Short answer: Pancreatitis is not rare in cats. While only a small percentage show obvious clinical illness, up to 66% of cats may have pancreatitis on microscopic examination, often mild or chronic and without clear symptoms. pmc.ncbi.nlm.nih.gov
🐾 What the data shows
Veterinary research gives us two different perspectives:
1. Clinical (diagnosed) pancreatitis
- Diagnosed far less often than it actually occurs.
- Most vets see it mainly in cats with vomiting, lethargy, abdominal pain, or loss of appetite.
- No strong age, sex, or breed predisposition. pmc.ncbi.nlm.nih.gov
2. True prevalence (found at necropsy)
A major study of 115 cats found:
- 66.1% had pancreatitis on histopathology.
- 50.4% chronic pancreatitis
- 6.1% acute pancreatitis
- 9.6% both acute + chronic
- Even 45% of apparently healthy cats had pancreatitis. pmc.ncbi.nlm.nih.gov
This suggests many cats have subclinical or mild chronic pancreatitis that never becomes obvious.
Why is it so common but rarely diagnosed?
- Cats often show very vague symptoms (lethargy, decreased appetite).
- Chronic pancreatitis tends to be mild and slow‑moving.
- Diagnostic tests (ultrasound, fPLI) are helpful but not perfect.
- Many cases are only discovered incidentally.
Should cat owners worry?
Not necessarily — but it is worth being aware of.
When to be alert:
- Repeated vomiting
- Sudden loss of appetite
- Lethargy
- Pain or hunched posture
- Weight loss
- Cats with diabetes, IBD, or liver disease (these often occur together)
If you’re noticing symptoms, a vet can run blood tests and imaging to check for pancreatitis.
