Written in 1920, "The Cats of Ulthar" is H. P. Lovecraft's whimsical yet darkly supernatural tale set in the dreamland city of Ulthar. When a young wanderer's kitten is killed by a cruel elderly couple, mysterious forces are set in motion that lead to a shocking act of vengeance. The story exemplifies Lovecraft's ability to blend folk-tale simplicity with cosmic strangeness, exploring themes of justice, the unknowable nature of cats, and the thin boundary between the mundane and the supernatural.
