In Cat and Mouse, a game for two players, 16 cards are shuffled and then placed face down on a table as shown below. Cats are pictured on 8 of the cards and mice on the other 8. Both players pick up two cards at each turn, taking care not to show the cards to the other player. If the two cards are a cat and a mouse, the player keeps the cards and scores a point, but does not reveal which was the cat and which was the mouse. If, however, the two cards are both cats or both mice, the player must put the cards back in the same places. My sister and I are currently playing a game, and I am leading by 3 points to 2. The game has progressed so far as follows: [image of table] It is my turn again and I know for certain that the two cards I am going to pick up will be a cat and mouse pair.
