according to Wikipedia
The story is of a girl named Haru, a quiet and shy high school student who has a suppressed ability to talk with cats. One day, she saves a dark blue cat from being hit by a truck on a busy road. The cat is Lune, Prince of the Cat Kingdom. As thanks, the cats give Haru gifts of catnip and mice, and she is offered the Prince’s hand in marriage. Her mixed reply is taken as a yes.
This is how it begins before you are taken into the world of The Baron and The Cat Kingdom. Where soon Haru discovers she is slowly transforming into a cat and it is up to The Baron to save her.
Their escape across the maze then up to the tower as the king wants Haru to marry his son at any cost all the while never really listening to his son who really has someone else in mind.
The Cat Returns like all Studio Ghibli films is brilliant and the story take you into a world you would love to visit. Like all of their films.
The film pokes fun at royalty and customs that a lot of us think are silly. If you get a chance you need to check this one out.
…and yes the film has been dubbed into English
