Rapid loss of more than 10 percent of a cat or dog’s body weight (not counting fluid loss) is considered a serious clinical condition, and should be brought to the attention of the veterinarian who monitors your pet’s health. By definition, cachexia is the state of extreme poor health from too much weight loss. Cachexia is often associated with anorexia, weakness, and mental depression. Besides being medical conditions themselves, cachexia and weight loss can be signs of other conditions that need attention. Inflammatory bowel disease, parasite infestation, organ failure, cancer, hyperthyroidism, diabetes, or even pregnancy can cause weight loss.
