You don't, breeding mice is unnecessary. Moreover, they breed so quickly that it would be far too easy for the situation to get out of hand. Please do not try to breed your mice.

do you have a male there too because one female mouse can't breed if there is no male in the cage? maybe they are fighting.... or maybe the pet store or you got the breeds mixed up....maybe its a male or something. IF IT HASN'T BEEN 21 DAYS AND SHE HASN'T GIVEN BIRTH OR IS PREGNANT OR LOOKS PREGNANT......GET ANOTHER FEMALE MOUSE AND HOPEFULLY IT WILL BREED.
Yes, you must have a male and female to breed.
Male and female mice can breed from as young as six weeks !
i have 16 mice and only one huge male is biting a tiny female. She's bleeding... and all i can guess is causing it is that he doesn't like my scent on her because to him it might seem like its a new mouse every time. Either that or they're just trying to breed, only the female isn't in heat and the male is overly aggressive. i would either separate the male from the female or try not handling the female as much.
If you breed a female Skitty and a male Wailord then you get a Skitty but if you breed a female Wailord and a male Skitty then you'll get a Wailmer.
