I've been trying to search online for a solid answer to my question but figured it might be best answered here. I have a 3 year old iguana who unfortunately is one of the many stubborn ones out there. Even though I take him out of his cage every single morning, he still strongly resists. He is ok when I hold him, let's me pet him, etc but if given the chance he would much rather scurry away than be held. When he becomes aggressive, I have made sure to do as many things as I can to show that I am dominant over him, such as carrying him at waist or chest level instead of on my shoulders or head, and holding him firmly when he struggles or tries to escape, even carefully using my fingers to gently close his mouth if he ever opens it at me. He has recently become very territorial and aggressive (probably breeding season) and I am wondering if I should lower his highest basking spot to below eye level with me. Right now his basking spot is higher than my head in my bedroom at just about 6 feet. I've read conflicting things where some people are saying that their cage should be their territory and that they should be higher than you in order to not stress them out, while others are saying that the iguana should never be higher than you even in the cage but should still be allowed adequate room to climb if desired. I am accepting of the fact that he may never become fully tame or accept me as his owner, but I want to do as many things as possible to have a friendly and tame iguana. What should I do about his basking height and is there anything else that I missing that I should be doing in order to help him become more tame and less aggressive?
