How many babies does a mouse usually have each pregnancy?

Answer 1

Anywhere between 1 & 20, though commonly litters of 8-15 are pretty regular. Super mice & some feeder mice are bred to have large litters (13+) & some shjow & pet types will have about 8 or less.

Answer 2

A mouse normally has 10-12 babies. Mine had 10. One mouse reportedly had 17.

Female mice can become pregnant again immediately after giving birth, also. Assuming an average litter size of 12, a single male and female pair can create well over 140 babies per year. This doesn't include the offspring their children create, as baby mice are fertile at just one month old. Phew!

Answer 3

Somewhere around ten, as long as the mouse has not been inbred. If she has been (such as with her brother, father, etc.) she will likely have a very small litter, about 1-5 mice. I have seen litters as large as 16, though 10 is the average.

Answer 4

They average about 12 babies per litter, but can have as few as 2 or as many as 14 at one time.
They usually have up to 25 at a time!
