Pancreatitis in cats is a common gastrointestinal condition with a variety of symptoms, which makes it easy to overlook. It’s essential to understand the symptoms, diagnosis, treatment, and prevention because if left untreated can progress quickly in cats and can be life-threatening.

What is Pancreatitis in Cats?

The pancreas is an organ that forms part of the endocrine and digestive system. It produces hormones such as insulin, which supports blood sugar levels (endocrine function). It also secretes a controlled amount of digestive enzymes into the intestinal tract, which activates in the small intestine aiding with digestion (exocrine function).

Pancreas anatomy explained

Pancreatitis occurs when the pancreas becomes inflamed. The exocrine function will become affected. The digestive enzymes will start activating early and cause the digestion in the pancreas and other parts of the body, such as the liver and kidney.

Pancreatitis in cats is often found concurrently with other diseases, such as inflammatory bowel disease (inflammation of the intestines) and cholangitis (inflammation of the liver), this is due to the proximity to each other. The simultaneous inflammation of these three organs refers to “Feline Triaditis”.cat at the veterinary clinic I Love Veterinary

What is the cause of Pancreatitis in Cats?

In most cases, pancreatitis isn’t linked to a specific cause. There are different causes, some of them are:

  • Abdominal trauma: This could involve the recovery from a road traffic accident. 
  • Genetics: Siamese cats are more prone to the condition. 
  • Adverse medication reactions: An example of a drug-associated with pancreatitis in cats is Azathioprine.
  • Infections: May cause pancreatitis in particular feline leukemia virus and feline herpes virus.  
  • Diseases: Such as inflammatory bowel disease and diabetes mellitus.
  • Toxic substances: For example, organophosphates.

Clinical Symptoms of pancreatitis in cats

There are no clinical signs that are specifically related to pancreatitis in cats; therefore, it’s essential to observe the pet and look out for any of the following symptoms:

  • Absent appetite
  • Weight loss
  • Lethargy
  • Dehydration
  • Diarrhea, vomiting, and fever: less common signs of pancreatitis in cats

How is it Diagnosed?

When a case of pancreatitis is suspected, there are a few methods that a veterinarian can use to diagnose pancreatitis.

  • Snap tests for pancreatitis in cats: Feline pancreatic lipase immunoreactivity (fPLI) is known as the most accurate test to determine pancreatitis. It measures a lipase (enzyme) in the blood, and the values increase when there is an inflammation in the pancreas.
  • Abdominal ultrasound: Is another way of diagnosing feline pancreatitis. An ultrasound can show irregular pancreatic margins, hyperechoic fat, and abnormal size and shape of the pancreas.
  • Radiographs and complete blood count: can help with a further study of other concurrent issues, for example, diabetes mellitus.
  • Surgery: Such as exploratory laparotomy to observe any abnormalities.
  • Pancreatic biopsy: This method helps to prove a definitive diagnosis of pancreatitis.
