Pancreatitis, the most common disorder affecting the pancreas in cats, is an inflammatory condition that can vary from mild to severe, with some cases proving life-threatening. Despite being common, feline pancreatitis is challenging to diagnose, and many cases go undetected. With advancements in diagnostic tools and increased awareness, more cases are now being identified, offering better outcomes for cats when treated early.
Here’s what you need to know as a cat owner to understand and manage feline pancreatitis.
What Is Pancreatitis?
Pancreatitis refers to inflammation of the pancreas, an organ responsible for producing enzymes that aid digestion and hormones like insulin to regulate blood sugar.
In cats, pancreatitis occurs in two main forms:
1. Acute Pancreatitis: Sudden inflammation, often more severe, characterised by the breakdown of pancreatic tissue and fat and inflammation caused by immune cells.
2. Chronic Pancreatitis: Long-term inflammation that can lead to fibrosis (scarring) of the pancreas. This form tends to be milder but can persist over time, with flare-ups of symptoms.
In some cats, both acute and chronic forms can occur simultaneously, leading to what’s known as “chronic active pancreatitis.”
What Causes Pancreatitis in Cats?
The cause of pancreatitis in cats often remains unknown, making it a tricky condition to prevent. However, it is frequently associated with other conditions, especially inflammatory bowel disease (IBD) and cholangitis (inflammation of the bile ducts). When pancreatitis occurs alongside these conditions, it is referred to as triaditis, a common combination in cats. Studies suggest that 50%–67% of cats with pancreatitis also have triaditis, indicating a close relationship between these disorders.
While less common, other factors that may contribute to pancreatitis in cats include:
- Trauma: Physical injury to the abdomen.
- Infections: Certain viruses or parasites.
- Toxins: Rare cases have been linked to toxins or medications.
- Diabetes Mellitus (DM): Pancreatitis may develop alongside diabetes, though the exact link remains unclear.
Symptoms of Pancreatitis
Pancreatitis in cats is often tricky to identify because the symptoms are subtle and can mimic other conditions. Common signs include:
- Loss of Appetite (Hyporexia/Anorexia)
- Lethargy or lack of energy
- Vomiting: Less common in cats than dogs, but can still occur quite frequently
- Dehydration and Jaundice: Icterus (yellowing of the skin and eyes) may occur in more severe cases
- Weight Loss and Diarrhoea: Occasional signs, especially in chronic cases
Unlike dogs, cats with pancreatitis may not show obvious signs of abdominal pain, making it more difficult to diagnose based on symptoms alone.
Diagnosing Pancreatitis
Diagnosing feline pancreatitis can be challenging.
While routine blood tests and ultrasounds can help rule out other conditions, they are often not specific enough to confirm pancreatitis. The most reliable diagnostic tests include:
- Serum Pancreatic Lipase Immunoreactivity (fPLI): This blood test detects pancreatic-specific enzymes, making it the most accurate non-invasive test available for pancreatitis.
- Abdominal Ultrasound: Can detect inflammation in the pancreas may miss mild or chronic cases.
- Biopsy: The gold standard for diagnosis but is invasive and risky, especially for sick cats.
Often, a combination of clinical signs, blood tests, and imaging is used to make a diagnosis.
How Is Pancreatitis Treated?
There is no specific cure for pancreatitis, so treatment is focused on supportive care to manage symptoms and help the pancreas recover.
Treatment typically involves:
1. Fluid Therapy: Cats with pancreatitis are often dehydrated and may require intravenous or subcutaneous fluids to maintain hydration and electrolyte balance.
2. Pain Relief: Pancreatitis can be painful, and cats may need analgesics to manage discomfort.
3. Anti-Nausea Medication: To control vomiting and promote a return to eating.
4. Nutritional Support: Cats are prone to developing liver problems if they stop eating for too long, so it’s crucial to reintroduce food as soon as possible, even if it means using feeding tubes.
5. Antibiotics and Corticosteroids: These may be used in cases with infection or when the inflammation is linked to autoimmune diseases.
Managing Chronic Pancreatitis
Chronic pancreatitis can often be managed at home with regular monitoring and a focus on maintaining a healthy diet. Cats with chronic conditions may require periodic pain management and fluid therapy to prevent dehydration. In some cases, corticosteroids may be used to control inflammation.
Complications of Feline Pancreatitis
While many cats with pancreatitis recover well, complications can arise, especially in severe cases. These include:
- Diabetes Mellitus: Damage to the pancreas can lead to diabetes in some cats, requiring lifelong insulin therapy.
- Hepatic Lipidosis (Fatty Liver Disease): Prolonged anorexia can lead to liver issues, particularly in overweight cats.
- Bile Duct Obstruction: Inflammation from pancreatitis can cause bile ducts to become blocked, leading to jaundice and requiring surgical intervention in some cases.
Prognosis
The outlook for cats with pancreatitis varies. Cats with mild cases often recover well with supportive care, while severe cases, particularly those complicated by other conditions like hepatic lipidosis or diabetes, carry a more guarded prognosis. Early detection and prompt treatment are critical to improving outcomes.
Conclusion
Pancreatitis in cats is a common but often underdiagnosed condition. If your cat shows signs of lethargy, loss of appetite, or vomiting, it’s important to seek veterinary care. With proper diagnosis and supportive treatment, many cats can recover from both acute and chronic forms of pancreatitis.
