Congenital megacolon is not well studied in cats and dogs but does appear to occure in both species. Any age, breed or sex of animal may develop aquired megacolon, but idiopathic megacolon is more common in middle-aged to older cats. There is also some evidence for an increased risk of megacolon in Manx cats.

Megacolon much more commonly affects cats than dogs, but any age, breed or sex of animal may develop aquired megacolon. Idiopathic megacolon is more common in middle-aged to older cats, and there is some evidence for an increased risk in Manx cats due to a sacral spinal cord deformity.
