What Causes Pancreatitis in Cats?
📝 Summary
Feline pancreatitis is one of the most common cat illnesses, striking obese and senior cats most often and frequently traveling with bowel and bile-duct inflammation as a 'triaditis.' It starts when the pancreas digests itself through activated enzymes, and repeated vomiting with no food can slide into dangerous fatty liver, so veterinary care should not wait.
1 What Feline Pancreatitis Is
As the name says, it is inflammation of the pancreas — a common internal disease in cats, especially the overweight and the elderly. The pancreas makes the digestive enzymes the body needs to run, and it is the only source of lipase, which is why heavy-bodied cats are prone to it.
It rarely shows up alone. It often appears together with inflammatory bowel disease and cholangitis as ‘triaditis.’ Because it kills appetite, a cat that stops eating can develop fatty liver, and in severe cases that is life-threatening — so a confirmed case needs prompt clinic care.
2 How It Develops
Pancreatitis comes from the pancreas digesting itself via trypsin. The usual routes:
A drop in immunity lets an infection elsewhere in the body go untreated and spread to the pancreas.
Long-term or sudden heavy feeding of high-protein, high-fat food overloads the pancreas.
A blockage of the pancreatic duct raises pressure until acini rupture and enzymes leak out.
3 Symptoms and Diagnosis
The main signs are frequent vomiting, poor digestion, lost appetite, lethargy, a yellow tint to the skin, and a tender, painful belly. Clinical signs alone rarely confirm it.
Diagnosis combines the cat’s history, bloodwork, and a basic physical exam for a first read.
When a cat vomits repeatedly from pancreatitis, withhold food and water, then get it to a clinic at once for fluids and the right treatment.
