I recommend " The World of Magical Pets " to you. The male protagonist also has a magical pet to follow him. He mainly tames all kinds of magical pets and spiritual beasts, masters all kinds of strange magic skills, and travels all the way to the world. Although I'm not sure if it's a fox or a cat, there are all kinds of magical pets to choose from. It should be able to meet your needs. I hope you like my recommendation.😗
