Cats love boxes! Launch cats of different sizes into the box. If two cats of the same size touch each other, they merge into one larger cat. If the cat falls outside the box, the game ends.height/width at which your game is optimized at. Please note that the size will be available in the catalog for publishers to see. In the game, you can also use the mouse to drive any cat out of the box. Also, from time to time you can catch mice that give this opportunity. Try to unlock all the cats.
