ACQUIRING A HAMSTER :: HAMSTER AGE
When seeking a pet hamster for the first time, the most important thing is choosing a young hamster so that you can tame the hamster more easily and also enjoy the hamster companionship for as long as possible; since hamsters are short-lived pets, with a typical life expectancy of 1-3 years. On the other hand, if you owned hamsters before, an old hamster is an excellent choice too!
When acquiring a hamster, it is also important to take into account the age of the hamster and the number of hamsters required. The Syrian Hamster is a solitary animal and once it has reached maturity, it will not tolerate the company of another. A Syrian hamster should always be housed alone; one per cage. For a first timer, we recommend a Syrian hamster since it is easier to tame and it is larger in size.
So, if more than one hamster are required and you do not want to purchase another cage, a Dwarf hamster or a Roborovski hamster are the answers. Dwarf hamsters are social hamsters and will live happily together in single sex or mixed sex pairs or groups. Obviously it's better housing Dwarf hamsters of the same sex since, if they are of different sexes they will reproduce. Roborovski hamsters can also live in groups.
