Ratty Age Calculator

Just for fun - how old is your pet in rat years?


This calculator is based on a comparative age chart compiled by Debbie Ducommun of The Rat Fan Club.

The relationship between rat years and human years does not follow a constant ratio - rats develop much more quickly than humans in their early life, so the calculator shows them ageing much faster at the beginning of their lives. The remarkable age of 7 for a rat is taken as comparable to the age of 130 for humans, based on an entry in the 1995 Guiness Book of Records where a rat called Rodney was recorded as living for 7 years and 4 months.

Guiness Book of Records 1995, page 32

If you take a look at this Life Expectancy Survey, you'll see that our pet rats generally live about two years. Much less than their potential age.
