She knows she is in control. She has plotted and won, your sorry ass is hers.
She looks devious than mischievous.
@Sheannutt I bet she is. My cat is devious like that too.
She looks like a bad-ass. Your son should have a beware of cat sign.... LOL
@Sheannutt I'm sure she is a sweetie!
That is a look of intense concentration, better bolt your doors tonight.
