I want to build a "cage" for my sons 2 leopard geckos.I plan on making it 25"l x 15"h x 15"d with a tile floor.My question is are there any problems using heavy plexi glass as opposed to shatter proof glass.Also shold I put anything under the tile.I am not sure how I would regulate the temp. of the under tank heater with the tiles.Any input would be appreciated.
