Successful surgical separation of asymmetrical caudal duplication or parasitic twinning in a kitten.

A good outcome is rare in parasitic twinning because many of these animals present with other concurrent health issues, such as congenital heart malformation or cleft palate, or they are stillborn. However, this pathological entity is scarce in small animal medicine, and there is no documented survival rate. To our knowledge, this is the first officially documented case of parasitic twinning-omphalopagus in a cat in the past decade.
