Tuckered out from a journey across the Wild West, cat brothers Anton and Cecil are ready to head east for home—until a minor stop to change trains in Chicago turns into a major adventure. A bloodhound detective recruits the brothers to help solve a case: puppies are disappearing right off their leashes!

Anton and Cecil's search takes them deep into the heart of the 1893 Chicago World's Fair, where they befriend exotic animals, ride the newly invented Ferris Wheel, and look for clues amid the crowds of fairgoers. Just as they close in on the culprit, Cecil is carried away in a giant flying balloon and Anton is left behind. Can the cat brothers find the puppies and each other in this big, busy city?

Fans of classic animal adventures such as A Cricket in Times Square and Poppy will love Anton and Cecil's world, brimming with action and rich, true-to-life detail.
