I got one for Kal El. He loves it. I bought a bird cage stand to hang it up on. The only problem is it's very hard to get him out. The door is way down at the bottom and the little door on top is too small for me to take him out through. My hubby make a "skeleton" to go inside to give it more stability and for Kal El to hang out on. He also added a round bottom piece for the bottom that he skewed the inside skeleton to.
I have one, don't think it's the large, not sure though. It's pretty big to a young chameleon though. They're pretty cool. I originally bought it for mantises, but ended up using it as a carry cage to bring my first Cham home in, and to the vet. Will probably be good for a quick trip out in the sun for Zelig, if the weather hurries up and gets warm before he's huge, that is!!
I wish it had a bigger door though, I originally when i got my first chameleon, i bought a plant to put in it that would have fit the bottom perfectly, but the door was too small to get it in.
