This is why it's important kittens stay with mum and their siblings longer than 6 weeks. The kittens play fight each other and take out their energy fight one another instead of you. They also learn how far to go as it when they've been to rough etc. I clip all of my cats claws quite often and thus they are not sharp. Aside from a scratch poll and clipping I wouldn't know. If she hurts you just put her on the floor and stop the game.
