Caring for a sick ferret can be a scary, challenging, and rewarding experience. Whether it is a cold or a life threatening illness, ferrets really benefit from constant attention and love. It is imperative that you contact or take your ferret to a veterinarian any time it is sick. What may start out as a simple cold or flu could turn into pneumonia or dehydration.
Be sure to check with your veterinarian before administering any "over the counter" pet store or human medications. For example, aspirin and other human pain medications can be lethal to a ferret. Human cough or cold medications can also kill or make your ferret very sick if they contain certain ingredients or are given in incorrect dosages. Your veterinarian can tell you which medications are safe and the correct dosages to give. Don't put your ferret's life in jeopardy to save time or money. Below I have listed some tips I have used in caring for ferrets who were recovering from an illness. I am assuming that your ferret has already been to the veterinarian for diagnosis.
Keep your ferret warm, comfortable and caged separately from any other ferrets. If your ferret has a contagious virus, any other ferrets you own could catch it as well. Wash all communal toys and bedding to avoid spreading the virus. You should always have an extra cage available in case separation is needed. Ferrets who are recovering from surgery should also be caged separately to avoid ripping or snagging the stitches during play. Most ferrets want quiet time when they are ill (except for your pampering). Keeping them caged during an illness makes keeping an eye on them a lot easier as well. A sick ferret may curl up under a piece of furniture or under a cabinet for privacy, making it very hard to find them. Make sure your ferret has something warm to snuggle up in as well. Do not place your ferret on a heating pad.
Make sure your ferret stays hydrated. You can tell if your ferret is dehydrated by pulling up the skin on the "scruff" area of the neck and letting the skin fall. If the skin doesn't snap back into place, or takes a long time to snap back, you ferret is probably dehydrated (older ferrets tend to have skin that may naturally snap back slowly. Get to know the normal skin behavior of your ferret.). You can also feel your ferret's tongue and gums to see if they are lacking moisture. Often, ferrets will act disoriented and lethargic if dehydrated. If you suspect your ferret is dehydrated, please take it to a veterinarian. Once a ferret is very dehydrated he or she can not drink enough water to solve the problem. Intravenous or under the skin fluid injections are often needed. Just a few bouts of vomiting or diarrhea can cause dehydration.
Make sure your ferret is taking in food. If your ferret is recovering from an intestinal virus, low blood sugar, surgery or other disease, he or she may not be eating enough to maintain body weight. If your ferret is refusing to eat on it's own, you may need to hand feed prescription diet canned food or a suitable replacement.
