How Long Do Rats Live?

The typical lifespan of a rat is two years. The typical lifespan of common wild rats (brown and black rats) 

is one year. Because of the greater risks they face in the wild, they have a shorter lifetime. 

Although they can live up to seven years, pet rats often only survive two to three years. Because they are

protected from predators and have access to food, they live longer. Rat pups are entirely reliant on

their mother from birth. Rat babies have short tails, no hair, and are deaf and blind. It takes them a week

to be able to walk. After two to three days, the ear canals open. Their eyes open seven days after birth as well.

In their first two weeks of life, rats are primarily sedentary. This is to ensure that they develop and put on weight.
