Pancreatitis in cats: life expectancy and recovery time

Most cats with pancreatitis survive it, and a cat with mild or chronic pancreatitis often lives for years with occasional flare-ups. The exception is severe acute pancreatitis, which can be fatal within days even with hospital care. There is no single survival figure, because the outlook depends on how severe the episode is and on what other illnesses the cat has.

An acute episode itself commonly lasts from a few days to a couple of weeks with treatment. Your own vet, who has the blood results and the scan, gives the real prognosis for your cat.

How long does pancreatitis last in cats?

That depends on which kind your cat has. The pancreas makes digestive enzymes and insulin, and pancreatitis is inflammation of it. It can come on suddenly (acute) or smolder at a low level for months or years (chronic). In cats the chronic form is thought to be the more common one.

These are commonly reported time frames and they vary from cat to cat. Appetite is the best guide at home. Many cats with a mild episode start eating again within a few days of starting treatment. If yours is still refusing food a day or two into treatment, tell the vet; it needs a recheck, not more time.

For the signs, tests and treatment in detail, see our guide to pancreatitis in senior cats.

Life expectancy with chronic pancreatitis

Chronic pancreatitis is often something a cat lives with, not something it dies of. Many cats have long periods of eating and behaving normally, broken by flare-ups in which they go quiet, eat less and sometimes vomit. With flares treated early, many of these cats live for years.

What shortens that is damage adding up over time. Repeated inflammation can scar the pancreas, and a cat that loses weight with every flare has less in reserve for the next one.

What changes the outlook

How severe the episode is

Severe acute pancreatitis affects the whole body. Features that vets associate with a poorer outlook include shock, low blood sugar, low blood calcium, worsening kidney values, trouble breathing and signs that other organs are struggling. These cats need intensive care, and some do not survive in spite of it.

Whether the cat keeps eating

A cat that stops eating for more than a few days can develop fatty liver disease (hepatic lipidosis), which is serious in its own right and makes recovery slower and less certain. Overweight cats are at particular risk. This is why vets push feeding early, with anti-nausea medicine, appetite stimulants and sometimes a feeding tube. A feeding tube is a treatment, not a last resort. See why an old cat stops eating for the other causes a vet will consider.

Prognosis for a senior cat with pancreatitis and diabetes

The two are often found together, and each makes the other harder to manage. Inflammation in the pancreas can damage the cells that make insulin, and a flare-up can change how much insulin a diabetic cat needs from one week to the next. A flare can also tip a diabetic cat into diabetic ketoacidosis, which is an emergency.

Many cats with both conditions are still managed for years. They need closer monitoring than a cat with either one alone, and the outlook is more guarded if flares are frequent or the diabetes is hard to control. Insulin doses are set and changed only by your vet. More in diabetes in senior cats.

Liver or bowel disease at the same time (triaditis)

Some cats have pancreatitis together with inflammation of the liver and bile ducts and inflammatory bowel disease. Vets call the combination triaditis. Recovery tends to be slower, relapses are more likely, and all three conditions need treating. Yellowing of the gums, ears or the whites of the eyes can point to liver involvement and needs a vet the same day.

Age and other illnesses

Older cats have less in reserve. Kidney or heart disease affects how fluids can be given and which medicines a vet can use. Muscle already lost to age or to an overactive thyroid is hard to rebuild after a week of not eating. None of this means an old cat cannot recover, and many do, but recovery is usually slower than in a young cat. Our senior cat guide covers the routine checks that catch these problems early.

Are there stages of pancreatitis in cats?

No. Unlike kidney disease, pancreatitis has no formal staging system. Vets describe it as acute or chronic, and as mild, moderate or severe. Blood tests and ultrasound help, but they do not always match how sick the cat is.

When chronic pancreatitis does progress, it tends to show as:

• Flare-ups that come closer together or take longer to settle.
• Gradual weight and muscle loss. See why an old cat loses weight.
• Diabetes developing: more thirst, more urine, weight loss with a good appetite.
• Less often, the pancreas no longer making enough digestive enzymes, which causes weight loss with a big appetite and bulky, greasy stools. Vets treat this with a prescribed enzyme supplement.

What helps a cat live longer with pancreatitis

• Act early on appetite. Call the vet on the first day your cat goes off food, before weight is lost.
• Give prescribed medicines as directed. Anti-nausea medicine, pain relief and appetite stimulants are chosen and dosed by your vet for your cat.
• Follow the vet's advice on food. During a flare, getting a cat to eat usually matters most. Whether a special diet is needed long term depends on what else your cat has, such as diabetes, kidney disease or bowel disease. Do not change foods suddenly.
• Weigh your cat regularly on the same scale, and keep a note of it.
• Keep the rechecks. Repeat blood tests pick up diabetes and liver changes before they cause a crisis.

Pancreatitis is painful, and cats hide pain well; our guide to the signs of pain in senior pets describes what it looks like. Never give a cat a human painkiller. Ibuprofen, naproxen, acetaminophen and aspirin can seriously harm or kill cats. Other human stomach or anti-nausea products should only be given if your vet has confirmed the exact product and amount.

Call the vet today if

Call your vet or an emergency clinic now if your cat:

• Has not eaten for a full day, or is eating far less than normal for two days.
• Is vomiting repeatedly, or cannot keep water down.
• Is hiding, hunched, or cries when picked up or touched around the belly.
• Has yellow gums, ears or eyes.
• Is weak, wobbly, cold to the touch, or has collapsed.
• Is breathing fast or with effort.
• Is diabetic and stops eating, vomits or becomes dull. Call before giving the next insulin injection and ask what to do.
• Was recovering and has gone downhill again.

Pancreatitis can worsen quickly, so decisions about testing, treatment, diet and insulin should be made with your veterinarian.
