I put a piece of nice branch/like log thing for snakes. All natural, and my purple passion has a ritual of eating and hiding in his warm hide on Tuesday, then on Sunday and Monday when he knows he getting fed soon he balls up on the top of the branch and waits for me to feed him. I have a small 25 watt bulb that shines down on the branch and he loves it. He has done this for the last 3 weeks lol
