Best Answer

A rat's tail serves two main functions:

1. The tail is useful in temperature regulation. As rats do not perspire, they have to use other means to regulate heat in the body. They are able to expand and constrict the blood vessels in their tails to allow more or less heat to escape from the hairless skin on the tail.

2. The tail helps in balance. Although we generally think of rats as scurrying around on the floor or in a lab cage, in nature they are rather nimble creatures. A rat is able to use its tail to provide balance when climbing branches, ropes, chains, etc. This function serves the same purpose as the tail of a cat or kangaroo.
