our pet rat

Question
hi we have a pet rat and we can't tell if she is a boy or a girl anyways i put the rat in a cage wit a boy rat for like a week or two. and i notices her stomach look kinda of big just her stomach, thats no all she would bit if some one picked her up she never did that before she's bitting kids and us to so what does that mean

Answer
A male rat has Very large testicles at the base of the tail, Even at a young age you can tell so chances are you have a female rat that is pregnant. Many rats become testy during pregnancy.

Separate the two ASAP as the male can cause stress to the female and even eat the young. Also leave your rat alone and give a nice dark room so she feels safe.

Good Luck!
