Difference in Male and Female Kittens

Male and female newborn kittens can be difficult to tell apart. Knowing the difference between the two is important for breeders, especially if new potential owners are looking to adopt a female kitten over a male or vice versa.

  1. Warning

    • At birth, all kittens should be checked for two openings beneath the tail: one anus and one marking the genitals. Kittens with only one opening should be seen by a veterinarian immediately, as this is a life-threatening situation.

    Age

    • Once the kittens have reached a certain age, usually around four to six weeks, it can be easier to determine the difference between the two.

    Male Kittens

    • At birth, the two openings below the tail are farther apart from each other in comparison to a female kitten. By six weeks, the testicles of a male kitten can be felt.

    Female Kittens

    • In female kittens, the two openings are closer together. The female kitten also features a vertical slit representing the vagina in contrast to the circular opening for the penis of a male kitten.

    Color

    • In some cases, kittens can be told apart by colors. Tortoiseshell and calico-colored kittens are both highly likely to be female. Meanwhile, orange kittens tend to be male. However, kittens should still be checked, as it is possible for these colors to occur on the opposite sex.
