Pettson is an old farmer who lives with his cat Findus in a Swedish farmhouse. Findus wears clothes and acts like a small child, standing on his legs and talking to Pettson. Each story in the Pettson and Findus book series starts from simple everyday events like gardening or fishing and shows the friendship between Pettson and Findus. In one story, Findus disappears and Pettson can't find him alone, so invisible creatures called the Muckles come to help locate Findus. The Pettson and Findus books have been published since 1985, translated into 44 languages, and adapted into animated movies.
