Reproduction: Hamsters breed throughout the year in captivity, while they are
reported to breed once or twice in wild. Maturity attains at 6-10 weeks of age.
Estrus lasts 4-5 days. The females (e.g. common hamster) become receptive to
males at 6 weeks of age and drop young at 8 weeks. The number of young produced
by a female varies from 6 to 12. Young are blind and naked. The normal lactation
lasts for 3-4 weeks.
Behaviour: Hamsters are solitary and "nocturnal in the wild. They are very docile and gentle pet animals, though their wild counterparts are reported to be exceptionally aggressive in nature. They usually live in burrows. Hibernation takes place during winter months. Territories are formed by the secretions produced from the glands. Another important behaviour is that these animals use their front paws for bringing food materials into the cheek pouches. Immediately after mating, the female builds a nest in the burrow. Cannibalism of pups is common especially in first litters among hamster.
Life span: They are known to live for 2-4 years.
