Fort: Cats and Dogs
You've begged and pleaded with your parents and finally... it's time to get a pet! This expansion to Fort adds two modules: Dogs and Cats. You can use one or both.
Dogs are loyal. If you play one, it will (usually) go stay in your doghouse. But they're fussy: you can only play a dog if you meet its needs. Neglect a dog, and it'll wander off. At the end, whoever has the most dogs in their doghouse scores seven points!
Cats are fickle. Their actions happen at specific times, and they move around a lot. Cats will be attracted to a different player if their Yard has cards of specific suits, even if the cats current owner has them too. The more cats you have at the end of the game, though, the more points you score.
