Gösta Knutsson

Pelle is a cat who was born without a proper tail. He is taken care of by a family living in Uppsala. Without a tail, he becomes the talk of the town among the other cats, and especially Maans, who teases him cruelly. Maans' rough and silly courting of Maja Graeddnos does not impress her, since she becomes interested in the kind and gentle Pelle. But Maans won't give up that easy... (imdb)

Pelle is a cat who was born without a proper tail. He compensates this by studying hard and, much to the dismay of his archrival Måns, receives a fancy degree very few cats in Sweden have obtained. Some time later he is visited by his relative Pelle Swanson who invites him over to visit his new home country America. There everything is bigger, even the rats are much fatter. Everything seems possible in America, even the prospect of finally having a proper tail and a sweetheart to call one's own. (imdb)

The film's characters are based on Gösta Knutsson's books about Pelle Svanslös
