What Is Feline Pancreatitis?
Pancreatitis — inflammation of the pancreas — is one of the most underdiagnosed conditions in cats. Unlike dogs, who often present with dramatic vomiting and abdominal pain, cats with pancreatitis tend to display subtle, non-specific signs that are easy to dismiss. The pancreas plays a vital role in producing digestive enzymes and regulating blood sugar, so when it becomes inflamed, the consequences can be wide-ranging and serious.
The condition can occur in two forms: acute (sudden onset) and chronic (long-term, low-grade inflammation). Chronic pancreatitis is far more common in cats and can smoulder quietly for months before it is detected. According to ECVIM-CA (the European College of Veterinary Internal Medicine — Companion Animals), feline pancreatitis is often concurrent with other gastrointestinal diseases, making diagnosis particularly challenging.
Recognising the Symptoms
Because cats are masters at masking illness, the symptoms of pancreatitis are frequently vague and easy to attribute to other causes. The most commonly reported signs include:
- Lethargy and reduced activity
- Anorexia or markedly decreased appetite
- Weight loss over weeks or months
- Occasional vomiting (less frequent than in dogs)
- Dehydration
- Hunched posture or signs of abdominal discomfort
- Jaundice (yellowing of the skin or eyes) in severe cases
It is important to note that not all cats will display every symptom. A cat that simply seems "off" or has been eating less for several days warrants veterinary attention, particularly if it is middle-aged or older.
Diagnosing Pancreatitis: The fPLI Test
Diagnosing feline pancreatitis has historically been difficult because routine blood tests and even ultrasound examinations can appear normal in affected cats. The most reliable and widely recommended diagnostic tool is the feline pancreatic lipase immunoreactivity test, commonly known as the fPLI or Spec fPL test.
This blood test measures the concentration of pancreatic lipase specifically produced by the feline pancreas. It is significantly more sensitive and specific than traditional lipase assays. ECVIM-CA guidelines recommend the Spec fPL test as the single best non-invasive diagnostic test for feline pancreatitis. Abdominal ultrasound can be used as a complementary tool, and in some cases, a pancreatic biopsy may be necessary to confirm chronic pancreatitis definitively.
Understanding Triaditis
One of the most important concepts in feline internal medicine is triaditis — the concurrent occurrence of pancreatitis, inflammatory bowel disease (IBD), and cholangitis (inflammation of the bile ducts and liver). This trio of conditions is frequently seen together in cats, and ECVIM-CA specialists have highlighted its significance in clinical practice.
The three organs — the pancreas, small intestine, and liver/biliary system — share a common drainage point in cats, which is thought to facilitate the spread of inflammation between them. A cat diagnosed with one of these conditions should always be investigated for the other two. Managing triaditis requires a coordinated treatment approach that addresses all three components simultaneously.
Treatment Options
There is no single cure for feline pancreatitis; treatment is largely supportive and aimed at managing symptoms while the pancreas heals. Fluid therapy is a cornerstone of treatment, particularly in acute or severe cases, to correct dehydration and maintain organ perfusion.
Nausea and vomiting are managed with antiemetic medications. Maropitant (marketed as Cerenia) is the most commonly used antiemetic in veterinary practice and is highly effective in cats. It works by blocking the neurokinin-1 receptors involved in the vomiting reflex and also has some anti-inflammatory properties in the gastrointestinal tract. Your vet may administer this by injection in hospital or prescribe tablets for home use.
Pain management is equally important, as pancreatitis can be painful even when cats do not show obvious signs of distress. Buprenorphine is frequently used for analgesia in feline patients.
Nutritional Support and Feeding Tubes
The old advice of "resting the pancreas" by withholding food is now considered outdated and potentially harmful. Current ECVIM-CA recommendations support early nutritional intervention, as prolonged anorexia in cats can rapidly lead to hepatic lipidosis (fatty liver disease).
For cats that are willing to eat, a highly digestible, low-fat diet is recommended during recovery. Prescription gastrointestinal diets such as Hills i/d and Royal Canin Gastrointestinal are excellent options and are available through Zooplus, making reordering straightforward once your cat is eating well at home. These diets are formulated to minimise pancreatic stimulation whilst providing the nutrients needed for recovery.
In severe cases where cats refuse to eat voluntarily, feeding tubes may be necessary. Naso-oesophageal tubes can be placed without anaesthesia for short-term use, while oesophagostomy tubes are preferred for longer-term nutritional support and are generally well tolerated by cats at home.
Vitamin B12 Supplementation
Cobalamin (Vitamin B12) deficiency is extremely common in cats with chronic pancreatitis and associated gastrointestinal disease, as the small intestine's ability to absorb this vitamin is impaired. Low cobalamin levels are associated with poor appetite, lethargy, and a worse clinical outcome. Supplementation — typically given as weekly subcutaneous injections or oral cyanocobalamin drops — is a simple but highly effective part of managing these cases. Your vet should check cobalamin levels as part of the diagnostic workup.
Long-Term Management and Prognosis
Cats with acute pancreatitis can recover fully with prompt and appropriate treatment, though some will go on to develop chronic disease. Chronic feline pancreatitis requires ongoing management, including regular veterinary monitoring, long-term dietary support, and treatment of any concurrent conditions such as IBD or cholangitis.
Owners play a crucial role in monitoring their cat's appetite, body weight, and general demeanour at home. Any significant decline should prompt a veterinary check-up and possible repeat fPLI testing. With careful, consistent management, many cats with chronic pancreatitis can enjoy a good quality of life for years.
