I think you will find that Mishi is the dominant cat. The pic where he is looking down at her with ears at airplane position is a classic dominant pose. Then in the next it looks as if he is biting her on the back....but he is definately forcing Mitzi into a submissive position. This is not bad at all if Mitzi is agreeing to it which by the last pic it certainly looks like that is the case. Your household will be much happier and calmer when they determine and agree upon their respective positions.
