Mice how many babies

A typical female mouse can birth between five and 10 litters per year. She can mate immediately after giving birth, meaning mice can birth a second litter in as little as 25 days after the first. This cycle continues until the mouse dies.

The pups are born without fur, ears or the ability to see. These early days in the life cycle of a mouse are filled with rapid progress. On the fourth day, their ears are fully developed. Hair begins to grow around the sixth day, and by day 10, they have a protective coat of fur. On the twenty-first day, weaning occurs. At 6 weeks old, the female house mouse is sexually mature and ready to start producing pups of her own.

This quick maturation process gives mice immense breeding capabilities. Once they are fully grown, mice will begin their search for food. Despite their small size, mice eat 15 to 20 times per day. While they primarily feed on plant-based material, house mice will also eat meat and dairy products they find inside the home. Sometimes they will even eat their own droppings to acquire nutrients produced by bacteria in their guts!

Living indoors, mice can reproduce all year round, but outdoors, breeding occurs during the spring, summer, and fall. Winter becomes too cold for mice to reproduce outdoors.

Mice also have longer lifespans when living indoors. It seems no matter how hard you try, there are always more mice than you can keep up with. How is this possible? Are they magical little creatures? The truth is they have amazing reproductive capabilities. These little guys reach sexual maturity at weeks of age. With a short gestation period of just about three weeks, one mouse can give birth to babies. A typical female mouse can birth between five and 10 litters per year.

She can mate immediately after giving birth, meaning mice can birth a second litter in as little as 25 days after the first. This quick maturation process gives mice immense breeding capabilities. Living indoors enhances these capabilities, since they can then breed all year long. Outdoors, breeding only occurs during spring, summer and fall.
