While less commonly seen than in their canine counterparts, cats can suffer from an excessive production of cortisol by the adrenal glands. 85% of the cases of feline hyperadrenocorticism are due to a pituitary tumor whereas 15% stem from an adrenal tumor. Progesterone-secreting adrenal tumors have been documented a handful of cats.
Diabetes mellitus (DM) is one of the most common endocrinopathies seen in cats. DM arises from a variety of pathophysiological causes. Causes of DM in cats include islet-specific amyloid deposition, chronic pancreatitis, obesity, infection, other illness, drugs, etc.
Feline bronchopulmonary disease (FBPD), often referred to as "feline asthma" actually encompasses a group of common, but poorly understood, airway diseases. It is estimated that bronchopulmonary disease affects 1% of the general cat population and > 5% of the Siamese breed. Cats of any age can be affected and there is no clear gender predisposition.
Diabetic ketoacidosis (DKA) is one of the most commonly encountered endocrine emergencies in small animal practice. DKA is typically seen in previously undiagnosed diabetics and less commonly occurs in patients that are on inadequate amounts of insulin.
Gastrointestinal disorders include some of the most common reasons why cats are presented for veterinary care. Diseases both within and outside of the gastrointestinal tract (GIT) affect the function of the GIT and can result in similar clinical signs.
Pancreatitis is being diagnosed more and more frequently in cats. Cats typically have chronic pancreatitis whereas dogs usually suffer acute disease. The difference in presentation between the species as well as a lack of appropriate diagnostic tools led to pancreatitis in cats being widely underdiagnosed.
