The narrator has always loved animals ever since he was young. Though, his favorite animal was his black cat named Pluto. He was married young, and he kept Pluto. Pluto has always followed him around.
When the narrator started to drink alcohol, his temper started to get worse and his anger grew. He began hurting his pets, but tried to restrain himself from hurting Pluto. Eventually, he cut out Pluto's eye because he was avoiding him. He felt bad so he hung Pluto on a tree to put him out of his misery.
One night, the narrator's house burned down. After the fire, only one wall survived. The wall that had survived, had an imprint of a cat on it. The narrator thought that the neighbor cut Pluto from the tree and threw him into the fire. After he was thrown into the fire, Pluto was burnt into the wall.
When the narrator was at the bar, he found a cat that looked exactly like Pluto. The only difference between the two cats was that the new cat had a white mark on its chest. The cat followed the narrator home, and he began to like the cat. Shortly after, the narrator started disliking the cat because it kept following him.
The narrator was walking down the stairs, but the cat tripped him. He was mad, and the narrator grabbed the axe and was about to kill the cat. His wife stopped him before he could kill the cat, but in his rage, he killed his wife. He had to hide the body, so he decided to wall it up in the cellar. He didn't feel guilty, but instead he wanted to look for the cat, because he couldn't find it.
The police came to the narrator's house to see if the wife was there. He invited them in thinking they wouldn't find the body. He was sure the police had searched everywhere, but when he tapped on the brick wall, there were cries from the cat. The police took down the wall, and found the body of his wife and the cat inside. They arrested him right after.
