About Feline Weight Loss

Unintended weight loss in cats is a clinical sign seen with various underlying causes

Asking the right questions can make the difference for the cats in your practice. While there are often subtle changes that the cat owner may or may not have noticed, early detection and action can help manage unintended weight loss while you diagnose the underlying cause.

Prolonged inadequate nutrition may be more detrimental to the patient than the underlying cause of their weight loss1

Therefore, both identifying weight loss and diagnosing the underlying cause are important. Once changes in eating behavior, body weight, and body condition have been identified and discussed with the cat owner, the tailored diagnostic investigation is initiated, guided by a thorough history and physical exam.

Some of the more common underlying diseases could be2-4

  • Hyperthyroidism

  • Chronic kidney disease

  • Inflammatory bowel disease

  • Neoplasia

  • Pancreatitis

  • Liver failure

Mirataz is indicated for the management of weight loss in cats.
