Why? My snake is receiving enough heat on the warm side both during the day , and at night. The heat being generated from above actually warms his hide and branch, and he often basks on top of them. Do snakes require belly heat for digestion. I kept Green Iguanas for 7 years and I know that they DO require a direct source of heat to activate bacteria in the stomach that aid in digestion. Are snakes similar in this way? If not, then why is it a must for them to receive a heat source from directly below?
Not trying to argue, I just want to understand. At the same time I have nearly optimal temps and humidity, with the exception of wether or not to have a UTH mounted underneath.
