Oh, and tip for when you do start handling, don't put him back in his tub if he strikes at you. I wouldn't keep him out so long that he is beside himself with stress, but if you put them back as soon as they strike, you can classically condition them to think they will get their way if they are aggressive. If he strikes, hold him gently for a few more minutes and then return him to his tub by letting him crawl into it on his own. Move very slowly and gently.
