Djungarian hamsters tend to have slightly smaller litters, as do Chinese and Roborovski hamsters. Intersexual aggression and cannibalism. Female Chinese and Syrian hamsters are known for being aggressive toward the male if kept together for too long after mating. In some cases, male hamsters can die after being attacked by the female. If breeding hamsters, separation of the pair after mating is recommended, or they will attack each other. Female hamsters are also particularly sensitive to disturbances while giving birth, and may even eat their own young if they think they are in danger, although sometimes they are just carrying the pups in their cheek pouches. They are completely weaned after three weeks, or four for Roborovski hamsters. Most breeders will sell the hamsters to shops when they are three to nine weeks old. Longevity.
