I had a calico that was 7 lbs of attitude. My boy Madmardigan is her son and she couldn't stand him right up to the day she died. Anytime he came near her she'd thump him a good one. My ex called her "The Paw of Death" because she'd stretch out on the back of the chair and flex her claws while staring you right in the eye like she was plotting your demise. All of the female cats I've had have had this attitude, though she was the worst. From now on I'll have boy cats, TYVM.
