Speaking of Iguanas, I rescued one from near death many decades ago and he was the smartest lizard I have ever known. For starters, even though he was a full grown adult, I was able to potty train him in just one session. He had to go rather badly, and was climbing the walls of his tank so I took him out, guided him into the bathroom onto the newspaper I had laid down, and gently held him there until he went. That was all it took, after that, I never had to worry because when he needed to go, he'd go to the bathroom...to go to the bathroom. Amazing creature. He *loved* green peas, so much so that I'd have to bury them under the rest of his vegetables otherwise he'd eat only those. I bough so many different vegetables at the local Kroger that they all thought I was a vegetarian. Only thing Big Ig (yes, that was his name, I am bad with names) didn't like, was bananas, which is something that surprised me, as everything I had read said they loved them.
