While you can download, play and progress in C.A.T.S. for free, the game offers the option to purchase in-game currency (gems) for real money to speed up some processes. You can buy it in the game itself using a credit card. These purchases are handled entirely by Apple or Google to ensure the maximum transaction security.

Please note that we respect the player's right to choose how they want to play C.A.T.S., and all areas of the game are equally accessible to both paying and non-paying players.
