How Many Babies Can Mice Have at One Time?

The population of mice in one house can quickly become very large. Mice have babies in litters as do many other mammals. By the time you see one mouse, there are several more close by.

It takes a mouse about three weeks to carry a litter to term. Each litter is usually about six pups. And the female can get pregnant almost immediately after giving birth, meaning a mouse can have a litter of 6 mouse pups every 21 to 25 days.

A mouse can begin to reproduce when she is between 6 to 8 weeks old. And she can give birth to about 35 babies in a year. If only half of those babies are females, you could expect to see thousands of baby mice born in a year in one home.

What Do Baby Mice Look Like?

Baby mice, called pups, are born without hair or ears and are blind. Being underdeveloped, they remain with their mother for three weeks before living alone. She will care for them, keep them clean, and nurse them. After a few weeks, a mouse will grow their hair and ears and begin to look like a smaller version of a full-grown mouse.

How Long Do Mice Live?

Like most animals, the lifespan of a mouse will depend on its surroundings. A mouse that lives inside a house with access to heat, water, and food, could live up to 2 years. They could give birth to nearly 70 babies in that timeframe.

A mouse living outdoors without regular access to food, water, and shelter only lives half as long. They can survive up to a year in those conditions. But even in that amount of time, they can give birth to a lot of offspring
