I think iguanas are great, but I would never get one myself. They get too big. There's this pet store around here where I buy the worms for my lizards that has about 6 iguanas in a 3'x2'x2' cage. Ive seen the iguanas for a couple weeks now so I asked someone who worked there why they kept them in such a small cage. The lady said that they got new iguanas in every week and that the lizards were never in that cage for more than that. I think that's crap. One of them is well over 3 feet long and I am pretty sure that those igs have been there for about a month. I dont think igs sell THAT fast. They have a day gecko that has been there for over a year! If it didnt cost 125 euros, I would have taken it home already.
Anyway, I think it's irresponsible to sell iguanas and breed them. The only reason they should be bred is to sustain the species, not for pets. I would never trust a stranger enough to sell him an iguana. I doubt that most people take proper care of them and give them the needed space.
I have a friend with 2 igs. Her cage is about 6 feet high, 2 feet wide, and 2 1/2 feet long. I used to think that was big, but after reading so much about igs and water dragons, I know it is too small.
I keep hearing so much about iguana adoption. It is sad that these animals are being bred like crazy, yet are given up like puppies a week after xmas. If you have iguanas, do them a favor, DO NOT BREED THEM! It is irresponsible and egotistical.
Take good care of the pets you have, adopt if you can, but dont buy any more from pet stores!! That only adds to the problem.
