How Long Can Hamsters Live?

The life expectancy of a hamster can vary depending on its health and quality of care. On average, a hamster will live between two and three years.

  1. Maximum

    • An unusually healthy hamster may survive to twice the average life expectancy: five to six years.

    Breed Influences

    • Some domestic hamster strains, including popular breeds like the "teddy bear" variety, are inbred and more susceptible to disease, so they live shorter lifespans.

    Health Care

    • To maximize a hamster's life expectancy, it should be kept away from strong fumes and other irritants, and its cage should be cleaned very regularly to minimize exposure to ammonia and waste.

    Stress

    • Wet bottom, a form of stress-induced diarrhea, is a common cause of death in hamsters. Excessive handling and loud noises can contribute to this deadly complication.

    Minimizing Risks

    • Injury and infection are common problems in hamsters, and should be treated promptly if they occur. Most small-animal veterinarians treat rodents.
