Pancreatitis

Inflammation of the pancreas, a hard-to-spot illness in cats that often causes only tiredness and loss of appetite.

Also called: feline pancreatitis, inflamed pancreas, fPL test

The pancreas is a small organ near the stomach that makes digestive enzymes and insulin. In pancreatitis it becomes inflamed. The cause is usually unknown. In cats the problem is often long-lasting and mild, though sudden, severe attacks occur.

Unlike dogs, cats often do not vomit much. The signs are vague: tiredness, hiding, loss of appetite, weight loss, dehydration, low body temperature and sometimes belly pain, vomiting or diarrhea. The illness often occurs together with inflammatory bowel disease and disease of the liver or bile ducts, a combination vets call triaditis. It may also be linked to diabetes mellitus.

No single test is perfect. Vets combine the exam, blood work, a specific blood test for pancreatic enzymes, and an ultrasound scan. Treatment is supportive and tailored to each cat: fluids, pain relief, anti-nausea medicine and getting the cat to eat. A cat that refuses food needs nutrition, since going without can lead to hepatic lipidosis, a liver disease. Do not give human medicines or force-feed without guidance. Any cat that has not eaten for a day or is lethargic should see a vet. Ask your vet about long-term diet and checks.
