I used to have a Nile Monitor. They are a blast too. My guy would get thrown in the bath tub when i came home from work and i would turn on the heat lamp in the bathroom. He loved it. I would also let him roam the room. He HATED a buddy of mine. Not sure why but he took a shot at him once with his tail and missed but put a a huge dent in the sheet rock wall. I had him since he was a hatchling and when i finally rehomed him, he was around 5 feet. I actually miss him as he was such a laid back guy for me.
