The following information is for those with a sanctuary permit. Keeping a wild animal in captivity without a permit issued by the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (formerly the Ministère de la Faune, des Forêts et des Parcs) is illegal and punishable by fine. A native animal living in a citizen’s home without a permit could be seized and euthanized.
The information provided and the uses of the medications listed in this section are based on our personal experience of what works best for us at this time or have been recommended by veterinarians or other shelters or sanctuaries with experience with wildlife. We strongly recommend that you consult with your veterinarian when making decisions about medications, dosages and techniques used to treat a wild animal. The authors assume no responsibility and give no guarantee for the results obtained by following these dosages, information or uses. We cannot be held responsible for damages resulting from misinterpretation or error on the part of the publication or the user.
If you wish to open your own shelter, please consult our page on how to open your own wildlife rehabilitation shelter in Quebec.
The first contact is usually made by telephone with the person who found the orphan. Telephone counseling can solve problems, save lives, and prevent the kidnapping of “baby wildlife.
First get the person’s name, address and phone number, then ask the following questions:
- Where is the animal now? Is it safe?
- When was the animal found?
- Where was the animal found?
- Did he offer food? Did the animal eat any food? If so, what and how much?
- Who manipulated him? What kind of contacts? What was the extent of the contact (minutes, days)?
- Were gloves worn or other protection used to avoid direct contact?
Ask if it is possible that the animal has suffered a cat attack. If this is the case, the animal must be treated with antibiotics because cats have extremely toxic bacteria in their saliva.
Often, a citizen will call you or a veterinarian’s office for information about raising wild babies. Please do not provide information that would make a caller feel qualified to care for the animal. If a caller has a wild animal in their possession, ask them to bring the animal to you immediately or to another qualified facility.
If the person seems determined to care for a feral baby, your job is to explain why this is unrealistic, dangerous, and illegal.
- A baby wild animal that is now soft and cuddly will grow into an adult wild animal with strong defense and survival instincts. As wild animals mature sexually, their hormones give them a strong impulse to procreate.
- When frustrated, captive animals usually become aggressive.
- A wild animal in captivity will be unhappy and a potential danger to humans and domestic animals.
- Wild animals can carry parasites that can be transmitted to humans. Some diseases are also transmissible to humans (e.g. rabies).
- Young babies need to be stimulated to urinate and defecate. This increases the custodian’s risk of exposure to disease and parasites.
As a last resort, explain that it is illegal for the public to keep wild animals except to rescue and transport the animal to a rehabilitator or veterinarian. Keeping the animal can result in a heavy fine and the animal can be confiscated and euthanized.
Most animals in distress need warmth, but wild babies cannot survive without it. Babies with closed eyes cannot thermoregulate and need an additional heat source to maintain their ambient temperature between 29.4 C° and 35 C°.
Older babies or severely compromised juveniles may also need an extra source of warmth, even during examination and feeding.
Newborns need 32.2 C° to 35 C° . Babies a few weeks old with their eyes still closed need temperatures of 29.4 C° to 32.2 C° . Once babies’ eyes are open, you can gradually lower the temperature to room temperature. Extreme or fluctuating temperatures can cause stress and weaken a healthy baby or even lead to the death of a weakened baby. The optimal choice for providing constant room heat to a baby is with an incubator.
Babies can also be warmed with a heating pad set on the lowest setting and never in direct contact with the animal. Check the container and the animal often to ensure that it is not too hot or too cold.
**For small males, you may see inflammation of the genital area
Symptoms:
Swollen, red, inflamed, enlarged genitals, especially the penis.
Crusts, swellings or scabs that may prevent the flow of urine
Common causes :
- The sucking reflex is very strong. Babies who have been without their mothers for a while may have suckled or suckled themselves to satisfy their thirst or need to suckle.
- Inadequate or incorrect formula
- Feeding is too infrequent
- The quantities in the formula are too small
- Babies have different levels of need to suck.
- Some babies suckle as a comfort device.
- Some babies can suckle while teething.
- Once the penis is irritated, sucking temporarily relieves the discomfort but increases the problem.
Possible treatment to prevent the problem:
- If the feeding is adequate (the right formula, the right frequency, the right amounts) and he still needs to suckle, you can dilute the formula so that there is more volume or you can offer plain water between meals.
- Offer the baby a pacifier (many people make homemade pacifiers with no holes etc.) Sometimes the baby will suck on his own and separation is not possible.
- Apply bitter apple or Yuck® around the area.
(Do not put the product directly on the raw area, it can sting a sore penis)
- Make a cozy bag for the baby so that the genitals are out of reach. Use a cotton jersey or baby sock with the tip cut off.
- Offer seedless orange segments as an alternative nursery.
- Offer interesting items to keep babies busy and entertained.
Possible treatment of genitalia :
- Wash the area with a mild antibacterial scrub.
- If there is a crust, soak and gently remove the crust. Swelling and crusting of the foreskin (skin covering the penis) can block the flow of urine and cause bladder and kidney problems. Make sure the baby can urinate at every feeding. If the swelling is too great, the opening may be too narrow to allow normal urine flow.
The bladder may need to be emptied. Consult your veterinarian. This may only be necessary once or twice until the swelling goes down. There may be tissue blocking the opening. Babies who cannot empty their bladders completely should be given oral antibiotics to prevent urinary tract infections.
It is best to assume that any wild baby presented to you is suffering from some degree of dehydration.
The symptoms of dehydration:
- Lethargy
- dry sunken eyes
- sticky mucous membranes
- poor skin elasticity.
The skin pinch test in some young babies is not in itself a good indicator of dehydration. Young animals like squirrels have loose skin. The skin of squirrels with closed eyes will tighten even under normal conditions. You will need to rely on other symptoms to determine dehydration.
Even if your baby seems healthy and responsive, and even if you know the baby has only been away from the mother for a short time, always treat him or her with rehydration fluids. This makes it easy for the baby to switch to the new formula you are about to give him.
Babies with dehydration should not be fed until rehydration has been completed for 24 hours or depending on the degree of dehydration. Giving food on a regular basis can actually cause his system to shut down and die.
The rehydration process itself can continue for 3 or 4 days. It is a mistake to stop the rehydration process too early. The animal can survive but it will be much more difficult for him.
Determine the percentage of dehydration of the animal:
Less than 5%.
- (gums and inside of the mouth) The gums are not sunken. the inside of the mouth is normal, not
- The eyes are normal, dry.
5-7%
- There will be a slight dryness of the mucous membranes
- The eyes are slightly sunken.
8-10%
- The mucous membranes will be dry, red and sticky.
- The eyes are sunken.
12% and more
- Very dry mucous membranes.
- The eyes are strongly sunken.
- The skin pinched lightly between the fingers will return to its normal position in less than a second.
- Mild to moderate. Signs of vomiting or diarrhea.
- There may be very little urine.
- The skin returns to its original position in 2-5 seconds.
- The animal may be lethargic.
- Increased episodes of vomiting or diarrhea.
- Weak pulse
- Urine is not very abundant
- The skin is back in place in >5 seconds.
- Depressed animal
- Excessive vomiting or diarrhea
- The skin does not return but remains in a tented form or is so tight against the body that it cannot be lifted.
- No urine
If the animal is not dehydrated, use rehydration fluids in normal amounts. Rehydration solution helps reduce shock, is easy to digest and is a good transition fluid from breast milk to formula, or from any food consumed in the wild to what the animal will be fed while you are caring for it.
Decide on the best way to rehydrate the baby
The method you choose will also help you decide which moisturizer to use. Ringer’s milk solution, which can be obtained from your veterinarian, can be used for all methods and is our personal choice. Pedialyte® and homemade salt, sugar and water solutions and commercial products similar to Pedialyte® are for oral use only. These solutions are intended for rehydration and not for long-term use.
Types of fluids
Rehydration fluids can be isotonic, hypertonic or hypotonic. Solutions that match the salt concentration of normal body fluids are called isotonic. These have the same “tone” of body fluids. Anything more concentrated or diluted will have a destabilizing effect on all cells and fluids in the body.
Solutions with higher concentrations are hypertonic (LRS with 5% dextrose, flavored pediatrics). Those with lower concentrations are hypotonic like carbohydrate-free sports drinks.
If the animal is severely dehydrated, isotonic fluids such as LRS, Normosol-R, or normal saline (NACL) are the best choices because they will not draw fluid out of the body’s cells. Once initial hydration and fluid balance are restored, a hypertonic solution (LRS with dextrose) can be used for the maintenance phase of rehydration. Once initial hydration and fluid balance are restored, a hypertonic solution (LRS with dextrose) can be used for the maintenance phase of rehydration. For a moderately to slightly dehydrated animal, a hypertonic solution such as lactated Ringer’s with 5% dextrose.
This can be purchased already prepared by Abbott.
Oral fluids
This method reduces stress levels and is the best way to quickly introduce fluids into a failing system. If the baby accepts fluids by mouth, your job is easy. Use a syringe with a soft nipple attached and give a measured, warmed amount, determined by the baby’s weight and condition. If you are hydrating a healthy baby, use regular feeding amounts. If the baby doesn’t understand what you’re doing, he may struggle and refuse to drink. If he is alert and able to swallow but not cooperating with syringe feeding, you may decide to tube feed him for the first few feedings. You will need to learn this technique from an experienced veterinarian or rehabber. Do not use the oral method if the animal is convulsing or unresponsive.
