A tale of two kitties (1942)

Two alley cats, Babbitt and Catsello, decide to make a meal out of Orson as he sleeps in his nest atop a telephone pole. The gullible (and loud) Catsello is repeatedly gulled into trying to "get the bird," earning a variety of thrashings from the casually murderous little canary. Catsello finally resorts to an air strike (with a pair of wooden boards for wings), but it's wartime, and Orson has the cat blasted out of the sky by anti-aircraft guns.
