I had 2 iguanas as one time. The male rarely let me interact with him, he tolerated me in order to be fed. The female however would often come to the door of the vivarium to be let out so she could climb up my arm and perch on my shoulder for hours.
I had a chameleon a few years ago that enjoyed human contact. She spent as much time curled up behind my ear when she was little as she spent in her vivarium.
I doubt it was love but there was definitely some kind of affection.
Thanks for making me ponder this.
Yeah from what I read it seemed iguanas are thought to show more affection and have preferences over people versus say a snake who seem not very likely to show actual affection. Sometimes the cuddling is also for warmth. It is definitely interested to ponder and got me kind of wanting an iguana to be honest.
