I recently bought 3 baby hermann's tortoises. I have them in a 5' x 3' enclosure on a newspaper substrate. Twice now I have found 1 or more of them flipped over--today it was under the basking light. They are usually in the middle of the enclosure--there is no furniture for them to flip on, so I am guessing they flip over on each other. Anyone have any good ideas on substrate I could use that would allow them to right themselves if they flip over? I heard bath towels are good, and I am seriously considering that. I was also thinking of putting some pieces of tile in the enclosure for better footing.

Any help would be greatly appreciated