Oral fluids can be either commercial solutions such as Pedialyte® or Lactated Ringer’s Solution, or homemade solutions made from salt, sugar and water.
Recipe:
1 liter of warm water, 1 teaspoon of salt, 3 tablespoons of sugar. Mix well.
Subcutaneous fluids* (discuss with your veterinarian)
Subcutaneous is a medical term that means under or to be introduced under the skin. Sometimes a dehydrated animal will not take anything by mouth. He or she may be frightened, confused, nauseous, weak or have injuries that make it difficult or uncomfortable to drink. Giving subcutaneous fluids requires less animal handling and less cooperation. A warm rehydration fluid is injected under the skin and the animal absorbs the fluid into its system. Although the introduction of fluids into the animal is rapid in this manner, the fluid is absorbed more slowly than it would be if it were fed by mouth or through a tube introduced into the stomach and absorbed directly from the intestine. If the baby is taking only a small amount by mouth, give fluids subcutaneously as well. Often both methods are used. If you have never given subcutaneous injections before, ask a veterinarian or experienced rehabilitator to show you how. There are other rehydration methods used by veterinarians, but most shelters do not have the equipment or expertise to do them at home.
The Shortcut Method for Determining Replacement Fluids As presented by Erica Miller, DVM at the 2004 NYSWRC Conference These quantities should be administered in addition to the maintenance fluids.
- Day 1: Give 3.3% of the animal’s initial body weight three times over the first 24 hours
- Day 2: Give 2.5% three times a day for the next 2-3 days.
- Day 3 or 4: At this stage, the animal must be rehydrated. If the animal has ongoing fluid loss (vomiting, diarrhea, etc.), additional fluids may need to be administered.
Switch from rehydrating fluid to nutritive formula
Once the animal has been rehydrated for 24 hours, you can start introducing the formula gradually.
- Start with ¼ of formula (nutrient formula depending on the animal) to ¾ of rehydration fluid for a feeding or two
EX:
Raccoon
(1/4 of the formula being 1 part KMR powder to two parts water) + 3/4 of rehydration liquid (e.g. pedialyte).
- Then move on to ½ formula and ½ rehydrating fluid
- Then switch to ¾ of formula and ¼ of rehydrating fluid
- Finally, a complete formula
Move on to the next step when you see that the baby is tolerating the new formula. The animal must be able to digest the formula without problems such as loose stools or diarrhea. This is a gentle way to introduce the new formula into the baby’s system. This transition should take a day or two.
Quantities to be fed and frequency of feeding
Weigh the animal using a gram scale. We recommend using the 5% rule to decide how much to feed a baby mammal. The maximum comfortable capacity of the stomach is about 5-7% of body weight. If, for example, a baby squirrel weighs 100 grams, you will find 5% of 100, which is equivalent to 5. This indicates that 5 cc or 5 ml would be a good amount to feed an animal of this weight. The animal may not eat this amount during the first few feedings, but you know that the animal needs about this amount to provide adequate nutrition to its body.
Decide on the correct formula
Thanks to wildlife nutritionists, we can now feed our babies formula that is very close to their own mother’s milk and provides them with nutritional values close to what they would get from their own mothers. Currently, there are two main suppliers of milk replacement formulas for wild animals: Pet-Ag, Inc. and Fox Valley. PetAg® products include Esbilac, KMR, Multi-Milk, GME and Zoologic Milk Matrixes.
Esbilac is a milk substitute for puppies. KMR is a milk substitute for kittens. Multi-Milk Powder is designed to be used with the other substitutes when a richer formula is needed. Esbilac goat milk (GME) is recommended only for animals that are allergic or cannot digest other choices. Although it is easier to digest, it simply does not have the nutritional value that others do. Some rehabbers routinely choose goat’s milk substitute for all their animals or use real goat’s milk. We do not recommend it for long-term feeding as the protein and fat content is too low for most species.
The original products were made available as Zoologic Milk Matrix blends.
They have been assigned numbers: the first number refers to the percentage of protein and the second number refers to the fat content. Each species needs specific dietary values for proper growth. Some species will require a combination of formulas to be as close to breast milk as possible.
Zoologic 42/25 is similar to KMR (40/27)
Zoologic 33/40 is similar to Esbilac (33/40) and
Zoologic 30/55 is exactly the same as Multi-Lait
Some people make their choices because of the ease of mixing, others because of the price.
We believe that poor results with one product or another are often due to external factors, such as improper storage and high temperatures during shipping.
There are so many variables in the preparation of the formula…water quality, measurement techniques, mixing and storage methods, and these variables affect the quality of the formula made from the powders. In addition, animals from different regions or even from the same litters may have different nutritional needs.
Think carefully about your choice. If the formula you are using is making your baby sick or weak, try something else.
But please don’t use homemade formulas. The nutritional value may be insufficient for the baby’s needs and may cause long-term health problems. Soy-based formulas are not suitable for wildlife and can cause health problems for your wild babies.
Colostrum
Colostrum is the milk produced by the mother during the first days of a baby’s life. It contains important components, such as protein and calories, that contribute to a healthy gut microflora and nutrient absorption. It also provides antibodies to protect the baby.
Younger babies benefit from adding colostrum to their formula. In older babies, the antibodies are not absorbed, but other elements provided by the colostrum are important. Studies using bovine (cow) colostrum on dogs under two years of age have shown that colostrum can benefit older juveniles in the following ways:
- Increased diversity of gut microflora, which reduces the risk of bacterial pathogens invading the gastrointestinal tract
- Improves the mucosal barrier Gl which helps neutralize potential pathogens and stabilize the intestinal microfiore
- Reduces the risk of gastrointestinal disorders and diarrhea caused by stress
- Improves the overall immune system
Thus, it appears that bovine colostrum would benefit orphaned wild animals in the same way.
Probiotics
Beneficial bacteria (probiotics) can be added to formulas and fluids to help establish and maintain the proper microbial balance in the intestinal tract. This is available in paste form or powders. Powders mix well in formulas and may be easier for small animals to swallow. Bene-Bac® products are from Pet Ag and LA 200 is from Fox Valley. Lactobacillus and acidophilus can be purchased at a health food store.
Nutrical, Nutristat, Energel, Enervite are all nutritional supplements, concentrated high-calorie pastes for more energy and strength, and to stimulate appetite recovery.
Feeding frequency (see the table of animals)
Intestine and bladder
***Baby wild mammals that are still too young to have their eyes open must be stimulated at each feeding to urinate and defecate.
If this is done before each meal, the results can become an important diagnostic tool. Use soft cloths soaked in warm water and rub the genital area. Use quick but gentle movements. This should be done even if there are signs in the litter or on the fur that the animal has shed some of its own. If the baby is not stimulated and the bladder is not completely emptied, the baby may develop a urinary tract infection or suffer damage to the bladder or kidneys. Most mammals urinate and defecate on their own shortly after opening their eyes. You may want to stimulate them even after they have begun to eliminate on their own. This keeps the bedding fresh longer, saves on laundry, and babies won’t smell like urine.
The baby may not produce stool for several days after arriving at the shelter, especially if he or she is dehydrated. Often, the first stools are very dark, black or almost black. This is to be expected when an animal arrives dehydrated. Do not panic! The first stool reflects what happened before the baby reached the shelter. If the stomach is soft, everything is fine. If the abdomen becomes hard and the baby does not produce stools, there may be a problem with constipation or bloating.
Black stools with the appearance of coffee grounds may indicate bleeding in the gastrointestinal tract due to trauma or illness.
The stool should be well formed. If so, follow your chosen liquid feeding program. If stools are loose or diarrhea is present, you will need to determine the cause and adjust treatment and feedings accordingly. After the baby has been drinking formula for several days, the stool will be golden yellow.
Feeding the baby
*Your tools ready
- Gram scale
- A good light
- Pen and paper to record weights and other relevant information
- Tissues, paper towels
- Soft and warm linen to wrap the baby in
- Extra clean wipes to wash the baby and change the baby’s bedding
- Hot water
- Formula
- Feeding tools, syringe caps
- Bottle or syringe warmer
- Litter garbage can or garbage bag
Syringes are the most common choice of feeding tool for very young, very small babies or for the first feeding. They are available in many styles and sizes and can be used with different accessories to make feeding easier for you and the baby. In addition, the syringes allow you to give the baby a precise, measured amount of formula and clearly see how much the baby has taken. A syringe allows you to control the flow of preparation and helps reduce the incidence of aspiration. A very small baby or earling (baby without fur usually less than a week old) should be fed with a 1 cc syringe.
Start older babies with a 1 cc or 3 cc syringe. A small syringe will deliver fluids more slowly than a large one using the same pressure. Choose a larger syringe size as the amount of formula increases. If the baby aspirates, go back to using smaller syringes.
Pet and human bottles are only recommended for larger species, such as raccoons, porcupines and beavers, and only for older babies, or once the baby is used to drinking from a syringe.
