We put up with a lot of cheeky fuckery from our feline overlords, but there are specific things they do to show you that they love you.
DH's Overlord punches him in the face when he is hungry at 5am. If DH is ill, the fluffy idiot will sit on his chest in an attempt to make him feel better. He is a bloody big Maine Coon, so DH simultaneously suffocates and gets too hot.
Mine is a dumb as a half brick and attacks my work screen to protect me, when I am on a conference call to a client. It's become a rite of passage now.
What's yours?
