A cat tries to catch a canary, but he is stopped by the old woman and she threatens to throw him out in the rain. So the cat tries to pull some devious tricks to get the bird, but he keeps getting interrupted by the canary's whistle. The canary at one point even gets the cat to whistle by showing him a picture of a pretty girl. The canary even taunts the cat while flying to & from his cage; but the cat was waiting for him and the canary escapes. So in desperation, the cat put ear muffs on old woman while she was sleeping. The canary tries whistling but to no avail, so then he makes all sorts of noises before hitting the cat with a wall ironing board, allowing the canary to remove the earmuffs from old woman. Finally, the cat has had enough, so he let himself out in the rain. The canary was victorious, but his victory wouldn't last as old woman woke up and is somehow angry. So a frightened canary flew out in the rain too. Left all alone in a barrel with the cat, the canary ended the cartoon by asking the audience if they were interested in a homeless cat & canary.
