Determining Gender (Sex) of a Kitten

Apr 7, 2020


Determining the sex of a kitten is easy when you know what to look for.

Start by lifting the kitten's tail. The opening just under the tail is the anus. Below the anus is the genital opening which is round in males and is a vertical slit in females. In kittens of similar size, the distance between the anus and the genital opening is greater in the male than the female.

The color of the kitten may suggest its gender. Almost all kittens of calico (black, white and orange) or tortoiseshell (black and orange) color are females. More orange kittens are male than female.
