He is sorta cute......... He needs a sweater or he'll catch a chill! I had a hairless mouse once and they feel really cool but not so nice to look at.

This is another website the described a double rex rat. http://www.paperheartrats.com/varieties.html (Scroll down a lot!)Hairless, or Sphinx rats are a coat variety characterized by their complete lack of hair except for the whiskers and perhaps a non-standard small patch near the top of their head. Semi-hairless rats, bred from Rexes, have varying areas of bare skin, or very short fur on their bodies. Because the Rex coat is a dominant trait, it only needs one Rex-parent to affect the rat's appearance. However, when two copies of the trait appear, by breeding two Rexes together, the coat is affected differently—causing semi-hairlessness, and earning the colloquial name, "Double-rex". Semi-hairless varieties are produced by different combinations of the various genes that cause Rex coats. One subset of semi-hairless rats, patchwork rats, constantly lose hair and regrow it in different "patches" several times throughout their lifetimes.
Double rex is when a rat gets two copies of the rex gene - one from each parent. They start to go bald at around 3-4 weeks old and after that they continue to shed their fur in very interesting patterns! Others will keep a fine coat of fuzz throughout their lives and sometimes double rexes are virtually indistinguishable from true hairless; it's always a surprise how they turn out! Sometimes these rats may be referred to as "patchwork" because they will have patches of fur in some spots and bald spots in others. I have double rexes very infrequently but always enjoy watching the changes they go through as they grow!
