first of all, you need a male and a female. a hamster comes into season every four days, so the only way to make sure they mate, you need to put them together for around ten minutes each night. if the female attacks the male, then she is not ready to mate. if you repeat this for four days, then you can be sure they have had the chance to mate, and be sure the female is pregnant. the female may not be pregnant, but this is very unusual. if you are unsure, then wait 18 days, as this is the average time the female is pregnant for till she gives birth. if she doesn't give birth, then mate her again.
