At the start of each episode, you begin with Kitty Treat tokens equal to the number on your character sheet. (For new kitties, this is 2.) These treats are a way to change the story of the game to the kitty's favor. They don't roll over from the previous episode. Kitty treats can be used to re-roll one or more dice in your dice pool, to avoid an injury, to use a bonus feature for one of your Magical Powers, or to add something to the story beyond the kitty's control.
You can earn more Kitty Treats during play by using your kitty's Flaw. When a kitty's Flaw makes the game more interesting or fun, or makes it harder for the kitties to achieve their goal, the GM might give you another Kitty Treat.
