Anglais - Fort: Cats & Dogs Expansion adds two modules to the Fort base game: dogs and cats. You can use one or both, as desired. Dogs are loyal. If you play one, it will (usually) go stay in your doghouse, but they're fussy, so you can play a dog only if you meet its needs. Neglect a dog, and it'll wander off. At game end, whoever has the most dogs in their doghouse scores seven points!
