HELP! My cat is VERY aggressive and bites all the time. What can I do?

1. Are you sure he's neutered?? 2. He might be bi-polar. I am serious, he might have mental/abuse issues. Can you get him checked out. 3. Can you get him to an obedience class, or look up Barbara Wodehouse's methods of teaching discipline to dogs in the 90s, it might work on cats. 4. If you got him a cat harness and taught him to walk calmly and methodically outside, it might help his disposition, he could learn to train his thoughts not to be so impulsive, ie, walk him past birds and squirrels after a while and see if he can teach himeself not to attack them. 5. Does he want a girl kitty? 6. Take him on a play date with other cats and let him run around with them to get the agression out before you take him home to feed him and pat him. Hope this helps.
