A kitten wanders in to Betty Boop’s house and becomes sick after eating a box of candy. Betty sends Pudgy to the drugstore for catnip while she attempts to nurse the kitten back to health. Pudgy spills some of the catnip on the way home and the kitten’s mother catches its scent. She chases Pudgy and the catnip back to Betty’s house and is reunited with her kitten.
