Feline pancreatitis is far more common than previously thought -- studies show 45-67% of cats have evidence of pancreatitis at necropsy. Yet it remains one of the hardest conditions to diagnose in living cats because symptoms are vague and subtle.

What Is Pancreatitis?
- Inflammation of the pancreas -- the organ that produces digestive enzymes and insulin
- Digestive enzymes activate prematurely, damaging the pancreas itself
- Can be acute (sudden, severe) or chronic (low-grade, ongoing)
- Chronic pancreatitis is most common in cats and often goes undiagnosed
Symptoms
- Lethargy: Less active, sleeping more (the most common sign)
- Decreased appetite: Eating less or refusing food
- Hiding: Withdrawal from family interaction
- Vomiting: Less common in cats than dogs with pancreatitis
- Weight loss: Gradual
- Abdominal pain: May hunch over, resist being picked up
The Triaditis Connection
In cats, pancreatitis frequently occurs simultaneously with two other conditions:
- IBD (Inflammatory Bowel Disease)
- Cholangitis (liver/bile duct inflammation)
- This triad is called "triaditis" and occurs because the pancreatic duct and bile duct share a common opening in cats
- Inflammation in one organ easily spreads to the others
- Treatment must address all three conditions simultaneously
Diagnosis
- fPLI (Spec fPL): Blood test specific for pancreatic inflammation -- most reliable non-invasive test
- Ultrasound: Can show pancreatic enlargement and inflammation but not always visible
- Biopsy: Definitive but requires surgery or laparoscopy
- General bloodwork: May show elevated liver values (triaditis) but pancreatic values often normal
Treatment
- IV fluids: Rehydration and electrolyte support
- Anti-nausea: Maropitant (Cerenia) -- essential for comfort
- Pain management: Buprenorphine or gabapentin
- Nutritional support: Feed as soon as possible (do NOT fast cats with pancreatitis)
- Treat underlying cause: IBD management, cholangitis treatment if triaditis present
- B12 supplementation: Cobalamin often depleted in pancreatic/GI disease
Frequently Asked Questions
Can pancreatitis be prevented?
No reliable prevention exists because the cause in cats is usually unknown (unlike dogs where high-fat meals trigger episodes). Maintaining a healthy weight, feeding a consistent moderate-fat diet, and managing concurrent conditions (IBD, liver disease) may reduce recurrence risk. Cats with one episode are at higher risk for future episodes -- monitoring for subtle symptom return is important.
