The cat leaders who live in the city decided to use Cat Racing to settle the endless fights on territory, and so they have come to the forest. The mouse henchmen heard rumors of the race, and so they have schemed to use the fights among the cat fellows, who have always tormented them, to make money. Then……the usually quiet forest stadium, where cats’ and mice’s hot battles and gambles are unfolded, becomes a Cat Stadium. You are a mice boss. Let’s lead the henchmen wisely to influence the cats as you please, and make magnificent amount of money.