Mix the formula ahead of time to allow air bubbles to settle.
You can have syringes already filled with formula placed in warm water or you can have a container of heated formula and fill each syringe as needed.
Wrap the baby in a soft cloth
This keeps him warm while he nurses, makes the baby feel more secure and gives you more control over his movements. It is especially helpful to wrap a restless baby whose legs are always in the way of the syringe. It is natural to want to hold the baby as you would hold a human baby. Don’t do it!
Most wild babies nurse from their mothers by resting on their bellies or sitting facing them, not on their backs. A baby who is fed in a supine position will be at greater risk of aspiration.
Most baby mammals feel comfortable when they are positioned on their stomachs with their bodies tilted at an angle of about 45 degrees. Support the midsection so that the back is not arched in an unnatural position. Support the feet with your hand, the bandage or on a table. The animal will feel insecure and uncomfortable with its legs dangling in the air.
Hold the baby firmly, and be careful where you place your fingers. Keep your fingernails trimmed short to reduce the possibility of scratching or poking babies. Place the pacifier in the baby’s mouth. It does not need to be placed too far away. Hold the end of the plunger and push a small amount of formula at a time, letting the baby swallow between pushes. Observe the baby to see what his sucking rhythm is and try to adapt to it. If the plunger is not well retained, babies who suckle hard can suck up the formula.
Most babies have a natural sucking reflex. A newly admitted baby may not suckle well for the first few days. Stroking the side of the face, neck or back can often stimulate the sucking response and help babies accept a new feeding method or taste.
If you are having trouble getting babies to accept feeds, remember that they are scared and usually don’t feel very well when they arrive. Be patient with them. It may take several feedings before they realize that feedings are a good thing.
Using a syringe instead of a human bottle allows the baby to taste the formula immediately. The sucking action on a bottle is different from the mother’s breastfeeding and it usually takes several feedings for the baby to adjust to a bottle.
Open mouth
There is a style of breastfeeding that you can see while the wild babies are nursing. It is common in squirrels, raccoons and some other species. It is called by many names, “trance nursing, flat tongue nursing, open mouth nursing”. This is what happens when a baby who is suckling well suddenly opens his mouth and flattens his tongue. Because the mouth always makes the same sucking movements, the baby always thinks he is sucking.
This is not a crisis. It’s normal for a baby to be relaxed during a breastfeeding session or for a baby to have fallen into a light sleep. He will start sucking on the nipple again if you touch his tongue or the side of his mouth, or if the milk stops flowing onto his tongue.
Inhalation of the formula
The inhalation of the formula is also called “aspiration” or “squeaking”. Instead of flowing down the throat, the formula is inhaled into the nasal passages and through the nose. Some of the formula can reach the lungs and cause aspiration pneumonia.
Babies who develop respiratory symptoms should be treated with antibiotics. We found Amoxicillin® or Clavamox® to be inexpensive and effective. Do not use any medication from the penicillin family or any medication ending in cillin or mycine with rabbits. When giving antibiotics, give the baby beneficial Gl bacteria (give an hour after or on an empty stomach before subsequent feedings). Continue probiotics for several days after a course of antibiotics to restore the intestinal flora.
One of the main causes of diarrhea in baby mammals is overfeeding. The 5% rule gives you a rough idea of the amount per meal and you need to adjust for individual differences. Some baby mammals will continue to suckle as long as you allow them to, so you need to decide how much and how often.
If the pet still seems hungry after a feeding, feed him a little more and see if he is well tolerated. The stomach should be full, but still soft. It should not be hard and stretched like a balloon. If you start to see very loose or soft stools or diarrhea, reduce the amount of formula at the next feeding. Another sign of overeating is light-colored stools, such as pale yellow, beige or white.
Most newborns need to be fed as often as 8 to 10 times a day to get the nutrition they need. They can only take small amounts at each feeding, so more feedings are needed. They may need to be fed overnight and will benefit from an extra supply of rehydration fluids each day as they dehydrate very quickly. If you can’t do this, take the animal to another shelter that can. Babies that are just starting to grow fur should be fed about every 3 hours. See table for formula, quantities and frequency.
Underfed babies may have infrequent, hard, dark stools. The baby will not gain weight. Be sure to weigh daily and record weights.
Constipation
Constipation is characterized by hard or infrequent stools, straining or crying during defecation. Although this condition in the mild stages is not life-threatening, it can make the baby uncomfortable.
Common Causes:
- Lack of food intake
- Undernourishment
- Dehydration
- An overly concentrated formula.
- Do not stimulate the baby to defecate regularly
- Inappropriate foods
- Stress
Possible treatments:
- Rehydrate the animal. Providing extra fluids helps relieve constipation.
- Check the proportions of water and dry formula. Moisture can make formula powders more compact and dense, resulting in a more concentrated formula.
- Give a dose of mineral oil orally, at a rate of 2 to 5 ml per kilogram. If this does not work, do not repeat.
- Another option is Laxatone® which contains petroleum jelly and is used as a hairball treatment for cats. This product acts as a lubricant to help evacuate fecal matter. Lactulose (Enulose®) is another product that helps soften stools.
- Consider adding probiotics, Lactaid® or enzymes to help the gastrointestinal tract. The best time to give probiotics is on an empty stomach.
- For older babies, consider adding fiber such as pumpkin, Metamucil®, high-fiber cereal or applesauce to the diet.
- A warm water enema can also be administered with a small feeding tube and syringe. Be sure to lubricate the tip with Vaseline or KY Jelly. Just give a little warm water, then stimulate the baby to defecate.
Bloating
Babies don’t usually arrive at your shelter bloated. Someone usually causes this condition. Any condition caused by the caregiver is called an iatrogenic disorder. Bloating is an accumulation of gas or stool. This is an indication that the gastrointestinal tract is not working or not working well. Bloating can kill.
Symptoms:
- The animal does not produce feces.
- It can be difficult, crying and obviously uncomfortable.
- The stomach may be tight and stretched or may feel spongy instead of soft.
- The animal is probably suffering.
Common Causes:
- Supercharging
- Feeding a cold baby
- Feeding a cold formula
- Sudden change of regime without transition
- Changes in diet
- Feeding the wrong formula
- Feeding a spoiled formula
- Internal parasite
- Constipation
- Formula intolerance (Try enzymes to help digest lactose)
- Feeding large quantities instead of more frequent and smaller meals
- Using contaminated water or equipment
- Excessive air swallowing
- Immunities
- Infection or illness
- Internal abnormalities such as a genetic defect resulting in an inability to digest properly
Possible treatments:
- Make sure the animal is warm
- Once you have identified the bloating, stop feeding until it is resolved.
- Stimulate the baby to urinate, defecate or pass gas. Place the baby in warm water up to the chest and massage the belly for about 5 minutes. To massage, place thumb and index finger on either side of the baby. Starting under the arms and using light pressure, slide your fingers down the sides to the hip area. The idea is to stimulate motility and ensure that any gas moving downward is expelled. Keep the baby warm. Dry gently with a soft cloth. (Do not use a hair dryer, as the noise and blowing sensation can cause stress and further compromise the baby).
- Repeat the process every half hour and let the baby rest between massages. If after soaking the problem does not resolve, do not give up.
Another option is to lay the baby on his or her stomach on a warm heating pad and gently massage the sides. The advantage of this method is that the baby does not run the risk of getting cold.
For mild cases, use a carefully measured dose of infant simethicone® to relieve some of the pain and distress caused by gas.
Once the bloating is resolved, try to identify the cause to ensure that it does not recur.
Metaclopramide (Reglan®, Maxolon®) may increase motility in the upper gastrointestinal tract. (1 mg/ml oral solution) or Ranitidine (2-5 mg/kg po q 12 hours).
For pain management, Meloxicam 0. 1-0.2mg/kg can be administered once daily 60 Effects last between 12 and 24 hours.
The bloating is very painful. Bloating is not usually seen in older babies.
Once the seizure is over, offer the baby rehydration fluids.
Diarrhea
Diarrhea may be characterized by frequent loose, unformed or watery stools that may contain mucus or blood. Stools that have a soft or pudding-like consistency are not necessarily signs of diarrhea. A single loose or watery stool is not a symptom of diarrhea. Loose stools may be normal for that particular animal. Diet is also a contributing factor to stool formation.
Symptoms:
- Frequent bowel movements
- Liquid stools that occur in cycles
- Mucus or blood with feces
- Fecal matter, odor or matted fur around the anus
- Dehydration
- Pain caused by cramping or tissue irritation
- Lethargy
- Fever
- Prolapse
Common causes of diarrhea:
- Inappropriate food or too much food.
- The baby may have eaten something inappropriate on its own.
- The animal may be intolerant or allergic to certain foods and not be able to digest them.
- The baby may have eaten something poisonous or toxic.
- The baby’s mother may have been ill or the baby may have been breastfeeding a deceased mother.
- The baby can be stressed!
- There may be a viral disease, bacterial infection, protozoan diseases or endoparasites causing gastrointestinal disorders.
- There may be an obstruction due to a foreign object or a twist due to an injury.
Animals may arrive with diarrhea present or diarrhea may occur several days later due to any of the above causes.
