Neko to Ryuu

The story follows a fire-breathing, human-hating dragon raised by a mother cat in a forest. The dragon, known affectionately as "Uncle Wing," watches over the many curious cats — such as one that goes on an adventure with a human prince, and another that lives in the city and people-watches as a hobby — and gradually warms up to humans along the way.
