It all depends, a rat can have up to 20 "kittens" a litter. This doesn't mean it will though, my rat had 10 babies. Hope that helped!
i recomend not to when they are young but you can when they are much older it is completely safe!
A pup is what a baby rat is called.
The rat does give birth to a live young but at a consequence. When the rat gives birth the young is trapped in a poisonous sack just like the placenta. The rat will free its young by eating its own poisonous sack, but will die due to the build up of acid. The young will then feed on its mother to get strength.
Yes. As long as they are the same gender, or one is neutered. Males are harder to get together but can be done. Females are easier. Old rats to young rats is easy, but the older rat may get annoyed by the younger ones. Adult to old / young is still easy, but the adult may be territorial. If neither of the rats have seen/met another rat before it may be harder. But if the older rat has met others before it should be easy - If you do it right.
