The Cat Returns (2002) IMDb
An ordinary girl in modern Japan is involuntarily initiated into the secret life of cats. Muta/Moon and the Baron from Whisper of the Heart (1995) accompany her to their hidden kingdom.
Light, mainstream comic fantasy. Directed by Morita Hiroyuki. It’s a shallow, less serious clone of Spirited Away (2001) with poorly recycled characters and ineffective anthropomorphism. A definite low for Ghibli.
