I think there are alot more wiser choices out there than a Green Iguana. There are thousands, if not more, in rescues that are unwanted, so why contribute to the importation of these guys? Look up some rescues if you are seriously wanting to get one. You will do the rescue, as well as the lizard, a big favor.

If you want a lizard-type animal, why not a Yellow Ackie or something? They don't get as big(2.5'-3') and don't have the horrible attitude that the Iguana does. There are Bearded Dragons, Cresteds, Uromastyx, etc. You can get a Captive Bred and Born animal that has been properly taken care of, rather than a baby iguana that has been shipped over in a box with hundreds of others that may be sick, parasitized, or even dying(or already dead).

Uros are neat as they come in gorgeous colors and are also a vegetarian species. Cresties also come in many different colors/patterns, they thrive in room temperatures, require no expensive UVB setup, and are funny to watch. Bearded Dragons are hilarious to watch, and are omnivorous. They do require UVB lighting and a good-sized enclosure(4x2x2-like Uros), but are very rewarding and seem to like to be handled.

All I am saying is that there are MANY many other choices other than an Iguana. You won't be spending hundreds of dollars getting the animal deparasitized, eating, the huge enclosure it will need as well as the expensive UVB lighting and other heating methods used to heat such a large enclosure. It would probably be more rewarding to get a quality captive bred animal that you know was taken care of properly before it got to you.
