No they are not like Retics. Unless Kev has some info hes keepin from us anyway. I breed them and from talking to people that do they can all be tamed. From WC adult animals. . they may not be tamed to exactly like you but to tolerate you. As for CB babys, you can play with them and make them as nice as any leopard gecko you will ever see. Just takes time and lots of working with them. Its also how you treat them. If you just go in and grab them then yeah they will bite you, if you gently pick them up they are alot calmer.
