Help, we have the worst cat in the world. I want to keep him but if he doesn't start behaving I don't know what else to do but give him up. He knows what the word NO means but he doesn't care. He's a biter, he constantly attacks our other cat and is driving him crazy. We have tried the water bottle, spanking his little butt, yelling at him, time out. You can't catch him when he's doing wrong because the little devil is so quick. Help. On the other hand he can be so loving you would think we had 2 different cats.
