The majority of cat diarrhea resolves on its own within a few hours or days without medical attention. Diarrhea in felines can be caused by several reasons, such as a change in nutrition, parasites, stress, or an intestinal infection.
Consult your veterinarian if diarrhea in your cat persists for more than a day. The vet will undertake physical examination of your cat, as well as laboratory tests, or endoscopy or biopsy if needed.
