The Feudin' Hillbillies is a 1948 Mighty Mouse cartoon.
It's the Catfields and the McCoys, Mighty Mouse style, with hillbilly mice vs. hillbilly cats. The mice and the cats are peaceful until the mice strike up a string band. The cat family throws a fishhook across the ravine and tries to steal the cheese from the mice. That's when the feuding starts all over again. There are whiskey stills and gun battles, with the hillbilly cats fighting Mighty Mouse.
This Cartoon is a Parody of the Real Llife Hatfields and McCoys Feud
