hamster pregnancies only last about 2 weeks, and you won't notice anything for the first week. she will put a little weight on, start building a big nest and become quite guarding of her cage. clean her out a day or two before she gives birth but don't change her bedding at this point. when she gives birth you must leave her alone in a quiet stress free spot. don't clean her out for 2-3 weeks - let her get on with caring for the babies otherwise she may eat them. at about 4-5 weeks, you need to split the babies into the different sixes and put them into cages for females and males. by 6-8 weeks they will start fighting and can kill each other so at this point they will need separate cages. hope that helps. wheatgerm with water is a good food to put in a bowl when she's given birth and the babies can eat this also from a couple of weeks. good luck !!!
