Synopsis: Publisher's synopsis: "Humans have left the Earth, and dogs rule. Kipper is an oppressed tabby cat who dreams of a better place where cats are free to run their own lives. When Kipper discovers a secret that might lead her to such a paradise, along with the secret comes trouble - first, Kipper's sister disappears, and, then, she's attacked by a dog goon herself. Kipper's escape takes her on a mad dash to Ecuador and the space elevator, where she catches a ride up to the otter-designed space station. Once in 'otter space', Kipper must navigate an uncomfortably watery world to find out what happened to her sister and whether there really is a cat paradise."
