Cat Kingdom

The Cat Kingdom is featured in The Cat Returns.

The Cat Kingdom is a world parallel to the human world, simply inhabited by cats. The Cat King rules the Cat Kingdom. Common cats don't wear clothes, except for noble cats. The cats eat mice and fish. At the castle, the variety of food is much bigger.

In an additional element not included in the film, it is revealed that the Cat Kingdom is where cats go when they can no longer live in the human world, thus implying Yuki is deceased.
