Chronic Vomiting in Cats: Welfare and Diagnosis

Understanding why cats vomit chronically and how accurate diagnosis improves welfare.

Key Facts

Chronic vomiting in cats is often under-investigated as normal
Inflammatory bowel disease, food intolerance, and small cell lymphoma are common causes
Endoscopy and biopsy distinguish IBD from lymphoma — critical for treatment planning
Hypoallergenic diet trials are a low-risk first investigation in mild cases

Welfare Considerations

Chronic vomiting causes ongoing discomfort and nutritional compromise. Welfare-focused care investigates rather than normalising the signs — many cats benefit significantly from specific treatment once a cause is identified. Small cell lymphoma responds well to chlorambucil and prednisolone — welfare outcomes are excellent with treatment.

What You Can Do

Do not accept chronic vomiting as normal in cats — investigate the cause
Request an ultrasound and dietary trial before accepting a diagnosis of idiopathic vomiting
Ask about endoscopy and biopsy if medical management is not improving your cat
