Photo Spotlight (Conflicting Emotions Cat)

    I have a cat named Jack who I believe is very bipolar. Often called by me "the assassin cat," Jack spends his days laying on the back of the couch by the window, or on the railing of the stairs, just staring straight forward not blinking for hours, and only moving if he needs to eat or use the facilities. Even if you go scratch his favorite spot, on the very top of his head, he wont blink, move or anything. Until suddenly, his tail will start to wag, meaning he's angry, and he will bite onto your hand lightly as if saying "go away and leave me alone." But sometimes he will be in a good mood and when the conditions are right, he will walk at his normal, very slow, pace onto your lap and sleep there until disturbed. He will also usually sleep with me, since for some reason, I am his favorite.
     Jack only has 2 speeds. Snail, and lightning. He either moves very slow, walking right along the wall as if trying to be stealthy, or sprinting as if running from something. He is rather comical to watch as he slowly moves across the floor, watching for the dog or other cats that may bother him. He's quite antisocial with other cats. If they get within ten feet of him he attacks them to get them to go away, paws flying, claws out as he tries to rid his area of the intruding animal. He is definitely a bipolar cat, and this picture of him captures it perfectly.
   The picture was taken in August of 2012, when Jack was in his usual back of the couch post. The lighting on him captures his nice, and dark side. The right side shows his nice side, the dark side shows his aggressive and evil side. It shows his personality perfectly.
