Thanks so much everybody! I got a lot of info! I have another question. How much could I sell the heat rock for? I better get rid of it. How much would you pay for it? It is in perfect condition. I just need some opinions.

He does have a overhead light, and also has a branch. I will tell my cousin all of the info that you have given me. Also I have another question.
He has a little pool in there that takes up some of the space in the cage. He dosen't give the igauna any more water besides that... I don't know what to tell him.
Also, he feeds his Green Iguana dry igauna food. I keep presuring him to give him veggies! He just says that he dosen't have time... Can you answer my questions?
All the info will be appreciated!
