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.
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!
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.
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!

Koalas usually produce just a single offspring each pregnancy. Twins are very rare.
You should not disturb the mouse at all. Leave her with her babies and let them bond and get used to each other. After three days, you can then look and pick up the baby mice, but remove the mother mouse from her cage, or she'll start moving the babies around.
Just one at each pregnancy
ranges from 6 to 10 It can depend. The first litter tends to be smaller, usually 5-8 babies. Each subsequent litter tends to be 6-10. But this does depend on your mouse - one of mine gave birth to her very first litter just today and there are 11 babies! That really is unusual!
Yes. Each breast will usually gain about two to four pounds during pregnancy.
one for each baby usually. if it is a healthy pregnancy
Yes!Every pregnancy is different.While one pregnancy may come with little to no symptoms another pregnancy could come with every symptom in the book.Labor is also usually different each pregnancy.
An average cow will usually have one calf per pregnancy but occasionally she can have twins, and triplets very rarely.
each pregnancy results in between 1 and 3 baby hippos
Mouse mothers can have 5 to 10 separate litters of mouse 'pups' a year. The number of pups averages between 10 and 12 pups in each litter, if the mom is healthy and has plenty of good food to eat.
The mom will let you know usually they will start to fight each other.
the mechanical part of a mouse can be seen as the driver of direction in a mouse.
