Q: What if there's a planet where the highly intelligent beings are cats and dogs, and humans are pets? A: Is this heaven! After Sophia died and was reincarnated, she traveled to an extraterrestrial planet where cats and dogs dominated, and she started living like a pampered pet in paradise without having to work or earn money, surrounded by cats and dogs. But there was one thing: she was the pet. Sophia (with a sparkle in her eyes): These cats and dogs are so darn cute! Beautiful Ragdoll cats! Lovely Doberman pinschers! Heaven! Cats and dogs (with a sparkle in their eyes): This human cub is so adorable! Soft face! Smooth skin! Treasure!
