Medical Conditions

  • Obesity is a major problem in older birds on seed-based diets and can contribute to diseases such as arteriosclerosis, atherosclerosis (fat deposits in major arteries), and fatty liver disease (hepatic lipidosis). Unlike their wild counterparts, pet birds are not given as much opportunity for daily exercise. Pet birds often burn off very few calories in their daily lives. Switching a bird from an all-seed diet to a more suitable diet consisting mainly of pellets, with smaller amounts of fresh vegetables and fruit, will decrease its overall daily intake of calories.

  • Polyfolliculosis is a condition in which several feathers grow out of one feather follicle. These feathers may be irritating, causing the bird to pick at them or pluck them out. There is no specific treatment for this condition.

  • Avian polyomavirus infection (APV) can cause benign feather lesions in budgies, slow crop emptying in newly weaned parrots, hemorrhages on the skin, or acute death. Clinical signs, diagnostic testing, and preventive measures are explained in this handout.

  • The most common conditions affecting pet prairie dogs are: obesity, dental problems, cardiac disease and intestinal parasites. Regular scheduled veterinary examinations will be of great benefit to help discover problems or diseases before they cause a critical illness.

  • A telemedicine visit is typically conducted over telephone, text messaging, chat, email, or videoconference. This may allow a veterinarian to diagnose and treat your pet’s medical condition remotely, without the need for an in-person visit. Your appointment will be conducted by a licensed veterinarian.

  • Proventricular dilatation disease (PDD) is a very serious and often deadly disease affecting a wide variety of parrot species. Symptoms often involve one of the following conditions; vomiting, weight loss, passing undigested seeds in the stool or show neurologic signs. Avian Bornavirus infection has been linked in some cases to PDD.

  • Psittacine beak and feather disease (PBFD) is a serious condition in parrot species for which there is no cure. The highly contagious virus attacks fast-growing epithelial cells, commonly causing visibly abnormal formations of the beak and/or feather follicles. The clinical signs vary depending on the species of bird and the age at which it was infected. Diagnostic testing is available and precautions must be taken when purchasing a new bird.

  • In the wild, a bird will try to uphold a strong appearance when sick. By the time a pet bird begins to display symptoms of illness, it has likely been sick for several days to weeks. Many things contribute to ill health. This handout provides bird owners with a list of signs that will alert them that their bird is sick.

  • 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.

  • Dystocia means difficulty giving birth or abnormal delivery. In reptiles that do not give live birth, dystocia may also be called egg binding or ovostasis. It is a relatively common problem in reptiles, and can be life-threatening. Any signs of abdominal swelling need attention.
