I love cats and cute illustrations so I loved this book. Even if you don't like cats, I still recomend. So, Katie wants to go to summer camp with her friends, but she doesn't have enough money. When her friends mom offers to pay, Katie refuses, she wants to earn the money all by herself. Katie starts advertising her new business, doing chores for the others that live in her apartement. Soon enough, Katie finds out she doesn't enjoy doing the chores at all. Meanwhile her best friend is sending her many letters about camp, and how much she wishes Katie was there. Then Katie gets a job catsitting for 217 cats!!!! And they are no ordanairy cats, they know all sorts of things that cats shouldn't!!! But soon she starts recieving less and less letters from her best friend, and starts realizing that the lady she catsits for is always out at the time a local villian is commiting crimes. What should Katie do? Good thing she has 217 intelligent cats to help her out!
