Distinguishing feline inflammatory bowel disease from intestinal lymphoma requires biopsy but has major welfare implications — different conditions require different treatments with very different prognoses.
The welfare implication of correctly distinguishing feline IBD from intestinal lymphoma is substantial: misdiagnosis means wrong treatment, prolonged suffering, and potentially a much shorter comfortable life. Small cell lymphoma — the most common intestinal cancer in cats — is highly treatable, and cats accurately diagnosed and appropriately treated can enjoy years of good quality of life. The barrier is that definitive diagnosis requires biopsy, which owners sometimes decline due to cost or risk concern. Empowering owners with accurate information about prognosis and treatment success rates for SCL often changes this calculus — the welfare benefit of correct diagnosis and treatment outweighs the diagnostic procedure risk substantially.
