I don't know, BenMax. This is my first reptile ever. My nephew has a bunch. He is certainly bonded to them, if not the other way around! lol! It's definitely not like a dog, cat or other mammal, but there is a certain amount of recognition there, I think. His iguana certainly seems to enjoy his company over other people's.
True, Macomom. Don't they have sweet little smiles?
