Now this is going to sound weird, but you really need to let cats know that this is unacceptable. I have 7 cats in my house... they never go outside. Nearly all of them will play nip my husband, play rough with him with claws out, etc. NONE of them would think about playing like that with me. As soon as any cat shows a behavior with me like play-biting or claws out, I hiss at them and might thump their nose lightly, letting them know this behavior is unwanted.

It is amazing to see how different the cats are with me vs. how they are with my husband. They come and sit with me and love on me, but never, ever with claws or teeth. Cats do understand hierarchy and I am definitely alpha cat in my house.
