== == They can have anything between 7 - 20. Our school rat had 16.
5 to 10 if it is the first littler, after that anywhere from 10 to 20
Rats can have up to around 10 pups in a litter, but the doe's (female's) first litter is usually smaller. Maybe around 5-8.
Rats can have 8 litters a year with up to 20 babies in the litters!!!

how many litters do hyenas have in a year
The average female Norway rat has four to six litters per year and may successfully wean 20 or more offspring annually. The average number of litters a female roof rat has per year depends on many factors, but generally is three to five with from five to eight young in each litter. For more information about rats, breeding, habitat and control, please check out my bio.
how many litters per year does a potbelly pig have
Penguins do not have 'litters', they lay eggs and usually lay one egg a year.
once per year
Female rats can get pregnant, generally, from 5 weeks old onwards. If they are left to have back to back litters (get pregnant, give birth, mate with a male within a few hours of birthing), then they will have 1 litter every 19-25 days, so there being 395 days in a year, that gives you as many as 20 litters per year. As for male rats, it would depend how many females they managed to get pregnant, for example if a male got 5 girls pregnent, you just go 20 x 5 = 100.
During a Boxer's whole life, she can have two litters a year after the age of around nine months.
Once
That is quite normal rats/mice can have as few as 3 or as many as 20!

In a female rat's lifetime, they can have around 5 litters, each litter having atmost about 14 babies. So that's like around 70 babies per rat's life!
Around 30, if they get lucky.
