You might be able to foster the babies with another nursing mouse, or even a female mouse who isn't nursing--mice are able to lactate when needed, but it might take awhile for that to kick in. You might have to foster the babies yourself.

Not really... the male mouse will probably mate with her shortly after she gives birth and this can put stress on the mother, and could cause her to eat her babies.
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.
No way. If the baby mice are in the cage long enough with the mother mouse, the mother mouse will indefinitely eat the babies.
usually not.
Female mice will mostly have from 6-12 babies at a time. Some Female might have more or less than that. There really is no right answer to this.
Yes, mice can have 2-14 babies. But when you breed, you usually get 4,5,6,7 babies. In rare cases, a mother mouse can have up to 20 babies!
Yes.
no. the mother mouse would only kill its baby if it was dead or sick! if the others are healthy she will not kill them.
If your mouse has babies, leave the mother mouse and her babies alone for at least three days. After three days, you can clean out the mouse's home, and pick up and hold the babies. Keep cleaning the cage every six days or so, and make sure the mother has plenty of food and water. After about four weeks, you can begin sexing and separating the males from the females.
Buy a new Mouse.
No! Any male mouse or rat will eat any mouse babies. dont let male mice with babies until they can see and have fur!
Rats might abandon their babies if they can't take care of them or if they are too stressed. My rat had babies and it kept abandoning one of them. We tried to feed it, but then decided to take it to the pet store. They put it with a mother mouse and it started licking it. A few days later we visited the pet store again and they said it died. If your rat abandons its babies, feed them with soy milk.
