Chinchillas are naturally healthy. With proper nutrition and care, illness is rare. The main causes of illness are poor genetics and improper husbandry. Chinchilla owners should be aware of the most common illnesses to provide timely assistance.
How to tell if a chinchilla is sick
A healthy pet is active and eats well. The main signs of illness in chinchillas are:
- loss of appetite, lethargy;
- discharge from the nose, eyes;
- bowel movements, mucus and blood in the stool;
- dullness of the coat, its loss;
- sudden weight loss or gain.
If one or more of these symptoms appear, consult a doctor: since the symptoms of many diseases are similar, self-treatment can be fatal. It's also important to take your chinchilla to the veterinarian as soon as possible because some chinchilla diseases are dangerous to humans.