A fecal test is a quick and inexpensive way to determine certain causes of diarrhea, such as endoparasites, certain bacteria and certain protozoa. If you find a pest, treat it accordingly. This may or may not be the cause of the diarrhea, but should be treated immediately.
If you don’t know the cause of the diarrhea, you should always provide aggressive supportive care with rigorous rehydration. Untreated diarrhea will lead to dehydration and sometimes death.
There are two main reasons for deworming animals. The first: Protect them from intestinal worms. The second is to protect you and your family from parasite contamination. Some animals of the fauna are carriers of parasites very dangerous for the man so this step is not to be taken lightly.
List of dewormers used:
Ivermectin
Ivomec® Promectin
Ivermectin is used to eliminate internal parasites. It is effective against most common intestinal worms (except tapeworms and whipworms). It is excellent for treating scabies mites and ear mites, larval heartworms (but not adult heartworms) and some lice. It is also effective against fleas and ticks. Ivermectin has been used with good results to treat maggots that have entered an animal.
Form: Injectable (1%, 0.27%) and paste*.
Strength: 1% Injection is 10 mg/ml. When dosing small animals (squirrels, rabbits, young opossums), it should be diluted further. Larger animals (older opossums, foxes, etc.) can be administered at full strength
Frequency: This medication is usually given once and then repeated every 10 to 14 days. Discard dilutions after two weeks.
**For exact measurements contact your veterinarian.
Fenbendazole
Panacur®, Safe-guard® and
This product is used to eliminate and control roundworms, hookworms, whipworms, nematodes and tapeworms. It is also effective against giardia. Forms: drinkable suspension, paste, granules,
Dosage: 100 mg/ml as a suspension/ Dosage: 50 mg/kg (deer-10 mg/kg).
Frequency: SID for 3 to 5 days. Repeat the treatment in 2-3 weeks. When treating Giardia, for 5 to 10 days.
**For exact measurements contact your veterinarian.
Levamisole
Levasole @, Tramisol @
It is a broad spectrum parasiticide (hookworm, lungworm, roundworm and heartworm). Levamisole can be dosed at half the weight to stimulate the immune system.
Form : Injectable, tablets
Strength: 136.5 mg/mI undiluted. Make a 10% dilution by mixing 9 volumes of sterile water with 1 volume of levamisole. This gives a concentration of 13.6 mg/ml.
Dosage: 6.1 mg/kg
Frequency: It is the recommended dewormer for opossums. The National Opossum Society recommends deworming at intake for opossums over 200 grams. Repeat at 14 and 21 days for juveniles and adults.
The National Oppossum Society recommends injecting the medication rather than giving it by mouth because it will not be as effective on the immune system if given by mouth.
**For exact measurements contact your veterinarian.
We also recommend that you ask your doctor for a renewable prescription for deworming at least once a year.
When animals arrive at your shelter, we don’t know what viruses they have been exposed to or what they may be incubating. A baby who looks healthy may develop symptoms days or weeks after being admitted.
Optimally, babies less than 3-4 weeks old should be quarantined from older members of their species and from species that are vulnerable to the same diseases.
The best protection you can give babies is immunization against the common diseases seen in your area. Rehabilitation vaccination schedules should be similar to pet shelter vaccination schedules due to the much higher risk of disease. Vaccinating as early as possible gives babies lasting protection.
We never know when the next intake will harbor a deadly virus that will turn our rehab season into a nightmare. The mortality rate from feline parvo (feline panleukopenia), canine distemper and other parvo diseases is high.
The first dose and subsequent series of doses are based on the experience of pet shelters using the product (which is generally administered earlier than the label recommendation for animals not living in shelter environments) to protect their animals from outbreaks. There are many other vaccines available on the market that have not been mentioned, many of which protect against a multitude of diseases. If a disease such as leptospirosis is not prevalent in your area, you can choose a vaccine without it.
When there is a high risk of disease based on reports of sick animals in your geographic area, animals must be vaccinated against these diseases upon admission. Waiting even one day can put the animal at risk. Most shelters will vaccinate animals before they are brought to the Center (even injured and slightly ill animals). Sick animals cannot be vaccinated and must be quarantined.
Vaccinating a sick animal can further weaken the immune system. The animal may not be able to develop an immune response at this time.
The choice of vaccine may be very different for the shelter that has one or two litters of animals versus the shelter that may have 15 to 50 animals of the same species in its facility.
Shelters that house one or two litters of raccoons where the incidence of disease in the wild population is low may feel comfortable choosing a killed virus vaccine (when available) since exposure to active disease is less risky and there is less concern about how long it will take for the animal to be protected after receiving the vaccine. Others receive new animals throughout the season, know that the disease is present in their area and need their animals protected as soon as possible, should choose a vaccine that can give them the protection they need.
Some vaccines (depending on the type of vaccine) provide protection within a few hours of administration, which can make a difference for the animals in your care. Each type of vaccine has advantages and disadvantages. In high-volume facilities such as shelters, modified or recombinant live vaccines may be more effective.
Vaccination offers the best protection against the disease, but is not a magic bullet.
Animals incubating a disease or animals that are extremely weak, stressed or starved may not be able to produce immunity.
In addition, it takes time (hours, days, sometimes weeks (depending on the vaccine) for the animal to develop immunity.
Types of Vaccines:
Modified live vaccine: (MLV) is a vaccine that contains virulent or attenuated virus particles to promote an immune response in the animal. It provides the animal with a faster and more effective immunity.
Attenuated vaccine: a vaccine containing weakened microorganisms.
These vaccines develop a more durable immunological response.
Benefits
- A single dose of MLV vaccine can provide protection
- Provides relatively rapid onset of immunity (hours to days (5-7) and protection is long lasting
- Better able to be effective in the presence of maternal antibodies
- Can prevent disease
- Can prevent the spread of the virus in the environment
Disadvantages
- Distemper vaccine can produce significant disease in severely immunocompromised animals (genetic immune suppression and Parvo infection).
- Immunosuppression due to stress and poor nutrition is not thought to have shown an increase in vaccine-induced disease.
- MLV vaccines can be inactivated by improper storage or handling
Feline panleukopenia and other parvovirus vaccines can cause death or illness in fetuses and babies under 4 weeks of age. Do not vaccinate pregnant animals with these vaccines.
Killed or inactivated vaccine: vaccine containing a killed virus. Killed vaccines often contain an adjuvant to boost the immune response. The killed virus is suitable for disease-free environments and pregnant animals. The rabies vaccine is always a killed vaccine.
Benefits
- Will not cause disease even in very young animals and pregnant females
- More tolerant to mishandling and storage
Disadvantages
- An immune response to provide protection will not be acquired until 1-2 weeks after the administration of a booster vaccine 2 to 3 weeks after the initial vaccinations. This means that animals will not be protected until five weeks!
In facilities that care for a small number of animals and can keep litters quarantined from each other, this may not be as problematic as for shelters that care for a larger number of animals. Immune response may be shorter in duration compared to other vaccines
Adjuvants are generally required
Recombinant vaccine: this is a vaccine that combines the physiology of one microorganism with the DNA of another. This vaccine helps create immunity to diseases that have complex infectious processes. The FDA recognizes three types of recombinants. These vaccines may or may not contain an adjuvant.
Benefits
- Effective against merial distemper and offers rapid protection similar to MLV
- Efficacy in the presence of maternal antibodies
- No chance of inadvertently causing disease
- Generally does not require additives
Disadvantages
– More expensive
Rehabilitation conditions for wildlife;
- a raccoon, striped skunk, fox, wolf or coyote must be vaccinated against rabies within one week of arrival at the rehabilitation site;
- a fox, coyote, raccoon, striped skunk or white-tailed deer may not be transferred from the south shore of the St. Lawrence River to the north shore for rehabilitation or for release following rehabilitation;
- a fox, coyote, raccoon, striped skunk or white-tailed deer may not be moved more than 75 km from the place of capture for rehabilitation, or for release following rehabilitation (this distance is increased to 150 km for an animal originating from certain areas in the northern part of the province, i.e. hunting zones 12 to 14, 16 to 19, 22 to 24, 28 and 29);
- Before being released, a black bear must be identified with an ear tag.
IMPORTANT ******* Quantities
Weigh the animal using a gram scale. We recommend using the 5% rule to decide how much to feed a baby mammal. The maximum comfortable capacity of the stomach is about 5-7% of body weight. If, for example, a baby squirrel weighs 100 grams, you calculate 5% of 100, which equals 5. This indicates that 5 cc or 5 ml is a good amount to feed an animal of this weight. The animal may not drink this amount during the first few feedings, but you know that the animal needs about this amount to provide adequate nutrition to its body. calculate

VIDEO : How to feed a baby cottontail rabbit.
Age Indices: Appearance and Behavior
1-3 days: The average birth weight is between 15 and 25 grams. Babies are born with their teeth, eyes and ears closed and without hair. The pigment may be visible under the skin. At this age they should be fed formula 2-3 times a day.
4-7 days: Their eyes and ears are closed, their skin is pink and no fur is visible yet. Continue to give formula 2 to 3 times a day. They weigh about 35 g.
