Cat Inflammatory Bowel Disease | Animal Welfare Hub

Feline inflammatory bowel disease (IBD) is a chronic condition causing gut inflammation that significantly impacts quality of life if poorly managed.

Key Facts

IBD is one of the most common causes of chronic vomiting, diarrhoea, and weight loss in cats.
Lymphocytic-plasmacytic enteritis is the most common form, though other cell types can predominate.
Diagnosis requires intestinal biopsy; ultrasound and bloodwork help stage severity.
IBD and small cell gastrointestinal lymphoma can be difficult to distinguish without histopathology.
Dietary management with novel protein or hydrolysed diets helps many cats alongside immunosuppressive therapy.

Welfare Considerations

Cats with IBD experience chronic discomfort including nausea, cramping, and the distress of frequent vomiting or diarrhoea. Uncontrolled IBD leads to progressive weight loss, muscle wasting, and vitamin B12 deficiency. Treatment with prednisolone and/or chlorambucil can induce remission in many cats, dramatically improving quality of life. Long-term management requires regular monitoring for treatment side effects and disease progression. Owners play a vital role in tracking symptoms and ensuring consistent medication administration.

What You Can Do

Seek specialist gastroenterology referral if your cat has chronic digestive symptoms.
Learn to give injectable vitamin B12 (cobalamin) at home if your vet prescribes it.
Keep a symptom diary to track vomiting, appetite, and weight to guide treatment adjustments.
Discuss quality-of-life assessment with your vet, especially if your cat has concurrent lymphoma.
