Hairless rats have a strange appearance and special needs that are slightly different from the averaged furred pet rat. Hairless rats are bred from Rex rats, one of many rat breeds. Rex rats, which have a coat that's curlier and coarser than an average fancy rat, have one copy of the Rex gene. When a rat gets two copies of the Rex gene, he is born hairless. Hairless rats are sometimes referred to as " Double Rex" rats, a reference to the two copies of the Rex gene. Unlike many other "hairless" animals, hairless rats are almost completely bald. Most will have some fine, sparse fur near the nose, around the ankles, and on the tail, but otherwise, they're all skin. This hairless attribute means that hairless rats have specialized care requirments, different furred rats.