7-10 days: The eyes and ears begin to open. The rabbits will start to nibble on the dry grass in the nest. As soon as they start to nibble on solid foods, give them lactobacillus or other probiotics to aid digestion. Continue until you reach the exit. Offer the formula twice a day. If the rabbit no longer wants to suckle, offer the formula in a small, shallow dish and leave it in the cage for only a short time to avoid bacterial growth. The weight varies from 35 to 50 g.
10-12 days: The legs and ears have fur. The ears have spread and they begin to move in response to the noise. The eyes are completely open. Rabbits jump forward and make a noise when they are upset. Offer the formula once a day. They may not be interested. The weight varies from 45 to 60 g.
12-14 days: He can urinate on his own, but continue to stimulate him until his eyes open or until you can no longer get him to produce urine. Begin weaning by carefully adding one new food at a time. You can start offering fresh fine blade grasses. The weight varies from 55 to 75 g.
14-18 days: They are fully furry, alert, nibble solids and bunny hop. Offer greenery from the fields. The weight varies from 70 to 85g.
18-22 days: Their eyes are bright and alert. They weigh 75 to 100 g.
22-28 days: They are ready to be released. The rabbits should weigh between 100 and 210 grams.
Why are rabbits so difficult?
Baby rabbits are born with very few microorganisms in their digestive tract. Breast milk provides natural bacteria, enzymes and fatty acids. Fatty acids act as a natural antimicrobial. All these components help the gastrointestinal tract of baby rabbits to function properly. This is an ongoing process for rabbits while they are nursing. When babies begin to wean, at four to six weeks of age, they lose the guardianship of breast milk components. Often, babies seem to be doing well until this critical stage is reached. Breast milk and cecotropes begin to introduce the necessary adult flora (to digest solid foods) into the gastrointestinal tract of babies.
In addition to the “good” flora, other elements such as bad bacteria, viruses and protozoa are introduced into the intestine. There is a balance under normal conditions, but when an animal’s immune system is compromised by injury, illness, pain or stress, the balance changes and the animal can be overwhelmed by disease. Anything that upsets the balance of the gut can lead to diarrhea, bloating, dehydration and death.
Vegetable fibers are difficult to metabolize. The plant foods that rabbits eat are also low in nutrients, so they must eat constantly. Food stays in the stomach of rabbits longer than other mammals. The plants are decomposed and fermentation occurs thanks to the work of enzymes and the intestinal flora.
Rabbits practice coprophagy. They ingest the caecotrope (nocturnal feces), which comes in the form of small piles of dark, mucus-covered stool. Caecotropes are different from normal daytime stool pellets. Caecotropes contain a highly concentrated form of vitamin B and other elements manufactured in the GI tract of rabbits.
They need a continuous flow of roughage through the gastrointestinal tract to obtain the necessary nutrition. They get most of their water from fresh herbs and grassy plants in the fields.
The complexity of the rabbit gastrointestinal tract makes it a challenge in the rehabilitation situation. In addition, the stress caused by captivity creates a situation where rabbits are more vulnerable to developing health problems.
Refuge rabbits are vulnerable to :
- Infection by bacteria due to not receiving the natural antimicrobial protection of mother rabbit’s milk
- Disease (with or without diarrhea) caused by pathogens that may be present in the intestine (coccidia, e coli, C. spiroform, viruses, etc.)
- Gastrointestinal stasis (bloating)

Weaning regimen:
90% puppy and kitten food as the main staple.
10% Fruits, cereals, nuts, eggs, chicken, mice, raw vegetables, etc.
Weaning process:
To begin the weaning process, leave solid foods such as small pieces of Fig, banana, oatmeal cookies, raisins, whole grain cereal or small breed kitten or puppy food with the babies. Kibbles can be softened with warm water or formula.
Natural Food
- Acorns, beech, hickory, hazelnut and other seeds or nuts
- Frogs, salamanders, fish, turtles
- Crayfish and other crustaceans
- Grasshoppers and insects
- Earthworms
- Small mammals (mice, moles, birds, etc.)
- Eggs
- Fruits and berries
- Plants such as wheat, corn, oats, barley, sunflower, some grasses, etc., are used as a source of energy.
- deer carcass and other carrion
Special circumstances:
Geographic differences: Raccoons from warmer climates are much smaller than raccoons from colder climates. Raccoons in colder climates should be healthy and have a full coat before release.
Health problems:
Raccoons are considered a vector species for rabies. Use extra caution when handling them. Shelter managers handling species should be vaccinated against rabies.
Vaccine recommendations for raccoons
Vaccinate your raccoons against rabies with Rabvac3 or Imrab3 at 12 weeks of age and give a booster at discharge if possible. Purevax®, Merial’s rabies vaccine, can be given as early as 8 weeks of age.
Vaccinate against feline parvovirus (panleukopenia) in cats with Fel-O-Vax® or another distemper vaccine (dead virus). Raccoon Parvo most closely resembles cat Parvo, so the vaccine will help prevent this disease.
Start vaccinations at 8 to 10 weeks of age. Heska and Pfizer manufacture intranasal and intraocular vaccines. These vaccines can be given safely to babies as young as 3 weeks. A second dose is recommended at 12 weeks of age. Animals that reach 20 weeks of age or more need only one dose.
Raccoons must also get the vaccine for canine parvo. The raccoon parvovirus strain is different from canine parvo. It is more similar to feline paleukopenia or Parvo du chat.
The incubation period for canine distemper is usually 14 days, but some strains can incubate for more than 4 weeks. When distemper is prevalent in your area, babies 2 weeks of age and older can be vaccinated with Boehringer Ingelheim/Meriel Recombitek® distemper vaccine.
The canine distemper vaccine for ferrets (PureVax® Ferret) is also produced by Meriel and can be given at 2 weeks or older. Both of the above vaccines are vectors for canary pox and therefore cannot cause disease. Meriel tested Recombitek® and found that it offers protection regardless of maternal antibody interference. According to Dr. Schultz, MS, Phd, DACVIM, findings presented in 2004, one dose of Recombitek® vaccine against distemper virus can provide protection in 4 hours. It is preferable to vaccinate at admission or from 4 weeks of age with Recombitek®.
At least two doses of these vaccines should be given with an interval of 2 to 4 weeks between doses. Merial canary pox vector products are safer than vaccines that contain the modified live distemper virus.
An article published in the Wildlife Rehabilitation Bulletin, Spring 2014, Immune Response in the Common Raccoon (Procyon lotor) to Modified Live Canine Distemper and Feline Paleukopenia noted that maternal antibody interference can last up to 20 weeks. To ensure protection, the last vaccine should be given after 20 weeks of age.
– Vaccinate against leptospirosis only if it is prevalent in your area.
Raccoon roundworm is a concern, but it is controllable. Deworming for roundworms and other parasites on admission, as soon as the baby is stable, and then every month until release.

Formula: Milk recommended for species with low protein and high fat requirements for neonatal growth.
Alternatively, feed newborns a formula of 1 part Esbilac powder and 2 parts water .
VIDEO: How to feed a baby grey squirrel
Weaning regimen:
- Food for rodents
- Natural food
- Broccoli, sweet potato and fruit can be given as treats
- Whole grain cereals
Natural diet : Omnivore
- Nuts (acorns, hickory, beech, spruce) and seeds
- Shoots, buds and flowers
- Mushroom (fungi, lichens, moss)
- Fruits (strawberries, peaches, pears, apples, cherries, blueberries, black berries, grapes, etc.)
- Cambium of many trees
- Caterpillars
- Occasionally eggs
Release Criteria:
Locate release sites in mixed hardwood forests, especially those with acorns, hickories and Beech. Choose an area that is not overcrowded with an existing population of gray squirrels. Release at the beginning of the day. Grey squirrels are scattered hoarders. In geographic areas where the ground covers in winter, do not release too late in the season, as they need time to bury their winter food supply.
Special considerations:
Older squirrels can be very territorial when new squirrels are introduced into a pre-release cage. It is best to put different litters of the same size in the pre-release cage at the same time. Offer several nesting boxes if possible. This reduces the risk of conflict. Provide logs, large branches for climbing, a deep floor covering of soil and leaf litter. Their teeth turn orange when they are 4-5 months old.
Health problems:
Scabies is often a health problem for squirrels.
No vaccine is required for squirrels.
Pox virus: Is an infectious bacterial disease of the upper respiratory tract that has been documented in grey squirrels. Symptoms include coughing, weight loss, lethargy, loss of appetite and secondary pneumonia. Quarantine all animals suspected of having the virus to avoid spreading the infection to healthy animals.
The virus may be present in the respiratory tract for months after treatment, so it is best to keep animals in quarantine for several months. Can be treated with broad spectrum antibiotics. ***Ask your veterinarian for more information.

Age/appearance indices and behaviors;
Birth at one week:
À At birth they are naked, their skin is pink and their eyes and ears are closed. Feed every 2 hours. Feed once during the night. They weigh about 7 grams at birth.
Two weeks: They begin to vocalize and are able to make alarm calls. The fur starts to appear. They weigh about 20 grams. Feed every 2 to 3 hours. Eliminate night feeding.
Three weeks old:
They weigh about 30 grams. Their eyes and ears begin to open. The head and tail are well furred and take the adult coloring. Formula feeding every 3 to 4 hours.
