Maddy Lloyd is a girl with a magic secret. She has three tiny ceramic cats that one at a time comes to life. The pocket cats help Maddy to solve problems. It's when her cousin Chloe moves in the house that Maddy meets Nibs, the second cat. Nibs tells Maddy that there is a problem in the house and she believes that has something to do with Chloe. Maddy's cousin Chloe is in middle school, she is not very friendly to Maddy or anybody and this is because she feels homesick. Thanks to magic powers, Nibs makes Maddy invisible and this helps her to spy on Chloe.
