Pancreatitis—inflammation of the pancreas—is a significant cause of illness and welfare compromise in cats. Unlike dogs, feline pancreatitis is often chronic, subtle in presentation, and commonly occurs alongside other conditions. Recognition and management are critical to cat welfare.
Cats frequently develop a triad of concurrent conditions: pancreatitis, inflammatory bowel disease (IBD), and cholangitis (liver/bile duct inflammation), collectively termed "triaditis." This makes diagnosis complex, as each condition can mask or exacerbate the others. The aetiology is often unknown in cats—unlike dogs, dietary fat overload is rarely implicated.
Feline pancreatitis often presents subtly: lethargy, reduced appetite, weight loss, vomiting, and abdominal pain. Jaundice may indicate concurrent liver involvement. Acute severe pancreatitis can cause collapse, hypothermia, and rapid deterioration. Many cats have chronic low-grade disease detected incidentally during investigation of other conditions.
fPLI (feline pancreatic lipase immunoreactivity) testing, including the Spec fPL test, is the most sensitive serum marker for feline pancreatitis. Abdominal ultrasound can confirm pancreatic changes but requires experienced interpretation. Histopathology of pancreatic tissue provides definitive diagnosis but is rarely pursued in clinical practice. Bloodwork may show elevated liver enzymes, bilirubin, and non-specific inflammatory markers.
There is no specific cure; treatment is supportive. Fluid therapy addresses dehydration. Anti-nausea medications (maropitant, ondansetron) control vomiting. Pain management with opioids or buprenorphine is essential—cats mask pain but are certainly suffering. Nutritional support is critical: enteral feeding via nasogastric or oesophagostomy tubes maintains gut function when cats refuse food voluntarily.
Early nutritional support improves outcomes. Contrary to historical "pancreatic rest" protocols, withholding food is no longer recommended. Cats with concurrent IBD may benefit from hydrolysed or novel protein diets. Long-term dietary management varies by individual comorbidities. Feeding little and often may reduce pancreatic stimulation in some cats.
Chronic feline pancreatitis requires ongoing monitoring and management. Cobalamin (vitamin B12) supplementation is often necessary, as pancreatitis impairs absorption. Ursodeoxycholic acid supports concurrent cholangitis. Prednisolone may be prescribed for concurrent IBD. Regular monitoring of bodyweight, appetite, and periodic fPLI testing guides long-term management.
Chronic pancreatitis causes ongoing discomfort, reduced quality of life, and cumulative welfare compromise if undertreated. Recognition of subtle pain signs in cats—hiding, reduced grooming, hunched posture, reluctance to interact—is essential. Veterinary pain assessment tools for cats help quantify suffering and guide treatment intensity.
