The difference between male and female mice is judged by genitals. The genitals and anus of female rats are relatively close, while the genitals and anus of male rats are relatively far away. In addition, mature male rats will have prominent testicles, such as golden mice, gerbils and macaroni mice. It will be obvious, but the maple leaf mouse is not obvious. But most people start with mice, which are difficult to distinguish because their sex organs are not so obvious. Here is a convenient method: male rats have hair between their genitals and anus because they are far away; Because the little mouse is close, there will be no hair between two o'clock. ?

As shown in the picture: the male mouse on the left and the female mouse on the right.
