Like any animal, ferrets can become sick or suffer from poor health. While
your veterinarian is the most qualified to help diagnose disease or
illness, here are some things to look for in a healthy ferret:
Ferrets are susceptible to canine distemper, a viral disease that usually causes anorexia, snotty nose, rashes, and footpad swelling followed by death. Vaccinate kits 3 times and follow-up with annual boosters to prevent.
Rabies Ferrets are susceptible to rabies if they are around other infected animals. Rabies is a very serious infection that can cause death in man and animal. Yearly vaccination with a ferret-approved vaccine is recommended.
Ferrets are not as likely to get internal parasites as dogs and cats, but have their stool checked by your veterinarian yearly. External parasites (fleas, ticks, ear mites) are more common if your ferret is around dogs and cats or spends time outdoors.
Bone Marrow Suppression
Intact (not neutered or spayed) female ferrets can enter into a prolonged heat, which causes death in over 75% of females not bred. The easiest way to prevent this is to spay females not intended for breeding.
Insulinomas are the most common tumors of middle to old aged ferrets (4-5 years). These tumors result in low blood sugar, and ferrets with this type of tumor may faint or collapse, may appear drugged with glassy eyes, or just appear very weak over time. Your veterinarian can diagnose this disease with blood tests. It is treatable with medicine or surgery.
Adrenal Gland Disease
Adrenal gland disease is another common disease of older ferrets and is characterized by progressive hair loss. Sometimes the ferret will go almost bald, then grow hair back and lose it again. The ferret may also appear itchy. It is not easily diagnosed in the ferret as it is in dogs and cats. Surgery is the preferred treatment method, but medical management is available.
Ferrets can have diarrhea from a variety of sources, including bacteria, viruses, and improper foods. Never give your ferret raw meats or eggs. Avoid milk and milk products, as well as foods high in sugar and carbohydrates. Ferretone should be limited.
Colds and Flu
Ferrets can actually catch a cold or flu from their owners! The symptoms are similar to people with sneezing and upper respiratory sings. Although these usually resolve without medical treatment in several days, infections in ferrets can become serious fairly quickly--especially if they become dehydrated. Ferrets are small, and diarrhea and vomiting can cause dehydration before you know it.
Tender loving care, rest, warmth, and plenty of fluids are essential during this time (you can even try chicken and duck soup!) But, if your ferret is not consuming a lot of liquid, or you have any questions about home remedies, it might be best to consult a ferret veterinarian within the first couple of days.