Four weeks old:
They weigh about 40 grams. Continue to give formula every 3 to 4 hours. They start to climb. The lower incisors begin to emerge.
Five weeks: The babies are fully furry and move with a purpose. The upper incisors erupt. Their eyes are completely open and the babies weigh between 40 and 50 grams. Feed every 4 to 5 hours. Provide a variety of weaning and natural foods in the cage.
Six to eight weeks: They begin to wean, start to leave the nest and explore the area. They weigh between 60 and 80 grams. Feed 3 times a day. Begin to taper off formula feedings as they eat more solid foods on their own
Eight – Ten weeks: They must be fully weaned and ready to enter the outdoor pre-release cage. They weigh between 120 and 150 grams.
Fourteen weeks:
Unleash
Formula: Milk recommended for species with low protein and high fat requirements for neonatal growth.
Otherwise, feed newborns a formula of 1 part Esbilac powder to 2 parts water.
Weaning diet :
- Food for rodents
- Primate/monkey food
- Natural foods
- Small pieces of fruit and vegetables
- Whole grain cereals
Babies should be fed only rodent food until they are eating well. Once they do, you can offer fruit and occasionally nuts. This ensures that they will consume a nutritionally complete diet. If you are having trouble getting the squirrels to eat the rodent food, don’t put other food in the cage.
For older babies who refuse formula, babies with mouth problems, or babies who have difficulty holding food due to a physical disability, the recipe below is a great alternative.
Nut balls recipe: ground rodent food, a spoonful of applesauce and a little peanut butter mixed together, then roll in peanuts and refrigerate.
Natural food :
- Pine cones
- Mushrooms
- Lichen, moss
- Nuts (pine, acorn)
- Seeds
- Fruit
- Bark
- Buds
- Flowers
- Deer antlers or other type of bone
Special circumstances:
Red squirrels are cache hoarders, not dispersed hoarders like gray squirrels. When they are upset, they emit a high-pitched sound that is often mistaken for a bird call.
Red squirrels have an aggressive, argumentative and territorial nature. Although they are smaller than gray squirrels, they tend to be bullies. It is advisable to house them separately from the grays once they become juveniles.
Health problems:
Sometimes red squirrels have unexplained hair loss. There is nothing to worry about once you eliminate mites and nutritional deficiencies as a possibility. Keep the squirrel warm during this shedding period and feed it a balanced diet. This shedding is different from the spring and fall molts.

Birth season: May to July
Gestation : About 63 days.
Litter size: 6 on average. Between 2 and 10 babies.
Natural habitat:
Skunks prefer open fields, lawns, woods, meadows, suburban and urban areas. They like to spend time under brush piles, in wood piles and under buildings, preferably abandoned.
Period of activity: They are mainly nocturnal, but can be crepuscular (out early in the morning or early evening, occasionally seen during the day). Skunks are nomadic and usually don’t stay in one place for long, unless there is a good food source or a warm place in cold weather. In cold weather, they like to be near or under buildings, barns, porches and decks. The mothers will stay in the same place for the time it takes to raise their young.
Age Indices: Appearance and Behavior
Birth: Their birth weight is about 15 to 35 grams . Their eyes and ears are closed. They have pink, wrinkled skin with just a suggestion of marks. The skin is dark where their marks will be dark. The fur is sparse. Feed every 2-3 hours with a night feed.
1 week: Their weight is between 35 and 50 grams. There is more fur and the brands are more defined. They can barely move and make chirping sounds. Feed with the formula every 2 to 3 hours. Eliminate night feeding.
2 weeks: Baby skunks weigh about 90 grams. They are fully hairy and can already give off a slight musky smell. Feed the formula every 3-4 hours.
3 weeks: They weigh between 100 and 200 grams. Their ears are open and they start to react to sounds. Their eyes begin to open. They begin to raise their tails as a warning and may release enough musk to discourage intruders. They are able to crawl but cannot yet walk. Feeding with milk formula 4 times a day. Offer a shallow dish of water.
4 weeks: The weight can vary between 200 and 350 grams. They can spray a light musk and still walk unsteadily. They vocalize with sounds. Offer weaning foods such as small pieces of fruit, puppy kibble or canned food. Baby skunks usually dry out easily. Feed the formula 3 times a day. Provide them with a spacious cage with nesting boxes, a pot of dirt, a dish of shallow water and plenty of weaning and natural foods.
5 weeks: Their teeth start to grow and they begin to eat soft weaning foods. Offer softened food, scrambled eggs, mealworms, cut up vegetables and fruit. Breast milk twice a day. If babies are reluctant to suckle, put a small amount of formula in a small shallow lid and place it in the cage. Change the formula often and clean up spills immediately.
6 weeks: The olfactory glands are now fully developed. Baby skunks begin to play with each other and with small toys. They can be moved to an outside cage.
7 weeks: They should eat solid foods regularly. Add a wider variety of foods such as chopped mushrooms and vegetables, nuts, scrambled eggs, hard-boiled eggs with the shell, clumps of grass with the clump, mice and insects.
8-10 weeks: They should be weaned and eating a wide variety of weaning and natural foods.
10-12 weeks: Feed them basic puppy food, but add larger amounts of their natural diet foods.
12-14 weeks old: If they are shy with humans and dogs and present the appropriate warnings when approached, they are ready to be released.
Formula:
1 part Esbilac powder and 2 parts water
Fox Valley offers skunk formula
Weaning regimen:
- Puppy food
- Humidified kibble for puppies
- Dry food for puppies
- Vegetables
- Eggs, scrambled or hard-boiled with shells
- Mouse
- Other natural diet foods.
Do not feed cat food to skunks. It is too high in fat and protein.
Natural food:
- Insects
- Rats, mice, moles
- To
- Snakes
- Bird eggs
- Grubs, slugs
- Bays
- Nuts
- Grasses, roots, cereals,
- Frogs
- Carrion
Release Criteria:
Release them at about 14 weeks, when they are almost full grown, before dusk. Choose a wooded area with lots of fallen rotten logs near a clean water source. Release them in family groups or with cage mates.
Special considerations:
Skunks have poor eyesight, but they have good hearing and a good sense of smell. They are particularly fond of making dens under buildings. The skunk’s white coat can be a good indicator of its health. Discoloration of the coat can be caused by a high parasite load or general poor health. Food, canned food, cereal, dried fruit or any food containing dyes (natural or artificial) can change the color of a skunk’s fur to pink, orange or yellow.
Skunks have a gentle and docile nature and will only spray if they are frightened, annoyed or surprised. If spraying occurs, the odor can be removed. There are many products on the market that work well and can be stored until you need them. Look for a product in a pet store or grain store that uses enzymes to neutralize odors. Enzymes destroy odor-causing bacteria.
The sprayed area should NOT be rinsed with water or washed with soap and water. This spreads the thiols (malodorous particles) around. Put your chosen odor neutralizer directly on each area that has been sprayed.
Vinegar, tomato juice or showers are somewhat effective, but they are not as effective as the home-made solution. For pets and humans who have been sprayed, the homemade solution works best. It can also be used on clothing.
In-house solution:
- One liter of 3% hydrogen peroxide
- ¼ cup baking soda
- 1 teaspoon of liquid detergent
Be careful not to get it in your eyes, nose and mouth, even if they have been sprayed.
Mix the ingredients together and use it right away. It decomposes quickly and loses its power. The peroxide in the recipe will bleach some fabrics, fur and hair.
Health problems:
Skunks frequently carry internal and external parasites. Common external parasites are fleas, ticks and lice. An internal parasite is the baylisascaris columnaris (the common large roundworm of the skunk). Deworm on admission as soon as they are stable (from 2 weeks of age) and repeat every month until release.
Tapeworms, flukes, guinea worms, stomach worms, lung worms and coccidia are also common internal parasites in skunks.
Skunks are susceptible to rabies, distemper and parvo. They must be vaccinated against diseases, distemper, canine parvo and feline parvo.
***Confirm the information below with your veterinarian.
Foxes belong to the canidae family. They are hunters like cats and have semi-retractable claws. It is the female who mainly raises the young, but the male will bring food to the den. The other females in the family act as guardians when the fox leaves the den to find food and water.
Gestation

Roux : 52 days
Birth
March – April
Litter size
About 2 to 7. They usually have one litter per season.
Period of activity
Nocturnal and twilight
Habitat
They can be found almost everywhere. Although they prefer forests and mixed fields, they adapt easily to neighborhoods. Red and gray foxes share many similarities but are genetically different. These differences are important for rehabilitators and for the proper choice of housing, diet and health issues.

