Ok so we accidently on purpose brought home two rex boys, one dumbo one top ear, who are likely around 3wks old. We've never had baby rexes, our rex girl is an adult. So I am not sure if their fur is normal, if they are some other coat, or if they are potentially sick. Their fur is very thin, and it seems as if it may be getting thinner. It's easier to notice on Beelzebub then Baniwi as Baniwi is light colored. We have them eating soy formula soaked food, and I'm gonna cook them some egg. The boys seemed a little thin, we got two standard girls and both them seem plumper but they may be a bit older we don't know. They eat fine, drink fine, and climb and play great. Skiddish still but they are so young. I'll try and post pictures but is it normal for rex babies to have a thin coat? Or any type of rat? (They have curly wiskers and their fur is curly/wavy/kinky, however you want to discribe it.
