How many babies can a rat have?

Answer 1

The average female rat will have to about 5-15 babies. But, I've seen litters as large as 5-25. And i've seen litters as small as 1-2. But the average is 5-15. My female Rat had a litter of 12! :D
as much as 15000 descendants in a year
They can have anywhere from 1-15 (in very rare cases 19-20)
Rats can have from 1 - 20, though normally about 5 - 12

If your pet rat is gonna have pinkies (the term for baby rats) i recomend that you give her lots of protein - egg soaked bread is a good one ... And lots of nesting materials - paper, small animal bedding, but not sented woodchips as they are not good for a rats health.

i hoped that helped :)
Generally, with their first litter, especially if they are young, female rats will give birth to about 4-5 pups. More experienced breeders can give birth to 15+ in one litter. On average, a fully mature female rat will give birth to 10-12 pups in one litter.
rats only have one baby at a time but in one session of giving birth rats can have about up to 9 to 12 babies.
My female mouse had 12 babies and she let all of them die except 3 -do not know why -maybe she know how many she could take care of at one time-
Rat can give birth up to 20 babies some of them can die when given birth. Don't touch them because the mother will bite your hand or kill the babies.
That can vary from just a couple to as many as a dozen or more.
average is around 7-12.

They can go as high as 20 (some times more)

They can go as low as 2.

Smaller litters are more common then large litters.

***Don't breed rats there are so many unwanted!!
