The average lifespan of a rat varies depending on the species and environmental factors. For domesticated rats, such as the common pet rat (Rattus norvegicus), the average lifespan is typically about 2 to 3 years. In contrast, wild rats tend to have shorter lifespans due to predators, disease, and other environmental challenges, often living only about 1 to 2 years. Some individual rats, especially those kept in ideal conditions with good care, may live longer, even approaching 4 years.
