Abstract
Gastric trichobezoars (hair balls) are frequently found in rabbits but are rarely reported in rats. Several Wistar-Kyoto rats fed a semi-pur ified diet developed anorexia and abdominal tenderness. Proteolysis th erapy with fresh papaya and commercially prepared enzyme was attempted in these rats but was not successful. The prevalence of trichobezoars at necropsy was 100%. We conclude that semi-purified diets contribute to trichobezoar formation in rats, but proteolysis therapy is not eff ective in dissolving the trichobezoars.
