I know this is an older thread but I wanted to address the OP's question. I have a regular black ratsnake (albino). I got her when she was a hatchling, she's now about 9 months old. She is extremely gentle and docile. She's also very playful and curious. I have seen videos of aggressive ratsnakes, and I'm sure there is an inborn personality factor .. but the key is to hold them daily, and especially get them used to lifting up the hide and taking them out so they don't feel threatened by this. My snake has never snapped at me, "rattled' her tail, or musked at me.
