It's the world of cats and dogs. Blackie, a little black kitten (who lost his mittens), dreams that he runs off to join a school for criminals. Tiring of "sissy stuff," he gets his wish when he teams up with Fagin and his school for young crooks. Blackie gets mixed up with some bad cats. There's a shootout with police dogs. The scenario is a perfect excuse for the "Three Little Kittens" song.
- In the reissue, the WB shield does not come out fully, resulting in the 1943-1947 WB shield being shown instead of the 1947-53 WB one. A similar error occurred in the reissue of "Toy Trouble".
