I would also like to add that as babies, they do very well in wooden boxes with screen tops.
We use a 4'x4'x6" wooden frame with chicken wire top so that the hawks dont get em.
Like my lady said, waterland tubs makes a land tortoise enclosure, but is not very big, def not big enough for an adult. A baby, sure.
I know Raul uses a wooden frame very simliar to ours, and I think we both have had great sucess with them.
