My cat Scooter is a 3 yr old (approx. I don't know for sure) fixed male who acts like he is a kitten on speed. He tears around the house like someone put a hot poker up his rear. Up, down, left, right, nonstop. He rarely sleeps, but seems healthy. He lets you pet him for a few seconds then bites and/or scratches you (in a playful way). In the middle of the night he will attack your toes while you are in bed. He is possesed and has bitten a few people for no apparent reason. He is cute and can be sweet, but his behavior is driving us nuts. We've tried using loud noises, a water bottle, etc. for behavior modification, but to no avail. Help, please!
