I saw foot prints in his Calcium supplement dish and his his repti-vite supplement dish. I use papertowles as a substrate with removeable layers in his regular poop-corner.

All of my enclosures have digital thermo/hydro indicators(a few analog may be hanging around from 'the early days' but aren't my 'real' indicators).

They all have Ranco temp-controllers with Oregon scientific probes near the substrate for checking on them from across the room.
