Pettson och Findus â Kattonauten is a Swedish children's film from 2000, based on the books Pettson and Findus by Sven Nordqvist.
The cat Findus decides he wants to write a letter to the King, in an attempt to convince Pettson, that kittens don't have to clean up. While Findus waits for a response, he and the old man are visited by tigers, moose and an occasional forgotten relative.
