Neko no Ongaeshi

Both MC are spirited away into the cat world were they are forced to fight to become humans again 

The film "Neko no Ongaeshi" by Studio Ghibli is a very good recommendation for the anime "A Whisker Away". The stories have many parallels and for those who may not know Studio Ghibli, this is an opportunity to take a look at one of the studio's many wonderful animated films. In both films, the main character transforms into a cat. Even though the reasons for the transformation are different, both main characters go to the realm of cats as a parallel world to face the challenges of their respective magical adventures. There are almost 20 years between the two anime, but I am sure you will be impressed by the visual design of the Studio Ghibli production. Both films were made to very high production standards. They each enchant with great stories, impressive art and animation as well as beautiful music and fitting dubbing. As always, thanks for reading and enjoy watching.  read more 

Both stories involve humans getting involved in the world of cats in unexpected ways, including the main character turning into a cat and then having to explore the world of cats in an effort to return to their life as a human. 

Both movies have a female protagonist who got spirited away into a world of cats, transformed into a cat, and must find the way to turn herself back to a human. If you're a cat lover and like one of these movie, give the other one a try! 

A Whisker Away and The Cat Returns are two beautifully animated movies about a girl who becomes a cat, though each movie have their own separate reasons for why it happens. The girl later ends up in a parallel world where cats thrive. A Whisker Away is more of a character drama than the kind of funny and magical adventure The Cat Returns is, but if you love cats and loved one of these movies, you are sure to enjoy the other. 

The Cat Returns/Neko no Ongaeshi is a nice film by studio ghibli. (Its a spinoff from 'Whisper of the heart'. So you can watch it first. It's not necessary tho.) In both Neko no Ongaeshi and A Whisper Away, the MC turns into a cat and wants to stay like that in the beginning but then later realizes that they were better off in the human form.  

They both... - the plot of a human turning into a cat and then finding a way to undo it - have to head to another world where cat people reside - have a female lead which in both could be described as outgoing,sporty, positive ect - an unexplained fantasy,child like wonder atmosphere  

Both Female Leads get unwittingly stuck in cat form, and have to turn back before the transformation becomes permanent. "A Whisker Away" is heavily focused on a Romantic Slice of Life being forcefully nudged by the supernatural. Whereas "The Cat Returns" more forcefully sucks you into on a thrilling adventure within the supernatural world. Anyone who has seen one and watches the other will immediately be able to see the parallels. 

Both movies have cat transformation, different realms/worlds, some sort of weird love problem and both are beautiful stories.  

If you watch whisper of the heart before the cat returns this cat character will make more sense and it will give more depth to the movie, the cat returns. 

Letting aside the fact that both of this amazing movies are Studio Ghibli's production the storyline of each of them is simply splendid!The animation and soundtrack is beyond comperable and i'm not sure if i can find the right words to describe this amazingness!You ought to watch them!I hope you enjoy! The Cat Returns features two characters from "Whisper of the Heart" 1.Muta (the cat from "Whisper") & 2.Baron (the cat statue from "Whisper") ;) 

Neko no Ongaeshi/The Cat Returns is a spinoff from Mimi wo Sumaseba. The Cat Returns is like the journey of Baron with a Girl who becomes a cat. 

The cat in this movie is the same cat in Neko no Ongaeshi, this movie also makes a reference to the movie Kurenai no Buta because there's something written in a clock that appers during the movie (they found this clock in a destroyed castle). 

Both are about oridnary human children who get transported to a world full of human-like cats. 

Children forcibly get taken to a Cat Kingdom, transform into cats, and need to finish their business there before the next day. Also, the MC in both has a relationship with a member of the cat royalty. 

Both are Ghibli anime focusing on a young female heroine who ends up in a magical world, from where she tries to escape. Both anime have great art and animation, and evoke similar feelings from the watchers. 

Studio ghibli flavour 

In both, main character can talk to cats and is somehow "cursed" to be changed into one if he/she won´t do something against it. The Cat Returns is more adventure while Nyan Koi is more comedy. 

'The Cat Returns' is basically a remake, the plot is very similar, as they are both about a human character who becomes royalty while an elegant swordsman who happens to be a cat who stands on two legs helps them througout the story, and the climax is basically the exact same: a race to the top of a giant tower against the main villain so that the main character can defeat the villain. The villain in both movies also happen to use a magical artifact which gives them all their power; when the artifact is destroyed, the villain becomes powerless.  

Both of these movies are made by Ghibli, has a young female protagonist and a fantasy world. It's an perfect movies for children, but as an adult you can also find way more in those two than just an generic children animation. 

Both have other-worldly aspects with a sense of adventure featuring anthropomorphic cats.  

Both are Ghibli anime focusing on a young female heroine who enter a magical world. They both have romantic elements. Also, both anime have great art and animation, and evoke similar feelings from the watchers.
