Hi! I've got a new cage for my uro, and I'd like to make a nice background for her. That is, a background that goes inside the cage, something for her to climb on etc. Not the kind of just decorative background that goes on the outside of the tank. I was thinking about making one out of styrofoam and then coating it with something so that it 1) gets stronger and 2) she wont be able to dig all the material out. Does anyone know of a non-toxic paint to use for this purpose? Or do you have any other ideas? Also, i was wondering if there is any good way of coating such a background with sand. I tried to do it with the kind of wallpaper glue you make out of starch and water (should be completely harmless, I think), but it didn't work out too well.
V. greatful for any help!
