You didn't do anything wrong. I am going through the exact same thing with mine right now. Although my situation is a bit different it has a lot of similarities. Mine is just still hungry. He knows he gets fed at night so at night if I get close to the hide he pops out and follows me. He's ready to move up on prey size. Yours probably smelled rat and knew it was supposed to eat. That's probably all and it'll probably calm down in a day or two.
