Pancreatitis in Cats: Vague Signs, Diagnosis and Treatment

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

The pancreas sits near the stomach and small intestine and does two jobs: it makes enzymes for digestion and hormones such as insulin. When it becomes inflamed, the condition is called pancreatitis. In cats, the signs are often vague, and the disease can be hard to diagnose, so it helps to know what to watch for.

Acute and chronic forms

Acute pancreatitis comes on suddenly and can be severe. Chronic pancreatitis is a long-term, lower-grade inflammation, and many cats have mild forms that are never diagnosed. In some cats the disease flares up repeatedly.

What causes it?

In most cats, no single cause is found. Possible contributing factors include:

• Inflammatory bowel disease and other gut inflammation, sometimes described as triaditis when the liver and intestines are also involved
• Liver and bile duct disease
• Diabetes. See diabetes in cats.
• Abdominal trauma or surgery
• Infections or parasites, such as liver flukes in some regions
• Certain drugs and toxins
• Obesity and high-fat diets, less clearly in cats than in dogs

Signs

Cats rarely show the dramatic signs seen in dogs. Common signs are:

• Lethargy and weakness
• Reduced appetite or refusing food
• Hiding or sleeping more
• Dehydration
• Weight loss
• Vomiting, less common
• Diarrhea, sometimes
• Abdominal pain, with a hunched posture
• Low body temperature or fever in severe cases
• Yellow gums or skin if the liver is affected

Because signs overlap with many other illnesses, see cat vomiting causes and diarrhea in cats.

Why not eating is dangerous

A cat that stops eating for even a couple of days can develop a serious liver condition called hepatic lipidosis. Pancreatitis and poor appetite together make this risk higher. See hepatic lipidosis in cats. Call a vet if your cat has not eaten for 24 hours, and see the emergency warning signs guide.

Diagnosis

Diagnosis combines several tests:

• Physical exam
• Blood tests, including liver, kidney and glucose levels
• A feline pancreatic lipase test, such as a specific pancreatic lipase immunoreactivity (fPLI) test
• Abdominal ultrasound, which can show changes and rule out other problems
• X-rays to look for blockages or other causes

No single test is perfect, so vets weigh the whole picture.

Treatment

Treatment is supportive, since there is no cure for the inflammation itself.

• Fluids to correct dehydration and support the pancreas
• Pain relief, often opioids
• Anti-nausea drugs and appetite stimulants
• Early nutrition. Current practice favors feeding as soon as the cat can tolerate it, by mouth or by a feeding tube, rather than prolonged fasting
• Treatment of other diseases, such as diabetes or inflammatory bowel disease
• Hospital care in severe cases

Home care after discharge may include special diets, medication and recheck tests. Follow your vet's plan, and see how to give a cat a pill.

Outlook

Mild cases often recover within days to weeks. Severe cases carry a more guarded outlook. Chronic pancreatitis may recur and needs ongoing management. Cats with diabetes may become harder to regulate.

Prevention

• Keep your cat at a healthy weight. See how to help an overweight cat lose weight.
• Feed a balanced diet, and avoid sudden changes. See how to switch cat foods.
• Keep toxins and medications away. See cat poisoning what to do.
• Schedule regular checkups. See senior cat care guide.

Pancreatitis and diet

Evidence on diet in feline pancreatitis is limited. Your vet may suggest a highly digestible, moderate-fat diet for recovery, or a prescription gastrointestinal food, especially if inflammatory bowel disease is present. Do not make abrupt changes. See how to switch cat foods.

Pancreatitis and diabetes

The pancreas makes insulin, so repeated inflammation can damage insulin-producing cells and contribute to diabetes. A cat with diabetes that becomes unwell, or whose blood sugar becomes hard to control, may have pancreatitis. See diabetes in cats.

Monitoring at home

Weigh your cat weekly, track appetite and note vomiting, stool changes and energy. Report a decline right away. Keep follow-up appointments, since blood tests help judge recovery.

Cost of care

Hospital treatment, blood tests and ultrasound can add up, so discuss options and estimates with your vet early. See cat pet insurance guide for ways to plan ahead. Ask which tests are essential and which can wait if money is tight.

When to see a vet

If your cat is lethargic, hiding or eating less, do not wait. Use the US vet directory to find a clinic, and see cat vet visit costs.
