also how many litters can one rat have in one year on average?How long after impregnating the female rat till she has her kittens?
Gestation in the mouse normally lasts 19-21 days
there are often problems if the pregnancy extend for more than 24 days
Most rats will either have their babies at night or early in the morning and expect litters of around 12-15 .
you can breed her again 6 weeks after the previous litter was weaned...
HOWEVER most experts say they feel domesticated rats should only be bred 3x in their lifetime IF that often.
(Remember they only live 2-3 years)
so birthing can be taxing on them.How long after impregnating the female rat till she has her kittens?
Usually 21-23 days before they are born and they have 8-12 babies on average
It will take around 29 days for the rat to give birth and about 6 litters a year. The range of babies can be up to 12 at one time.
