Breeding and reproduction in hamsters, as in other animals, may be a natural, easy process or may undergo serious complications resulting in an inability to reproduce successfully. Breeding females, for example, may have smaller litters or become infertile as a result of old age, malnutrition, a cold environment, not having enough nesting material, and not having a normal estrous cycle. However, infertility problems can occur in both males and females.
Pregnant females have also been known to abandon or eat their offspring. Though the underlying reasons have not been studied thoroughly, there are a few theories. A poor or improperly balanced diet, for example, may cause the female to look for nutrients elsewhere. Also, a crowded or noisy environment or excessive handling of the young may lead to abandoning.
