Iguanas are notorious for taking a dislike to some people, and can do so for no apparent (to us anyway) reason at all! Mine had never exhibited any behavior of that type and she had been carried around into flea markets and petstores, being touched and looked at for years. But her first introduction to the new neighbor in our Apt complex resulted in a total freak out! It was all I could do to hang on to her. Who knows what goes on in their scaley little heads at times. Its a difficult choice to have to make and I stand behind Lacey in her decision.
