Pancreatitis is the most common disease of the exocrine pancreas in cats, but it is hard to diagnose: the signs are vague, the blood tests are imperfect, and many cases are low-grade and chronic. It often occurs together with inflammatory bowel disease and cholangitis, and the most dangerous complication of a few days without eating is hepatic lipidosis.

Key facts

  • Species and system: cat; digestive system (exocrine pancreas).
  • Cause: in most cats (over 95% according to the ACVIM consensus) no cause is found.
  • Forms: acute necrotizing, acute suppurative and chronic (lymphocytic) pancreatitis; chronic disease is far more common at necropsy.
  • Classic presentation: lethargy and poor appetite, sometimes with dehydration, hypothermia, vomiting or icterus; abdominal pain is often not obvious.
