He is about 6 months old. I only let him out today on a plant that was by his cage, right away he crawled over to the window and was trying to climb the glass. He would never be out unless I was there to watch him due to 3 cats and two large dogs that live here as well. I would hate for anything to happen to him even if they were only checking him out, who knows what could happen. So he wouldn't even be out for maybe an hour or so at a time.
