Figaro and Frankie (1947)

Figaro the kitten is annoyed by the chirpings of Frankie the canary. He knocks over Frankie's cage; Minnie thinks he's eaten Frankie and throws him out. But Frankie was only hiding, and flies out the window straight into the clutches of Butch the bulldog. Figaro wrestles with his conscience (literally), but ultimately saves Frankie and gets thanks from Minnie.
