Great find!

I'm taking care of the colony 4 hours 2x a week, 6 bags of rat crap to dispose of..
I was given the gift of a few double Rex breeders, and I am lucky for that. These things are up to 250g breeding weight in almost half the time as my others...

I read the only true hairless are genetic modified in labs, and double Rex was hairless.. But idk..
