I have been trying to figure out how I can put belly heat on one of my cages and ran across the Kane heat mats. After some research, I found Kane Manufactory's warranty. It sounds and looks very durable; however, the warranty says not to cover it with ANYTHING. (I guess with the exception of their own covers ???)

Does anyone use these inside their snakes enclosure? Do you use any sort of bedding or newspaper with it? If so, have you ever had issues by doing so?

Thanks!
