How do you tell the gender of a kitten?

Look carefully at the space between the genital opening and the anus. If you see a small bulge or pouch, it's likely the scrotum, and thus the kitten is male.If you can't visually detect a scrotum, you can feel for them in kittens that are at least a month or two old.

If your cat is female, you'll find her genital opening (vulva) immediately below her anus, and it will be in the shape of a vertical slit. If your cat is male, his genital opening (penis) will be a noticeable distance from his anus – about ½ inch in kittens and 1 inch in adults – and will be a rounded shape.
