Cats are supposed to be staying at home and chasing birds, at least that's what Katy has always been told. Katy knows that she loves singing though and keeps practicing even when all the other animals tease her. She knows that one day she will finally get the chance to live out her dream and perform on Broadway. One day, Katy is practicing singing on a tree in her backyard when she has a fight with a squirrel named Gerry and ends up falling out of the tree! She falls into the street and starts running to avoid traffic. She keeps running until reaches the big city where she meets a cat named Weasel. Katy quickly becomes friends with Weasel, and he teaches her the ways of the city such as how to stay safe and find food! The big city isn't everything Katy hoped it would be, and she starts to miss everything about her home, even Gerry! After a few days in the city, Katy wakes up from a nap and hears someone singing. She follows the sound of the voice until she reaches a stage that she realizes is Broadway. Is this finally Katy's chance to make her dreams come true and perform on Broadway?
