Give your cats a more stylish ball to play with.

This is a paid DLC that expands the soccer ball play.
In the free version you get just one simple ball, but installing this DLC unlocks the following two things.

9 Ball Designs

From the classic soccer ball and beyond, pick whichever ball you like from nine designs. Switch them to suit your mood or the look of your desktop.

Show Up to Two Balls at Once

You can now place two balls on screen at the same time. With more balls around, your cats get even livelier.
Two cats might each chase their own ball, or both pile onto a single one — a wonderfully lively scene.

As always, the balls move with natural rolling, bouncing, and spinning driven by the physics engine, and the cats chase after them on their own and roll them around with their bodies. You can also grab and throw them with your mouse.

* The base app “Sill Cats” is required. You can switch the type and number of balls shown at any time from the settings screen.
