Chronic Diarrhea in Cats

Cats that suffer from diarrhea for more than 3-4 weeks are considered chronic. The most common causes include:
• parasites – worms, protozoa, giardia
• inflammatory bowel disease
• adverse food reactions
• cancer
• viral infections
• antibiotic-related
• organ failure (liver, kidney)
• thyroid problems
• pancreas problems

Cats with chronic diarrhea should undergo a comprehensive workup at the vet hospital. The vet will usually want a fresh stool sample to check for parasites. Blood test will determine whether there are any liver, kidney or thyroid problems.
