The male golden hamsters should be first bred when they are 14 weeks old while the female as early as 10 weeks old. The best is to wait for the female hamsters reached four months of age as to minimize the chances of eating/destroying its own litter. It is always a good idea to breed hamsters of the same breed but make sure not to breed brother and sister hamsters. The father daughter or mother son combinations are usually fine. The next step is to make sure that your hamsters are healthy to prevent any spreading diseases.
Thin, stringy, cobweb-like mucus exits the female's vulva as the time of copulation approaches. The female is then placed into the male's cage about one hour before dark and must be carefully observed for mating activity and/or fighting. In this situation, the females can be very aggressive to males thus can harm them. Do remove the males at once if fighting occurs. If it is a success, the full term pregnancy will only take 15 to 16 days. Just before delivery, the female will become restless and usually discharges a small amount of blood from her vulva. The newborn pups are born hairless with its ears and eyes closed usually range from 5 to 10 pups. However, they do have their front teeth at birth.
The mother with young should be provided with abundant nesting and bedding materials and plenty of fresh food and water. They must not be disturbed in any way until at least 3 weeks old. Do not touch or handle the babies, disturb or clean the nest during this period. If you ignore these cautions (especially with females nursing their first litters) it often results in cannibalism of the babies.
