How can you figure out the gender of a mouse?

Answer 1

If you don't know already your mouse is probably female, large testicles and male-like behavior are another hint. The testicles are pretty obvious in mice and rats. A male mouse's penis would be more where our belly buttons are. Also, in adult mice, testicles are usually easily visible.

Answer 2

There is a lot of difference in the male and female rat. The male rat usually has very large teticles. On rare occasions, they may not desend and show - then you would need to look at the area to judge distance of the vaginal opening and the anus. The distance on a female is closer than that of a male.

Answer 3

Male mice have testes and their "area" is farther from their anus.

Female mice have their "area" closer to their anus.

Answer 4

look at it's bum. If it has a tear shaped hole then it's a girl if it has two testicals it's a boy. Shouldn't the pet shop you got it from have told you?!

Answer 5

Well, a male has a thing sticking out and the female doesn't.

Answer 6

Male rats have very obvious testicles after they mature a little bit. This is common among rodents. Basically, you just have to turn them over and take a look.

Answer 7

look underneath it

Answer 8
