Short lives, fast ageing

Syrian hamsters, the most popular pet hamster, typically live 2 to 3 years, and dwarf species often live a similar time. With a typical lifespan of 2.5 years, one hamster year corresponds to about 32 human years – and a single month to more than two and a half human years.

Life stages

Hamsters are weaned at three to four weeks, reach adulthood at a few months old and are considered seniors from around 18 months to two years. Older hamsters often become less active, lose weight or get a thinner coat.

Making the most of a short life

A large enclosure with deep bedding for burrowing, a solid exercise wheel of the right size, a varied diet and a quiet routine help hamsters stay healthy and active for as long as possible.
