Pancreatitis in Cats: Recognising and Managing a Painful Condition

Feline pancreatitis — inflammation of the pancreas — is more common than previously recognised and can cause significant pain and metabolic disruption. Unlike dogs, cats rarely show classic signs, making diagnosis challenging.

Key Facts

Feline pancreatitis involves acute or chronic inflammation of the pancreatic tissue
Prevalence in the general cat population may be as high as 40–67% based on post-mortem histopathological studies
Unlike dogs, cats with pancreatitis rarely vomit prominently — signs are often subtle: lethargy, reduced appetite, and weight loss
Feline pancreatitis is frequently associated with concurrent triaditis — simultaneous pancreatitis, cholangitis, and inflammatory bowel disease
Diagnosis uses serum feline pancreatic lipase immunoreactivity (fPLI) and abdominal ultrasound
Treatment is primarily supportive: fluid therapy, anti-nausea medication, pain management, and nutritional support
Early and adequate analgesia is critical — pain is a primary driver of anorexia and clinical deterioration in affected cats
Chronic low-grade pancreatitis may contribute to the development of diabetes mellitus and exocrine pancreatic insufficiency over time

Welfare Considerations

Pancreatitis is a genuinely painful condition. The inflamed pancreas causes abdominal pain that in cats often manifests as hiding, hunched posture, reluctance to be handled, and complete loss of appetite. Because cats mask illness and do not vocalise pain reliably, many cases go unrecognised or are attributed to vague malaise. The association with triaditis means multiple organ systems may be simultaneously inflamed, compounding suffering. Adequate pain management — often underused in feline medicine historically — is now recognised as essential both for welfare and for improving recovery, since pain-related anorexia in cats rapidly leads to hepatic lipidosis. Prompt diagnosis and multimodal analgesia are the most impactful welfare interventions.

What You Can Do

Seek immediate veterinary attention for any cat that stops eating for more than 24–48 hours
Request fPLI testing and abdominal ultrasound if pancreatitis is suspected in a lethargic, anorexic cat
Ensure your vet provides adequate analgesia — do not accept "wait and see" without pain management for suspected pancreatitis
Ask about concurrent disease testing (liver enzymes, cobalamin, B12) given the frequency of triaditis
Follow up with dietary recommendations — low-fat, highly digestible food may reduce recurrence risk in some cats
