Steve Jackson Games created a popular card game called Munchkin where you use cards to fight each other. The game proved surprisingly popular that the company quickly developed additional expansion packs for the game including vampires, zombies, and science fiction.
Now Steve Jackson Games offers an expansion kit called Munchkin Kittens. The idea is to add cat-related playing cards to any Munchkin game. Now if you like both cats and the Munchkin card game, you can indulge in both with the Munchkin Kittens card game expansion kit.
