What is the average lifespan of a rat?

Answer 1

Rat live an average a 3-4 years. When I use to breed them I did have on live for about 4.5 years (big old male, and what a good friend he was).

Another interesting fact about rats is that they are the only member of the rodent family smart enough to not bite you (Stressed point: if hand raised. aka handled often) even if you smell like food. (make sure to feed them regularly)

Answer 2

From about 26 months if the rat is living in a confined space with bad nutrition, like lab rats, or up to48 years if the rat is lucky and healthy. MY rats have lived for 3 years so far and they aren't slowing down!

Answer 3

Depending on if it is still in the laboritory or not.

A lab rat taken into a pet home can live as long as 2 years, even 3. A lab rat that is still in the laboritory will live for however long their carers wish to have them living.

Answer 4

The lifespan of a rat is 2 to 3 years on average.

Answer 5

The life expectancy of a Domestic rat is about 2 to 3.5 years.
