They say that if a person has a pet cat and dies

[IChing]

if the person's body is not found fairly soon after death, the cat, having not been fed, will become ravenously hungry and eat the dead person's face off — JUST the face!

Is this true? My cat often looks me in the face. I used to think he was just being friendly. Now I know he's just sizing me up, like a chef at a butcher shop, waiting for "the big day". Since hearing this rumor, every time my cat licks his chops it gives me the willies!
