This mini-expansion contains 8 identical cat meeples, each player gets 2 at the start of the game.
During the Bastet action, instead of gaining a scribe, players can place a cat on top of a house placed by an opponent - on Osiris, Hathor, or if you're playing with the expansion, Seth.
The space is resolved as if a house was just built. The owner of the house can choose between gaining 2 happiness or a random Blessing.
Cats don't count as houses during scoring, each house can only have one cat on it, and you cannot place a cat on your own house. Botankhamun never places a cat, if you place a cat Botankhamun always chooses 2 happiness, and when playing with the mini-expansion Botankhamun starts with 4VP extra.
The promo pack was available during Turczi Junior Promo Pack gamefound campaign.
