Lucy: "Kiss my grits."
ETA: Lest you find yourself worrying about Lucy:
1) She outweighs Frisky by a good 5 lbs or so;
2) Her growls are about an octave lower; and,
3) She is a talented boxer with a penchant for hitting Frisky with a quick two-paw right-left smack to the face.
Believe you me, the smart money is on the cat.
