Plot Summary
The nameless protagonist/narrator begins his story by letting the readers know that he was once a nice, average man. He had a pleasant home, was married to a pleasant wife, and had an abiding love for animals. All that was to change, however, when he fell under the influence of demon alcohol. The first symptom of his descent into addiction and eventual madness manifests with his escalating maltreatment of the family pets. The only creature to escape the man's initial wrath is a beloved black cat named Pluto, but one night after a serious bout of heavy drinking, Pluto angers him for some minor infraction, and in a drunken fury, the man seizes the cat, which promptly bites him. The narrator retaliates by cutting out one of the Pluto's eyes.
While the cat's wound eventually heals, the relationship between the man and his pet has been destroyed. Eventually, the narrator, filled with self-loathing, comes to detest the cat as a symbol of his own weakness, and in a moment of further insanity, hangs the poor creature by the neck from a tree beside the house where it's left to perish. Shortly thereafter, the house burns down. While the narrator, his wife, and a servant escape, the only thing left standing is a single blackened interior wall—on which, to his horror, the man sees the image of a cat hanging by a noose around its neck. Thinking to assuage his guilt, the protagonist begins searching out a second black cat to replace Pluto. One night, in a tavern, he eventually finds just such a cat, which accompanies him to the house he now shares with his wife, albeit under greatly reduced circumstances.
Soon enough, the madness—abetted by gin—returns. The narrator begins not only to detest the new cat—which is always underfoot—but to fear it. What remains of his reason keeps him from harming the animal, until the day the man's wife asks him to accompany her on an errand to the cellar. The cat runs ahead, nearly tripping his master on the stairs. The man becomes enraged. He picks up an ax, meaning to murder the animal, but when his wife grabs the handle to stop him, he pivots, killing her with a blow to the head.
Rather than break down with remorse, the man hastily hides his wife's body by walling it up with bricks behind a false facade in the cellar. The cat that's been tormenting him seems to have disappeared. Relieved, he begins to think he's gotten away with his crime and all will finally be well–until the police eventually show up to search the house. They find nothing but as they're headed up the cellar stairs preparing to leave, the narrator stops them, and with false bravado, he boasts how well the house is built, tapping on the wall that's hiding the body of his dead wife. From within comes a sound of unmistakable anguish. Upon hearing the cries, the authorities demolish the false wall, only to find the wife's corpse, and on top of it, the missing cat. "I had walled the monster up within the tomb!" he wails—not realizing that in fact, he and not the cat, is the actual villain of the story.
