well, it's going in my reptile room which is closed off, but in no way "iguana proof" for all-day wandering. can't go any more than 7' wide because that's the width of the room, and the cieling is not even 7' high. The iguana I used to have got free roam of the room when I was home, but pretty much just slept and chilled out in the cage while I was working. At the time the cage dimensions were 5hX4lX3w... he only had about 1/3 of his tail left from his previous owners, and that cage was a HUGE size difference from the "Iguana Habitat" cage he came in.
OH, and heres a pic of him when I had him. He's checking out the Savannah monitor I was housing temporarily (the sav is now living with a friend who does educational classroom visits.). I really miss that guy, had a great temperment compared to alot of the iguanas I've met.
Oh and another one, he'd get to wander around the whole house for all afternoon, and a few times I'd go to get ready for bed to find a sleepy iguana on my pillow. I ended up putting a hammock pillow in his cage for him to sleep on instead of just the hard wood. All animals like having thier comfy spots.
