I agree with you. If you have animals that burrow, which mine do not, this is not a good idea and I mentioned that in my post. Not all ball pythons burrow down into their substrate. Also my animals do not slosh around in there water nor is it anywhere near this pad. The whole peeing on an iron reference to make me sound dumb is a little much but I always take what everyone has to say with a grain of salt. What works for me is good for me and what works for you is good for you. It was a suggestion. He came here and posted his thread for that reason. I am by no way saying my way is right but it has worked for me so I thought I would share. Just as you have.
