The plot (spoiler alert) involves a feral cat that is adopted by the Griffin family, but the cat has less than honorable intentions. Pouncy, as the cat is called, is part of a long-term feline plot to control the human race by spreading a parasite called toxoplasmosis that purportedly affects human behavior. Pouncy sets his sights Meg, the daughter of the family, and starts to turn her into a crazy cat lady.
