Five cats had gastrointestinal histology performed: 3 CD4+ T‐cell cats were diagnosed with intestinal lymphoma, 1 heterogeneous case had lymphoplasmacytic and eosinophilic enteritis, and 1 CD8+ T‐cell case had lymphocytic gastritis with associated helicobacter organisms. Here, CD4 is linked to eosinophilic gastroenteritis.
