The protagonist of this story has a black cat named Pluto as his favourite pet. He gets into the habit of drinking, and one night, when he is drunk, he attacks the animal, cuts one of its eyes out and finally hangs it. That very night his family house burns down and the image of a gigantic cat appears on the only standing wall of his burnt house. The ghost of Pluto haunts him for several months.
One night, another cat appears; it is black with a white spot on its fur. He and his wife get very fond of their new pet, but one night, while drunk, he tries to kill the animal because it resembles Pluto too much and he feels guilty. His wife tries to protect the animal and he murders her with an axe.
He buries his wife's body behind the wall and the cat mysteriously disappears. When the police, attracted by a lament behind the wall, breaks it down, they discover the missing cat over the woman's corpse.
