Hamsters(Most often you will find Syrian Hamsters in your local pet shop) like most rodents are relatively short lived averaging 2-3 years life spans. Adults will grow to around 12cm in length(5 inches). They are not social animals, and prefer to be kept on to a cage. It’s most likely that more numbers than 1 kept in a cage will lead to bloodshed. Forget about the 30cm -45cm(12-18inch) cages you see in the pet shop – hamsters are active animals and do best in a cage of at least 75cmx125cm (30-50) inches but more is better.
