Ferrets have several unique problems; understanding these problems will allow you to better care for your pet and minimize future health care problems.
Guinea pigs are generally hardy, healthy animals but are susceptible to certain diseases. They cannot make their own vitamin C and require supplementation or they may develop scurvy. Guinea pigs get various tumors, particularly skin and mammary tumors. Guinea pigs also get abscesses (accumulations of pus and bacteria) in lymph nodes, skin, muscles, teeth, bones, and internal organs. They are very prone to development of urinary calculi that form in the bladder, kidneys, or ureters which may become lodged, causing a life-threatening obstruction. In addition, guinea pigs often are affected by ringworm and can get fleas and lice. Barbering is a problem, usually associated with boredom, in which the guinea pig chews or barbers its own hair or the hair of its cage-mate. Pododermatitis, or bumblefoot, in which sores develop on the bottom of the feet from pressure, is common in overweight animals housed on wire-bottomed or dirty cages that abrade the feet.
Rodents commonly develop certain health problems. Rabies is very unlikely in pet rodents (especially those housed inside, away from other animals). Many rodents barber their own hair or the hair of a cagemate as a result of stress in the form of overcrowding, fighting, or boredom. Foot necrosis is caused by fine fiber or thread nesting material wrapping around toes or feet and cutting off circulation. Guinea pigs cannot make their own vitamin C, so they must receive it as a supplement in their diets. All pet rodents, but especially guinea pigs and chinchillas, are very susceptible to life-threatening heat stroke from high ambient temperatures (greater than 80°F or 27°C). Certain antibiotics should never be used in rodents, as they upset the normal bacteria that live in rodents’ gastrointestinal tracts and favor toxin-producing bacteria that can be fatal to rodents. Chromodacryorrhea is seen in mice, gerbils, and most often in rats Diarrhea can have several different causes in rodents including infections with different bacteria, parasites, or viruses. Rodents also commonly get fractured bones from mishandling or falls, bacterial skin infections (dermatitis) on their faces, and may also experience seizures.
If you saw a person have a seizure or fall down the stairs or wreck a car, what would you do? You'd call 911. But what should you do when the crisis involves your pet? You call a pet emergency number. Ask your veterinary hospital how they handle after-hour emergencies.
Reproductive disease in ferrets is rare today, as most pet ferrets are spayed or neutered at a young age. One disease that is still occasionally seen in pet ferrets occurs in females that are not spayed. This is called hyperestrogenemia and is a result of persistently high blood levels of estrogen in unspayed females that are not bred or fails to ovulate.
