When Can You Tell The Sex Of A Kitten?

The sex of a kitten happens when the kitten is 2-3 weeks old. It’s very difficult to determine whether a kitten is male or female based on its appearance at birth. Kittens are born with dark skin and hair, so they can’t be distinguished from each other in this way until their fur has started growing back. Some people will try to guess early on if their kittens are male or female by looking for external genitalia, but this isn’t always possible because genitals can look different depending on how the cat was carried during pregnancy and where it came out of the womb — there may not be any visible evidence that it’s a boy or girl inside!
