just finished up a monster of a bearded dragon cage. Its 6ft long by 4 ft deep by 2 ft tall. The rock background was made with great stuff, tile grout, a textured spray paint and protective coating of polyurethane. The Wood used on it is 1/2" ply wood with a 2x4 frame thats been hidden by the rock background. The bottom is lined with a roll on truck bed liner for moisture resistance and the substrate is masons sand, ive built a raised feeding platform thats roughly the size of a 30 gal aquarium and lined that with repti-carpet for a safe eating area. The doors are actual vinyl utility shed windows and the front half of the top also opens for easy access to the entire enclosure.
