The average litter size a rat may have is anywhere in between 8 and 12.
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.
She buries her young.
basically - it doesn't ! Once the young snakes arrive, they are pretty much independent, and quickly disperse in search of their first meal.

I don't know the age but i know the bigger ones are adults and the smaller ones are younger.
Yes they do rats will eat mice in the wild. But tame rats will actually raise the young of mice when mixed in with their own young as the mouse grows up the rat accepts the mouse as one of its own and will not eat it. We did this while studying animal behavior. The rat was the only rodent not eat the young mice. We also tried the study with gerbils and hamsters and both found the young in the nest and ate them. These studies were preformed with orphaned animals in an attempt to save them from certain death. The ones with the rat as a parent grew and thrived right along with their rat siblings to a ripe old age.
One mouse or rat that is roughly the same width as the middle of the snakes body, once a week. More food is necessary for young/growing snakes.
unlike humans, there is little stigma in the animal world that would prevent a rat from conceiving upon reaching adulthood.
