My 8 month old kitten, Malachi, came to us from an adoption agency a little aggressive. He tends to bite and claw when playing or excited and we've tried to eliminate this behaviour by scruffing him, spraying him with a water bottle, or shaking a can full of dried beans. However, he has not stopped this behavior or other things we don't want him to do (being on the kitchen counter, running across our beds while we're asleep). Instead, he's learned he can avoid the punishment by running away. He'll bite us and then run off before we can grab him, or run across the bed and then hide under it. Is this a phase or have we come about disciplining him in the wrong way?
