Tonight's episode was in Tennessee, from about 1996, and the hilarious hairstyles alone made it worth watching.
There was a callout to a "stolen animal" call, and 2 police cars show up at a trailer park to find Male 1 (thoroughly inebriated) accusing Male 2 of stealing his cat. They're the same breed, but the markings are clearly different. There is a definitive answer, though.
Policeman 1 & 2 talk to them:
M1: M2 is holdin' mah cat hostage!
M2: this cat is female.
P1: sir, is your cat male?
M1: nossir, he's bin noodered.
P1: *sigh* but it's a male?
M1: 's name's Buddy Holly! Wouldn't'a called him that f' four years 'f 't was no girl!
P2: OK, that cat? (points to M2's trailer) is a female.
-- pause --
M1, slyly: how long's he had that cat?
P1: not long enough to get it a sex change op. G'night, sir.
Made me laugh.
