I was just reading another thread and someone mentioned belly heat. I use heat lamps and put pieces of slate rock in the cages for my Iggy and Beardys, I heard that helps them digest thier food better. Is this needed for BPs? I have recently cut a hole in the top of Salinas cage and moved the light up and out, I also switched to a red light which she seems to love. She is a lot more active now. Should I put a piece of rock in to help her digest her food a little better?
