How Long Do Hamsters Live?

1 Hamster Lifespan

A hamster’s life is much shorter than a cat’s or dog’s; the average is about two years, so a hamster is adult at four months. Breed and sex matter: Roborovski hamsters are the longest-lived pet type, and males usually outlive females; among females, those that never bred live longer.

2 Factors That Affect Lifespan

Breed: Roborovski hamsters are the longest-lived among pets; if you want more time with your pet, choose a longer-lived breed.

Genetic disease: like a time bomb, it can kill at any moment and passes down generations; don’t breed a hamster that has a genetic disease.

Environment: hamsters are picky about their surroundings; a safe, comfortable, roomy and clean home helps them grow healthier and live longer.

Solitary life: co-housing causes constant fear and even fight injuries; living alone suits them and tends to extend life.

Food: keep food and water clean and fresh, especially fruit and vegetables — don’t leave them in the cage more than 24 hours.

Illness: colds, wet tail and injuries all harm a hamster; avoiding sickness lets it live longer.

A hamster’s life is very short, so cherish the time and care for it well. Consult an online vet if you have other questions.
