He will hit me on the head to wake me up to scratch his head and chin, then suddenly, without warning, attack and bite when he wants me to stop. He will not let anyone except me, my mom or dad pet him, and even then he attacks without warning. In fact, anything can trigger an attack. When my dad was unable to get a window open for him to sit in, he took a swing at the poor slave. He once shredded an entire bulk package of paper towels, every single roll almost down to the cardboard middle. He tore up a vinyl closet and destroyed a couch. I admit, it took a while to establish who the boss is, but after he really put his paw down one day, I try not to do anything to aggravate him.
