The Cat in the Hat by Dr. Seuss

Two children stuck indoors on a rainy day are visited by the mischievous Cat in the Hat, who turns their quiet afternoon into wild chaos. Though warned by their goldfish, they get caught up in his antics—until the Cat makes a mess too big to ignore. At the end, he cleans everything up, leaving the children to decide if they should tell their mother. It’s a fun, rhythmic story with themes of responsibility, imagination, and choice.
