Heathcliff and the Catillac Cats (1984)

S1E65 Spike's Slave

After a hard knock to the head, Heathcliff's mischievous "Devil Cat" persona is temporarily subdued, allowing his gentle "Angel Cat" side to emerge. In this unexpected shift, Heathcliff becomes exceptionally kind, showering acts of goodwill on Spike. Though puzzled, Spike eagerly seizes the opportunity to exploit this change. He even stages a performance for the other animals to showcase his newfound power over Heathcliff. However, once the "Devil Cat" regains his strength, Heathcliff swiftly reasserts himself, reminding Spike of his rightful place.
