all of the breeders that i have now are tame and friendly, but i bought them when they were just weaned and raised them with a lot of handling in attempt to assure that they would be that way. i used to have one female that was originally purchased as food and wasn't eaten before she got too big and i ended up keeping her and breeding her. i never really handled her so she was very skittish. right before she gave birth to her first litter she turned mean on me and took every opportunity to bite the living crap outta me. i understand being protective of her babies and all but she was a little much! she gave me the worst bites i've ever had from any animal. needless to say she is no longer with us...
