Weight Loss in Cats

Cats

Overview of Feline Weight Loss

Weight loss is a physical condition that results from a cat's negative caloric balance. This usually occurs when the cat's body uses and/or excretes essential nutrients faster than it can consume the. Essentially more calories are being burned than are being taken in. Weight loss is considered clinically important when it exceeds 10 percent of the normal body weight and is not associated with fluid loss.

In Cats, during weight loss, the appetite may be normal, increased or decreased.
