The objective of this children's game of luck is to have the most cards at the time that a player receives his ninth mouse chip. Players discard cards until a mouse card is discarded. The mouse card has one to three paw prints on it and the following player discards that many cards. If one of them is a cat card then the player who played the cat card earns a mouse chip and puts the entire discard pile at the bottom of his card pile otherwise the player who played the mouse card gets the discard pile (but not a mouse chip). - BoardGameGeek
