Yeah, mice do fine with back to back pregnancys. It does tend to take it's toll on there bodies and the litters have to be weaned early. It's all a matter of how fast you need mice and how long you want your breeders to live. It technically doesn' t matter since by the time it really takes it's toll they're out of their breeding prime anyway.

Passing my male around has 2 advantages. I control how many pregnancies and I only have one smelly male around.
