Another thing that helps for calm prey is raising your own rats and actually taking time with them and handling them at least on a weekly basis for a minute or two. We like to hold them and give them a small treat at least once a week then put them back in while they are finishing the treat.

Now then you go to feed the rat you take one rat to prescent the room, but this one will be to crazy to be fed because it has already sat in a strange environment for 20 minutes or so. Then as you pull your feeders out you pet them give them a treat and sit them in the opposite corner from the snake. They never even realize they were in trouble!
