Cute Hamsters

Golden hamster females are also very aggressive toward male hamsters and must be separated immediately after breeding in order to prevent an attack. Female hamsters are also particularly sensitive to disturbances while giving birth and may even eat her own young if she thinks they are in danger, although sometimes she is just carrying the pups in her cheek pouches.
Hamsters are born hairless and blind in a nest that the mother will have prepared in advance. After one week they begin to explore outside the nest. They are completely weaned after three weeks, or four for Roborovski Hamsters. Most breeders will sell the hamsters to shops when the hamsters are anywhere from three to nine weeks old.
Mating and longevity
Golden Hamsters typically live no more than two to three years in captivity, less than that in the wild. Russian Hamsters (Campbell's and Djungarian) live approximately 1.5 to 2 years in captivity, and Chinese Hamsters 2.5 to 3 years. The smaller Roborovski Hamster often lives to 2–3 years in captivity. Both Golden and Russian hamsters mature quickly and can begin reproducing at a young age (4–5 weeks), whereas Chinese hamsters will usually begin reproducing at 2–3 months of age, and Roborovskis at 3–4 months of age.
