Mice can reproduce incredibly quickly! Here's a breakdown:
Gestation Period: A female mouse is pregnant for about 19-21 days.
Litter Size: They can have litters of 4-12 pups.
Frequency: A female mouse can become pregnant again almost immediately after giving birth.
This means a female mouse can have multiple litters in a single year. It's one reason why mice populations can explode so rapidly.
Keep in mind:
* This is a general guideline, and individual mice can vary.
* Factors like food availability, shelter, and predation can impact how often a mouse can reproduce.
