The story is presented as a first-person narrative using an unreliable narrator. He is a condemned man at the outset of the story. The narrator tells us that from an early age he has loved animals. He and his wife have many pets, including a large, beautiful black cat (as described by the narrator) named Pluto. This cat is especially fond of the narrator and vice versa. Their mutual friendship lasts for several years, until the narrator becomes an alcoholic. One night, after coming home completely intoxicated, he believes the cat to be avoiding him. When he tries to seize it, the panicked cat bites the narrator, and in a fit of rage, he seizes the animal, pulls a pen-knife from his pocket, and deliberately gouges out the cat's eye.
