The Tom and Jerry Show III (33)

Rick and Ginger wake up late and, in their hurry, they accidentally put dog food in Tom's bowl and cat food in Spike's. This causes Spike to behave like a cat and Tom to act like a dog. Although they're confused at first, they soon eat other types of food and discover how it makes them act.
