Purrbit

Terra follows the oldest law on Earth: if it lands near you, it belongs to you. Nova follows a different law: if you can reach it in space, it belongs to you. One night, they both noticed the Moon. Terra saw a giant ball hanging above his backyard. Nova saw a giant ball floating beside her spaceship. They jumped for it at exactly the same time. Terra pulled with gravity. Nova pulled with zero gravity. Neither cat would release it, and the Moon has been circling Earth ever since. Purrbit is the universe's longest game of keep-away: one Moon, two stubborn cats and absolutely no plan for what happens when somebody finally catches it.
