I think he's just having a litte ratty tempter tantrum Frisco used to do that all the time. He wouldn't come near me, and he wouldn't take food, and whenever I stuck my hand in he would stand on his hind legs and puch my hand away with his paws lol. It only took him a while to calm down.

If that's not the case, that would really suck if you had to rebuild his trust....
