Tissue specimens from twenty clinically healthy client-owned cats were collected from the stomach and duodenum and evaluated single blinded by a board-certified pathologist. In addition, samples were evaluated by routine immunohistochemistry and clonality testing. Samples were found to have abnormal findings on histopathology, immunohistochemistry, clonality testing, or some combination of these without apparent clinical relevance. This study suggests that current diagnostic metrics for diagnosing chronic enteropathy in cats may need modification to be applicable to the general population of cats.
