I recommend "The Age of Demonic Beasts". This is a fantasy romance novel. The female protagonist, Lu Yan, was pulled into the world of demonic beasts by a stray fat cat. In the end, she fell into the world of beautiful men. However, she was not interested in handsome men. She was only interested in animals. Therefore, all the beautiful men were transformed by her.
