kitty cat sleeping

You know some cats don't like to be held? some love to, and so on. My cats refuse to be held (they will scratch you to death if you try to hold them!) but they don't have any problem coming up to you and laying top and start purring. Its a rarity that my cats will actually sit my laps or wherever for a long time, so when ever they do I don't want to move. Even if its very uncomfortable!
