i am in the process of making a new cage for my ball python the measurments will be 40L 20w 15h it will have a glass front thinking like 36x17 for viewing but everything else will be wood, i will have a hinged top to get into the tank, i decided to make the top hinged for easy access and cleaning. my question is "can i use a human heat pad inside my cage because a uth will obviously not work cause the bottom will be wood, im open to any ideas, i finally got my 20L correct and now i have to make all these new problems for myself, it will be worth it in the end though, my boy will have much more room to roam.
