On CBS, the part where a bullet passes out through Sylvester's tail as he tries to plug it with his finger (along with Porky commenting "Mice") was deleted
On Nickelodeon, the syndicated "Merrie Melodies" Show, and Pre-2002 Cartoon Network (which aired this short uncut after said date), the part where Sylvester cuts a noose that a team of night creatures lower on Porky, and Porky accuses Sylvester of attempted murder, was removed.
Additionally, The Merrie Melodies Show removed the part where Sylvester places a noose around his neck to demonstrate to Porky what would have happened to the latter had the former not saved him, while Cartoon Network and Nickelodeon removed the scene immediately after this where Sylvester fights a rifle-mouthed moose head.
