How large can a mouse colony end up at?

A mouse colony can grow rapidly under ideal conditions, with a single female capable of producing up to 10 litters per year, each containing 5 to 12 pups. Given that mice reach sexual maturity in about six weeks, a colony can potentially swell to hundreds or even thousands of individuals within a year if resources are abundant and there are few predators. However, factors like food availability, competition, and disease typically regulate their population size. In practical terms, a wild mouse colony might reach several hundred individuals, while in controlled environments, it could exceed thousands.
