Ileal polyps in Siamese cats

Intestinal obstruction occurred in a 2-year-old Siamese cat with a mucosal polyp in the lower ileum. A daughter of this cat also developed an intestinal obstruction at 21/2 years of age; a similar lesion was found on her ileum. The cause of these polyps is not known, but the familial occurrence in young animals suggests an hereditary influence.
