House mice usually live less than one year in the wild, due to a high level of predation and exposure to harsh environments.
In protected environments, however, they often live two to three years.
The Methuselah Mouse Prize is a competition to breed or engineer extremely long-lived laboratory mice.
As of 2005, the record holder was a genetically engineered mouse that lived for 1,819 days (5 years, 39 days).
Another record holder that was kept in an enriched environment but did not receive any genetic, pharmacological, or dietary treatment lived for 1,551 days (4 years, 90 days).
