Tomcat Anton lives with his clever roommate, cat Hilde, on the edge of the forest in Herzhausen. One day, when Hilde tells him about a mysterious animal with a bushy tail, Anton's curiosity is piqued - and an exciting adventure begins. Together with Hilde, he explores the nearby forest. They encounter wild boars, observe a woodpecker, and meet a little mouse named Lilli, who soon becomes a loyal companion. With keen eyes and growing knowledge, they get to know the animals of the forest - and discover how important friendship, courage, and consideration are. From this special bond, an idea emerges: Anton, Hilde, and Lilli together establish the Club of Animal and Forest Guardians - to preserve all that they love. A lovingly told adventure for both reading aloud and self-reading, filled with wonder in nature, discovery, and togetherness - featuring coloring pages, animal profiles, and lots of heart for young and old readers alike.
