average life span of a rat
Lifespans of Fancy Rats. The common pet rat wonât be as long lived as many of our favorite pet species. This can deter new owners, as it is shocking to realize that pet rats will only live for 2-3 years on average. Usually, they live for 2.5 years, or 30 months. Yes, THIRTY months. Thatâs a really short lifespan for rats, as amazing of pets as they are.
