So I always wanted to have a double rex rat (the hairless one) and I'm preparing to get one, but do they require special care for their skin? Or do they get cold easily? I saw some people putting sweaters on theirs but I'm afraid it would just chew it and take it off. I just don't want them to have skin issues just because I'm doing something wrong. If anyone knows about it, i would appreciate the help!
