I have an idea now on what to do. Few follow up questions that came to me now:
1. I always put the lamp above the water dish. The idea being that the heat evaporates the water giving the humidity needed inside. I assume the UTH will go under water dish area of the tub for the same purposes?
2. I have always used aspen type substrate for my ball. I've read alot about using newspaper as it is cheaper and easier to clean. Just once concern about it is the ink. I know some newspaper have rather cheap ink. Like after holding/reading for awhile you'll get black inked fingers. Might this be a problem or health risk for the my python?
