Rat Life and Diet in North America -- Film Description:
"The 'rats' in the film, who are actually gerbils [...] escape from their cage and evade those who held them prisoners, the cats. On their way they have many adventures, including breaking into the house of a millionaire and stuffing themselves with rich foods from his table. They arrive in Canada in time for cherry season and have a cherry festival and celebrate with a flower ceremony as well. There they will live in peace and grow their own organic vegetables."
