I posted the beginning of the month about my sweet iguana going psycho. To make a long story short...she was spayed in February, and shortly after she began acting like a male iguana during breeding season. She is 4 years old and almost never showed any aggression. I decided to call the vet yesterday since she started to show aggression towards my parents now, and was afraid she was going to hurt herself by throwing herself head first at the door of her cage trying to bite me. The vet did some research and thinks it may be from too much testosterone and something with her adrenals glands giving off too much testosterone. She said to try giving Iggy 1mg of Melatonin at night for a week and see how it goes. Has anyone ever tried this or know how it will effect her?