Birth at 1 week |
Red: the average weight is 100 to 120 grams. They are born with their eyes and ears closed and their fur is gray, charcoal colored. They are unable to thermoregulate the first two weeks, thus providing heat. Feed formula every 2 to 2.5 hrs and at least once a night. |
Grey: Average birth weight 3 ounces or 85 grams. They have a nice coat of fur and dark pigmented skin. They are blind and deaf. Provide heat and feed every 2.5 hours, at least once a night. |
1 week |
Feed with formula every 2.5 hrs. Night feeding can be eliminated if the baby is healthy and gaining weight. |
Feed formula every 2.5 hours. Night feeding can be eliminated if the baby is healthy and gaining weight. |
2 weeks |
The eyes open and are milky blue. Their vision is not clear at this point. The fur turns dark brown and their baby teeth start to grow. Give the formula every 3 to 4 hours. They should now be housed in a very large dog carrier with a dog house and toys. |
At 10-14 days, their eyes open. They have a woolly coat with red highlights. Give the formula every 4 hours. Offer wet kitten food and pour formula on top. |
3 weeks |
Start introducing water and solid weaning foods into their nest. They will try to walk. Place “surprises” in the cage such as treats and toys. Give formula 5 times a day by bottle or in a bowl. |
The vixen begins to bring food to the den. At 3 to 5 weeks of age, the teeth appear. Introduce solid foods. Offer the formula 3-4 times a day. |
4 weeks |
They weigh about 600 gr. They are ready for the pre-release cage. Babies play together but may fight to establish a dominance hierarchy. This is normal behavior. Offer a wide variety of weaning foods as well as foods from their natural diet. Set up multiple feeding locations to ensure that babies at the bottom of the hierarchy get their share of food. Offer the formula 4 times a day. |
In the wild, babies begin to learn to hunt. Offer a variety of weaning foods as well as their natural diet. |
5 weeks |
The fawn colored fur appears. They begin to venture out of the nesting area to play. Offer the formula 2-3 times a day. Slowly decrease the number of formula feedings over the next few weeks and continue to offer a mixture of weaning foods and natural diet. They hide food. |
They leave the den for a short period each day with the mother. Offer the formula 1-2 times a day. |
6 weeks |
They weigh about 2.2 pounds. |
|
8-10 weeks |
They should be completely weaned and eating a wide selection of weaning and natural diet foods. They will have their adult color. Their characteristics will have changed; their snout becomes longer and their ears become long and pointed. |
They should be weaned by 8-9 weeks. Hide the food in their cage so they have to “hunt” for it. |
14 weeks |
Their adult teeth are starting to come out. In the wild, they would start hunting. Hide the food in their cage so they have to “hunt” for it. |
In the wild, at 16 weeks, they are independent. |
5-6 months |
Release at 6 months if all behaviors are appropriate and they are uncomfortable with humans and dogs. They weigh 3.5 kg or more. |
Release at 5 months. |
Meeting Strategies
When babies start playing outside the den, people often make the mistake of thinking they are orphans. The fox may be hunting, leaving them unattended. At this age, babies are not afraid of humans, which increases the likelihood of them being kidnapped. If the mother has been killed and the babies are very young, injured, sick or hungry, they must be brought in for rehabilitation.
Older babies can be monitored and fed until they develop better hunting skills. If they are already weaned, their father or an older female family member can successfully adopt them.
Weaning diet
- Puppy kibble
- Cat food (young foxes need taurine in their diet)
- Fruit
- Bays
- Hazelnuts
- Sweet potato
- Eggs, scrambled or hard-boiled
- Ground turkey with bones also ground.
- Earthworms, mealworms, crickets
- Mice, rats, other small mammals
- Grass, earth
- Soup bone
- The chicken pieces, which were seared in boiling water for 1 minute to kill the bacteria, provide the foxes with food similar to what they would catch in the wild. Longer cooking times may weaken the bones and present a danger to the animal.
Natural diet (foxes are omnivores although they are classified as carnivores)
- Mainly mice, moles and voles
- Rabbits, squirrels and other small mammals
- Birds
- Turtles
- Fresh carrion
- Eggs
- Fruits, berries of wild mammals
- Seeds, corn, herbs
- Insects (crickets, grasshoppers, moths, etc.)
Release criteria
Five months for grey foxes and six months for red foxes. Release foxes in mid to late summer, late in the day. They must fear humans and domestic dogs. The ideal release location is away from roads and without the presence of coyotes. Grey foxes prefer wooded and swampy areas.
Special considerations
Do not raise a baby fox alone! Foxes are social and must be raised with other foxes.
Grey foxes are very good climbers and need climbing training in their pre-release cage. Red foxes also climb but are not as skilled. Provide niches, high shelves, places to hide in the bush, hollow logs and large grass stems, also add toys (stuffed animals, etc..) in their pre-release cage.
Hang a stuffed animal on a thick rope within reach of the puppies. Foxes love to dig. Make the cage floor with a deep layer of dirt and leaf litter, or provide them with a large box of soil or sand to dig in. Provide plenty of space to develop their motor skills. Offer clumps of fresh grass with the ball of dirt attached. Once the foxes are weaned, there should be minimal human contact. A fox that is not afraid of humans and dogs will have a very short life span.
Do not put red and grey foxes together. Greys are the most aggressive and do not tolerate red foxes in their territories.
Grey foxes start breeding at 10 months and are monogamous. Adult couples stay together and raise the young.
Health problem
ROUX |
GREY |
Canine distemper. Vaccinate to prevent this disease. Redheads are resistant to distemper and parvo. Vaccination is recommended. Vaccinations are usually given in 3 doses at the following intervals: 8-10, 12-16 and 18-20 weeks. Duramune 6 Way® by Boehringer Ingelheim is a recommended vaccine.
|
Very sensitive to canine distemper. Do not use modified vaccines with gray foxes, as this can kill them or cause permanent damage to the central nervous system. ***Boehringer Ingleheim / Merial Recombitek or Merial Purevax® Ferret Distemper vaccine can be used safely. |
Very sensitive to sarcoptic mites (sarcoptic mange). Easily cured with ivermectin. |
Resistant to sarcoptics |
Health problem for both |
|
Use precautions for rabies vector species. (RVS) Get vaccinated to prevent rabies. Rabvac 3 or Imrab 3 rages at 12 weeks. Vaccinate them as soon as possible, as foxes may become too wild to handle after weaning. |
|
Ascariasis. Dewormed on admission (as soon as stable) then repeat every 10-14 days thereafter until release. |
|
Tapeworms. If fox babies are admitted with fleas, treat them for tapeworm. Animals also get tapeworms (Taenia and Dipylidium) by eating rodents and rabbits. |
|
Heartworm – Revolution® is a topical product. One application lasts one month and offers protection against heartworm and treats scabies. |
|
Congenital Hydrocephalus: This condition is thought to be caused by a virus transmitted in the womb. Symptoms may include: a domed head (not apparent in older foxes) caused by swelling in the brain, soft spots (fontanelles) on the head that do not close, head tilt, blindness or protrusion of the eyes, bags under the eyes, vocalizations, difficulty walking, circling, self-mutilation or convulsions. Be careful when rehydrating. Symptoms may wax and wane. This condition is incurable and is painful for the animal. X-rays of the head can confirm the diagnosis. Euthanasia is a humane decision in this case. |
|
Foxes often enter shelters because they or their parents have been hit by cars, caught in traps or shot. |
Vaccination
The recombinant distemper vaccine, according to Merials studies published in 2003, is the only product that should be used in exotic and wild species. It provides protection 4 hours after administration. Even one dose of vaccine offers protection against distemper.
***Confirm the information below with your veterinarian.
Period of activity: Nocturnal
Habitat : They prefer woods and an easy source of water.
Note on parasites: Opossums can be heavily infested with parasites, especially ectoparasites such as fleas. It is important to remove fleas from the possum or potentially fatal anemia and death may occur. This is especially critical in young opossums. Fleas can be safely removed by wrapping the possum in a warm towel and allowing the fleas to jump from the possum to the towel. Replace them with hot towels as needed until the fleas are gone. Immediate flea treatment is not recommended as it can cause shock and death to an already weakened possum.
Age Indices: Appearance and Behavior
Birth at 1 week: At birth, baby Virginia opossums are naked and blind and are about the size of a bee. They are essentially, as naturalist writer Ted Williams notes, walking embryos. Immediately after birth, they must use their small but strong front legs to climb into the mother’s pouch.
The mother opossum licks the pouch and other hairs to help the baby opossums on their journey. Many don’t make it. Once in the pouch, life doesn’t get any easier. An opossum litter may consist of 25 pups, but a female has only 13 nipples, not all of which can provide milk. If the possum does not attach to a functional nipple, it dies.
The lucky survivors remain attached for 50 to 70 days. After that, they can stay in the mother’s den or ride on her back. After about 120 days, they leave to live the life of a solitary possum, a transition that 60% do not survive. The birth weight is about 0.2 g. Feeding at this age is difficult and sometimes impossible.
2 weeks: They are still tiny, almost embryonic, with pink skin, no fur and with closed eyes and mouth. They weigh about 2 grams. It is difficult to insert a feeding tool into their oral cleft. The sexes can now be distinguished. Mothering every 2 hours with 2 night feedings. Feed a diluted formula of 1 part formula to 5 parts water. They do best in an incubator environment with a temperature of 90-95 with added humidity of about 65-75%. This provides similar conditions to the mother’s pouch.
3 weeks: They weigh about 18 grams. Their hind legs and tail become functional and the ears begin to open. Babies make a sneezing sound when they are hungry or looking for mom. Continue to feed the formula every 2 hours. Eliminate night feeding, but start feeding early in the day and continue feeding late into the night.
