Sill Cats is an always-on desktop app that brings small, animated cats into a computer workspace. They wander across the desktop and window tops, settle down to sleep, and may react when the cursor moves. The appeal is less about pursuing an objective than sharing your screen with pets whose behavior gives the desktop a gently unpredictable presence.
Interaction is simple but varied: a click can catch a cat’s attention, while additional clicks may prompt a response or play. Cats can also bat at the cursor, and their activity shifts with the time of day, with livelier periods around dawn and dusk and occasional late-night sprints. Players can name a favorite, choose among available appearances, and display up to two cats at once. The app is designed to stay mostly out of the way while still making room for these small interruptions.
That desktop-companion format puts Sill Cats in a different frame from a conventional session-based game: it can accompany other computer activity rather than asking for a dedicated play session. The store also describes it as single-player, reinforcing its personal, screen-side character.
