So for my dragon I've been using the Exo Terra sand mat. I shake it off before putting it in Pickles home to make sure any loose stuff comes off. I like it because it help wear his nails down. Now I'm being scolded that I'll kill my dragon with it and should be using reptile carpet. My question was won't his nails get caught in the carpet? So is the sand mat bad? Thoughts? I'm not a fan of tile because when I put Pickles down on my tile floor he slides and just stops moving and his beard gets black until I pick him up.
