Feline Inflammatory Bowel Disease: Welfare and Long-Term Management

Inflammatory bowel disease (IBD) is a common cause of chronic vomiting and diarrhoea in cats, causing persistent gastrointestinal discomfort and requiring long-term dietary and medical management.

Key Facts

Feline IBD encompasses a spectrum of chronic idiopathic intestinal inflammatory conditions
Clinical signs include chronic vomiting, diarrhoea, weight loss, and reduced appetite
Diagnosis requires intestinal biopsy to characterise the inflammatory infiltrate type
Dietary modification alone resolves clinical signs in approximately 50% of cats
Immunosuppressive therapy with prednisolone or chlorambucil is required for refractory cases

Welfare Considerations

Feline IBD causes persistent gastrointestinal discomfort through chronic mucosal inflammation, causing nausea, pain, and reduced food motivation. Cats with poorly controlled IBD experience ongoing nausea, urgency, and the discomfort of chronic diarrhoea or vomiting. Weight loss and muscle wasting further reduce quality of life. Early diagnosis through endoscopy and biopsy enables targeted treatment, with dietary hydrolysate or novel protein diets offering a non-pharmacological first-line approach. Regular monitoring of clinical response and body weight guides treatment adjustments in this chronic condition.

What You Can Do

Seek veterinary assessment for any cat with chronic vomiting, diarrhoea, or weight loss
Request intestinal biopsy for definitive IBD diagnosis where appropriate and feasible
Trial a strict 8-week dietary elimination or hydrolysate diet before commencing immunosuppression
Monitor body weight and clinical signs regularly to assess treatment effectiveness
Discuss long-term monitoring protocols including cobalamin levels and intestinal ultrasound with your vet
