Not really. I'd avoid glazed tiles or smooth tiles like that because the dragons will have trouble getting traction on them. Tile that feels slightly rough (not sandpaper rough, but like unglazed ceramic) would work well to provide plenty of traction (and keep nails trimmed).
Thanks. I figured it worked the same way as we humans do. I did research before i went with it.. and because it so thin and such small pieces then can actually digest it without a problem... but I feel like i will be getting a lot a **** from people if i dont change it out...
I'm drawing on my experience from caring for a dragon and from reading this forum every day. I'm absolutely not an expert, just sharing my opinion and experience. There are a lot of good, experienced voices on here who all care a great deal about dragons. Lots of thoughts and opinions. Read as much as you can and then do what you feel is right for your dragon. =)