4 weeks: Their weight is about 28 grams. They start to show the first signs of skin pigmentation and fur growth. They will cry out loud when they are upset. The tail is able to form a loop. Feed the formula every 2 hours. Eliminate night feedings.
5 weeks: The whiskers start to grow around the mouth. Mother’s food every 2h30.
6-7 weeks old: Fur begins to grow on neck and back. Mothered feeding every 2 ½ to 3 hours.
8-9 weeks: The weight can be about 40 grams. Their eyes are now open. In nature, babies are able to leave the pouch for short periods of time. In rehabilitation, they will move around in the incubator box and become restless. Feed the formula every 3-4 hours.
10 weeks: They weigh 45-50 grams. Babies will begin to thermoregulate, but will not yet be effective. Offer them a mixture of formula and cat food mixed to the consistency of pudding. To encourage babies to start eating solids, pour formula over ripe bananas in a shallow lid or offer half a grape to start the weaning process. Provide fresh formula in a clean lid every three to four hours. At this point, they will have some of their food on them, but they will clean themselves and each other. Check their weight every day or two to make sure they are gaining weight. Syringe feeding formula every 4 hours to “top up” babies who are not eating enough on their own or not gaining weight. Also provide shallow lids of fresh water or water bottles. They start to crawl around the cage. They will be able to urinate and defecate on their own and will use a litter box if provided.
11 weeks: They can weigh about 70 grams. Babies have teeth and can chew small pieces of solid food. Start introducing basic diet foods. Offer a mixture of cat food and chopped vegetables/fruits. At this cage they can be moved from the incubator to an indoor cage in height. Provide a heat source in the nest area until they no longer need it. They are able to run and hide at this age. Clean the feeding area regularly.
12 weeks: Weaning is almost complete. Offer a wide variety of foods in addition to their mix. The possums will emit a “click” to communicate. Introduce the crickets as live food.
13-14 weeks: Leave a dish of adult cat food out at all times. They will need more space to exercise. Move them to a larger outdoor cage and provide logs and branches to climb on, exercise wheels, tunnels and leaves for the bottom of the cage. They now have their 50 teeth and are completely weaned. At this age, they are able to thermoregulate effectively.
15 weeks: Physical and behavioral development becomes rapid. They are able to make grunts. They are ready to be released.
Food:
In the rehabilitation situation, tube feeding is by far the most effective and practical method of feeding formula or rehydration fluid to a baby possum.
You will need to learn how to do this from your veterinarian or an experienced rehabilitator. If you feel this is something you are not comfortable doing, you can also feed them with a syringe with a small extended nipple or a #3 1/2 French or #5 French feeding tube. Place the nipple towards the back of the baby’s throat and slowly pour the formula into the baby’s mouth. This will take much longer than the tube method, but it is another option. Tiny babies may need to be fed every hour or two (including overnight) with a diluted formula.
or you can watch this video (tube feeding) How to feed baby possum with tube
Formula:
Start with rehydration for 4 hours (see treating a dehydrated baby) then switch to a very weak formula. Gradually increase the strength of the formula over a period of three to four days. The Opossum Company of the United States recommends Singpox Vailey Day 1 formulas. The National Opossum Society recommends a much more complicated formula similar to the one printed below. Please research other formulas to see what has worked well for the opossum in your area.
Formula for babies up to 3 weeks old or less than 25 g.
- 1 volume of Esbilac
- 5 volumes of water.
- or use Fox Valley Day One 32/40 up to 45 grams
Gradually switch them to the formula below or use Fox Valley Day One 25/30 for babies from 45 grams to weaning
Formula for babies over 3 weeks old and over 25 g.
- 1/3 cup Multi-Lait® powder
- 1 cup of water
- ½ hard-boiled yolk from a large egg
- 1 teaspoon of liquid Neo-calglucon
- ½ tablet of a 7.5 grain nutritional brewer’s yeast tablet (also available in powder)
- 1.5 teaspoons of apple juice
Weaning diet: less than 450 grams
They are still receiving about 10% formula. The diet should include 10-15% fruit and 40% vegetables. At less than 450 grams, cat food is the main source of protein and this is considered sufficient. Do not give more protein at this age. Too much protein can cause an imbalance in the calcium-phosphorus ratio, which can lead to metabolic bone disease.
The Opossum Society of the United States (OSUS ) recommends one part good quality cat food to one part fruit and vegetable mix with ¼ teaspoon of calcium carbonate (Caltrate tablets).
Weaning diet over 450 grams
Discontinue providing formula. Add 10% protein to the above diet, in the form of eggs with shells, chicken, sardines. When offering protein foods, always offer a source of calcium as well, such as eggs with shells, chicken with bones (steamed for 1-5 minutes) or sardines with bones or some crickets.
Natural diet : Omnivore
- Insects
- Fruits
- Invertebrates
- Eggs
- Rodents
- Litter of leaves and logs
- Small mammals
- Carrion
Special considerations:
Feigning death is probably the most creative and risky trick that animals have developed to escape their predators.
This behavior, which is called thanatosis or mock death, is present in the entire animal kingdom, from birds to mammals and fish. The Virginia opossum, in the United States, is probably the most famous imposter. It opens its mouth, sticks out its tongue, empties its intestines and expels foul-smelling fluids to convince its predator that it is no longer good to eat.
Other interesting facts about the possum:
Possums have a bad reputation as garage invaders and “scary” animals that roam our porches at night. They’re not the cutest, in fact, some go so far as to call them ugly. The reality is that possums are incredibly useful and generally misunderstood. Here are some fascinating facts about opossums (and yes, the “o” is silent) that will make you think twice before chasing them out of your yard!
- A picture of a possum playing dead doesn’t really do it justice. To fully enjoy the experience, you must stand to smell the putrid odor he gives off when he poses as a corpse. The foul-smelling substance it secretes from its anus is just one more reason for foxes and bobcats to seek their dinner elsewhere.
- Opossums have impressive memories, at least when it comes to food. Researchers found that opossums remember the trail that led to a tasty treat better than rats, cats, dogs and pigs. They can also remember the smell of toxic substances up to a year after trying them.
- Although opossums are not completely immune to rabies (a few cases have been documented), finding a specimen with the disease is extremely unlikely. Marsupials such as opossums have a lower body temperature than the placental mammals that dominate North America – in other words, their bodies do not provide a suitable environment for the virus.
- You may have seen the headlines: possums fight Lyme disease! In one season, an opossum can kill about 5,000 ticks. See the original study

Gestation
The active pregnancy is about 17 to 23 days.
Birth
April or May
Litter size
About 6 small
Period of activity
Day and night
Habitat
Forests, scrubby fields, near stone walls. They favor abandoned squirrel burrows and tree hollows.
Birth |
They weigh 11 oz. They are born blind, with tiny closed ears and no teeth. The birth weight is about 1 to 4 grams. They are noisy and vocalize a lot. The color of the coat changes with the seasons. In winter, the long-tailed weasel is all white except for the tip of the tail which is black. In summer, the whole body is brown, except for the belly, the tip of the snout and the inner side of the legs. They have well developed claws. They have a strong sucking instinct. Give formula every ½ hour, including night feeds. Make sure they gain weight. Their metabolism is very fast, so they need to eat often. |
1 week |
Keep them warm (hot pad) or they will be cold to the touch. Their pulse and metabolism slow down. This can be reversed with a slow warm-up. Feed the formula every hour and several times during the night. |
2 weeks |
The coat will be covered with silky white hair. Feed every 1 1/2 hrs and min. ten times a day. |
3 weeks |
They are fully hairy and can crawl. Feed formula every 2 hours. Offer solid food in the cage, as they start to nibble before their eyes even open. |
4 weeks |
Their teeth are growing and they can eat solid food. Their eyes begin to open. Offer softened kitten food and mice cut into small pieces. Bring a bowl of water. They should be in a metal cage with plenty of room to play. Offer the formula in a shallow bowl and refresh it often. |
5 weeks |
The eyes are open. They are very playful and like tubes and hollow logs to hide in. They like the rodent wheels. Make sure there is enough food at all times. |
6 weeks |
Feed a mixture of soaked and dry kitten food. Also offer small dead prey. At 6 to 7 weeks of age, mink are weaned and ready to stalk on their own. |
7 to 8 weeks |
Feed soft, hard kitten food and dead prey. Place them outside in a pre-release cage. Furnish the cage with logs, branches, tunnels and soil. |
Release |
From 5 months . |
Meeting
They are animals that like to dig and their nests are underground. Meeting is rarely an option. The babies will remain under the ground unless the mother returns to feed them. All babies found above ground will need help.
Formula
1 part Esbilac powder, 1 part KMR and three parts water (KMR includes taurine, which provides important nutrition for carnivores. It plays a role in the development of the heart, eyes and reproductive system). Fox Valley also hold a formula for them.
Weaning diet
- Canned cat food or dry kibble
- Boil the chicken wings briefly for about two minutes to destroy any surface bacteria. Cooking longer makes the bones brittle and is dangerous for the baby.
- Crickets
- Flour worms
Natural Diet
Mice and field mice, small mammals, birds, eggs, insects.
