According to what I have read, mice usually have litters of 8 -10, but can have as many as 17. The gestation period is 16 - 21 days, and they can become pregnant again immediately after giving birth, but that this is not healthy and the male should be removed prior to birth and not reintroduced until about 2 weeks after the baby mice are weaned to give the mother time to rest between litters. Anyway, by my math, if two adult mice are left together, they could have 34 babies in one month's time.
