Feline inflammatory bowel disease causes chronic gastrointestinal suffering and is often confused with or coexisting with small cell lymphoma, requiring careful diagnosis and management.
Feline IBD causes chronic gastrointestinal discomfort that is difficult to quantify but welfare-significant over years of disease. Cats with active IBD vomit frequently, experience nausea that reduces food intake, and lose weight progressively. The chronic nature of the disease means welfare impact accumulates — a cat vomiting several times weekly over years experiences substantial cumulative suffering. Diagnosis is complicated by the need for biopsy, which requires anesthesia, and by the significant overlap between IBD and small cell lymphoma that requires pathology expertise to distinguish. Treatment responses are generally good — dietary management and corticosteroids achieve meaningful symptom control in most cases. The welfare priority is accurate diagnosis followed by consistent treatment and monitoring, recognizing that management rather than cure is the realistic goal for most affected cats.
