Dumbo rats are a breed of domesticated Norwegian rat that, like other rats, have an average lifespan of two years and a maximum life expectancy of seven years with excellent care. The Dumbo gene, responsible for the breed's distinctive large ears, has no effect on lifespan or general health.
Several factors affect whether a rat will live out its expected lifespan.
