I recently got a ball python, we assume he is about 2-3 years old and is about 4-5 feet long. We actually just brought him home today. We have the tank all set up, still working on adjusting everything now that he is in there. My general question is how think should the bedding be? I am worried that we have it too think and he cannot feel the UTH, but I also worry that if it is not thick enough he will get burnt. Any suggestions?
