The Discontented Canary is a 1934 Metro-Goldwyn-Mayer Happy Harmonies short directed by Rudolf Ising.
Then, their owner arrives, but she accidentally leaves the cage open.
Suddenly, a lightning bolt strikes the cat's tail and he runs away screaming in agony.
Realizing the outside world isn't as safe as his cage, the canary flies back home and sings as the cartoon ends.
