πI recommend the following pet fantasy novels to you: Bloodthirsty Concubine: Cute Beastmaster, Rebirth in Another World: Raising the Strongest Male God, Pet Star Flicker, National Beast Taming: My Pets Can Be Combined, All My Pets Are Gods, God-level Pet Evolution System, All My Pets Are Super Gods, Super God Battle Pet Master, Imperial Pet, Daily Pet Games, Star Domain King of Gods, and Monster Trainer. Their plots revolved around pets, and some even had elements such as contracts and competitions. I hope you like my recommendation.π
