It depends on what hamster you have. Usually they are pregnant for 2 weeks. 14-16 days. If your hamster is pregnant for 20 days or over, like most people say, then there must be something wrong. I have 2 hamsters. A boy and girl and the girl has had babies 3 different times. Working on 4. So, I am pretty certain that a hamster has its babies in early 3 weeks after the mating. If your hamster is having babies, and you don't want more. Seperate the boy from the girl. After the girl has her babies she gives out this fuem kind of thing that attracks the male, and in another 2 weeks you will have babies. If you have a hamster, they usually have up to 10 babies.
about 2-3 weeks
A hamster can have up to 16 babies at once but the average hamster has about 3-10 babies
As early as a couple months, even weeks! Unless you can find homes for many, many, hamsters, I would suggest not putting a male and female hamster together.
If you are asking can a hamster have triplets, then the answer is yes. The average litter for a hamster is anywhere around 2 to 5 babies, but some hamsters have had more than twenty babies. However, how many babies your hamster has can vary from hamster to hamster.
From 1 to 5 babies.
Count them.
