I only have 1.1 mojave, 08 siblings. The male is very nice and actually a better feeder than the female who is also chocolate. She is a hisser though. Not a bad eater but occasionally skips and never eats seconds like him. They where produced on a breeding loan so the only thing I know about the mojave dad was that he was big. My Garcia line chocolate mom is a feeding beast (ate two retired breeder rats last feeding) and a little jumpy when first handled so maybe that is where the 08 mojave chocolate girl got her hissing from.
