Last night, I got a new rat. His name is Hatchworth and he's a grey Berkshire Rex and 3-4 months old. The pet store labeled him as Hairless, though he is clearly covered in fur (albiet thin). As I've been petting him, I've noticed that his fur is coming out very easily and in small patches. Is he molting, and will it stop? Or will he end up being fully hairless/ a patchwork rat?
