Well, I've been feeding live full size mice. I use a feeding box which none of my animals seem to have an issue with. I have them in a full size 3 tier rack from C Serpents, their warm spot is about 90-92 degrees, and the rest of the enclosure is a little over 80 degrees. I left him in a dark room for about 3 hours with the mouse he killed, and he finally ate it.
