There are a lot of things you need to do before you just let your iguana roam and live outside of an enclosure. Remember it needs UVB light and a place to bask. I don't think you want your room 85-95 degrees it would be pretty unbearable for you. You have to make your room iguana proof. Iguanas can fit into really small openings and under doors and other places you wouldn't think they could fit. They are great escape artists. Even if they don't fit they will still try and probably get hurt. Also make sure that nothing can fall on it. Or when it climbs on stuff make sure it is stable and not going to fall over. I don't know how big your ig is, but it makes a difference in some of the things you need to do and watch out for. I would like to have my igs be free roamers, but they need to get bigger first. It would take a lot for me to ig proof my house. I will always have an enclosure for them too. Good luck and I hope your iggy becomes friendly. I hane feed my igs all the time. I think they prefer that.
