I just wanted to add, some ball pythons LIKE being snake turtles. A couple of mine in fact have so far outgrown their hides it's more like a snake hat, but if give them a bigger one they pitch a fit. Ball pythons are weird that way.

I use mainly plastic cereal bowls and plastic beverage tubs from the dollar store. they come in a wide range of colors and sizes, and they are cheap.
