The Last Hungry Cat (1961) *****

A great parody of Alfred Hitchcock's films with Sylvester haunted by his guilty conscience for supposedly devouring poor and hopeless Tweety. A superbly crafted masterpiece with a carefully maintained somber mood and some hilarious touches of black humor (including "gas chamber music"). Along with 1951's "Canned Feud", this is Friz Freleng's finest achievement.
