I am not a mouse breeder, but got two mice that were both supposed to be female from Petco, and they had babies. Before we seperated the two, Mom had already gotten pregnant again and had another litter. I have a total of 20 mice now. 10 are still pinkies (about 5 days old), Mom is black and dad is white. The pups from the first litter are brown white or black, about 4 weeks old, there are 5 males and 3 females. I live in a tiny apartment and now have 4 separate mouse cages and don't know what to do with all these mice!
Please respond if you can take any mice.
