What do newborn kittens think of male and female pictures?

1. Newborn kittens can tell the sex through their anus and genitals.

2. The owner gently pulls the cat's tail, and then looks at the distance between the cat's anus and reproductive tract. If the distance between the cat's anus and the genital hole is very short, about one finger away, it means that the cat is a female cat.

3. If the distance between the genital hole and the anus of the cat is far away, there are about two fingers, which means that the cat is a male cat.
