No clearance was observed in 29% of dogs fed liquid, in 43% of dogs fed slurry and 67% of dogs fed meatballs. There was a significant difference (p < 0.001) between groups with the ECT of liquid being faster compared to both meatballs and slurry. There was no significant difference in ECT between slurry and meatballs, but the median percentage of esophageal clearance was 50% (interquartile range 0-79%) for slurry and 0% (interquartile range 0-60%) for meatballs. (7), hemorrhage (2), mucosal irregularity (5), and a polypoid lesion (1) . Intestinal lesions included erosions (3), hemorrhage (1), irregular mucosa (5), and a mass in the duodenum (1) and jejunum (1) . (1) Cats with chronic enteropathy frequently undergo endoscopy and assessment of intestinal biopsies using histopathology, immunohistochemistry, and clonality testing (PCR for antigen receptor rearrangements (PARR)). However, there is a paucity of data on findings for these modalities in a cohort of healthy cats. Thus, the aim of this study was to describe results of histopathology, immunohistochemistry, and PARR in endoscopically derived duodenal biopsy specimens from clinically healthy, client-owned cats.
