Not really. Pregnant hamsters are really active and jumpy when they're expecting. :P
Most hamsters are pregnant for 16-18 days.
A Roborovski hamster is normally pregnant between 20 and 22 days. Some sources say that they can be pregnant for up to 30 days, though. Roborovski hamsters can be weaned at 21 days, and this is normally a good time to separate males and females.
yes! They normally only live about 2 years so one and a half is ideal for breading!
No. Hamsters, like all mammals, require sexual reproduction in order to get pregnant.
