Heathcliff and the Catillac Cats - Season 1 Episode 65

Heathcliff suffers a nasty bang on the head, which renders the "Devil Cat" side of his personality stunned and permits the "Angel Cat" side to take over. Suddenly Heathcliff is good as gold and begins performing numerous acts of kindness toward Spike. Spike is confused, but certainly willing to take advantage of the situation. He even puts on a show for the other animals to demonstrate his new ability to make Heathcliff do his bidding. However, when the "Devil Cat" recovers, Heathcliff puts Spike back in his place posthaste.
