They're not actually hairless, as they have a fine dusting of hair along the entire length.

It's a adaption to allow rats to pump large amounts of blood into the veins along their tails to cool their body temperature down. It's quite effective.

True hairless rats (they have no whiskers) are rare. The type you are likely referring to are those that are bred from two rexes (curly haired rats).
