top secret
I just went to a menards and bought 4 wooden screen doors, this way they would all measure to the same specs and i just drilled three of the sides together, fastened with screws. Then i attached plywood to the bottom and attached lenolium tiles to the bottom so water wouldn't get through and warp the wood. On the fourth door i used three hinges to make a door that swings open, the enclosure is large enough that i can actually walk into it, being that the cage is 6'7 X 3' x 3' . On the top i bought aluminum screen because aluminum is heat resistant, so the light and heat can get through the screen, but if my cham decides he wants to climp upside down in the cage, he won't burn his feet on hot metal. The whole cage costed around $75 to make and was a very fun project. I'm saving money to really deck out the inside of his cage.
