My cuban(I will have a name for him soon)iggy bit my cat on the leg. I think he was just tasting him. Anyway usually when the iguana walks he goes right for the cats and makes them move out of the way. The cats follow him around, and the kitten tries to chase him. The iguana was under his enclosure exploring and the cats were sitting with me on the floor. I think he got jealous and walked up to out big cat like normal and licked him on the leg. The cat flinched a little and looked at him. Then out of nowhere the iggy bit the cats leg. He had his whole leg in his mouth. He didn't bit hard, just enough to make the cat jump and holler. Then the iggy sat down with me. He looked up and had this look on his face like ..."what did I do?"...with a mouthful of cat hair. He isn't aggressive with the cats at all, I think he's just letting them know he's in charge. The cats haven't really figured him out yet. I just thought everyone would enjoy that story. I am always right there when I have him out so he or the cats aren't in any real danger from each other.
