The females could breed well beyond the 12 month mark, but litters would begin to drop off in numbers. My first females began having litters at about 3 months of age and more at 4 months of age. I probably would have raised the females so that they wouldn't have a litter before becoming adults, except I was having trouble determining the sexes, and by then it was too late. That wasn't all bad though, as I have lots of babies already. LOL. These guys seem to eat a lot more than my previous mouse colonies did.

I can't really complain about their growth rate, as mine seem to grow fast on a diet of 21% dog kibbles, guinea pig food, carrots, and apples.
