Thanks everyone

I think Emma would stop smacking him if he didn't run away, she definatly does it more often since he started running.

I don't think it's play, sometimes she'll hear him walking towards my room and she'll run out and hiss and smack at him before he can even get to the door-way

I always pick her up and take her away when she does this, is this going to help, or should I do something different?
