OOPS Just found this thread..
As for the Iggy #'s in rescue..I do rescue with them and get called on about a dozen per month. I know of other rescues that get an average of 20 or more per month needing new homes. Iguanas have teeth that arelike shards of glas in their mouths. Not only are the teeth an issue but also their tail too. The tail can leave a cut in your skin that could need stitching too if they got you really good in a tail whip. Iguanas are definately not the pet for everyone !
Here's a shot of what too hot of a heating element can do for a snake...
