Moni! Your rats are super beautiful! They make mine look like little mongrels! I think Despearoux (sp?) is coming home with me. His coloring is so nice! The Pink Eyed White is also super cute! They all are!
ZC- Hairless aren't born furry, all rats are born naked (hence the reptile owners' term "pinkies") and most start growing fur around a week old. But when you breed a rex coated rat to another rex, you get doubles rexes, and they grow a full coat by around 2-3 weeks, then slowly loose it again. (There are other circumstances where a double rex can be produced, I think) At adulthood, double rexes can have varying amounts of fur. My girl Mambo is a DR, but she has very little hair.
Moni, it's funny that you have a hairless named Tembo. My next girl rat is going to named Tempo, to go with Mambo.
They'll have to be little rat friends. It'd just be too cute... Tembo and Tempo.
