Lola, the kneading is a comfort action for her, and really a high compliment to be paid to a human. Even with sharp claws. Karma, my one cat that was abandoned and just wandered over here, is a horrible kneader. We have a heavy towel we use when we see her coming to protect us. Play swatting is Mocha's way of saying you are annoying her, to stop this, you have to be quick and stay out of the way, but blow one gentle puff of air in her face and tell her sharply one time "QUIT!" and she will back off.
