I've posted my story here: http://www.herpcenter.com/green-iguanas/26597-new-guy-rescued-iguana.html He's been in my dining room since I first got him about a month ago. I moved him into his new house yesterday morning, but he has hardly moved a muscle. It's six panels bolted together for easy transport - I actually built it in my workshop, then took it apart and put it back together upstairs. Tan showerboard panels with 1x2 pine frames, seams are all caulked. The floor and ceiling are made of poplar and plywood also covered with showerboard. Melamine shelves and wire closet shelves for ladders. You can't see in the pics but there's a warm mist humidifier plumbed into the side below the window with 3" pvc pipe. 160W Megaray and 40W night lights in 6" recessed light fixtures on a timer, plus a ZooMed Hygrotherm that control a separate 150W ceramic heat emitter and the humidifier. There are a couple of 2x8 vents (one on the bottom left and one on the top right), but I had to close them both to get the basking spot temps up to 95F. I think there is plenty of airflow, though, since there's a good 1/8" gap around the door and the light fixtures have holes in the cans to let the heat out. I can't get the humidity higher than 55%, but I want to get a separate hygrometer to verify since it seems really muggy in there... Oh yeah, inside dimensions are about 45" by 48" and six feet high.
