There's a Cat in My PC is a free-to-play indie casual simulation game for PC that places a collection of virtual cats directly onto the Windows desktop. Players adopt and care for cats that move across open windows, interact with the environment in subtle ways, and provide ongoing companionship without interrupting work or other applications. The experience centers on daily collection, personalization, and light management of a growing feline household that remains active in the background.
Gameplay
Cats appear on the desktop and behave independently while respecting user activity. They walk along the top edges of open windows, jump between them, and settle into naps without stealing focus from active programs. Mouse clicks register only on the cat's own pixels, allowing uninterrupted typing or navigation. Adoption happens once per day through a free draw that requires an internet connection, encouraging regular check-ins to expand the collection. Each of the 98 cats features distinct colors, patterns, and personality-driven reactions that influence how they move or respond to the player.
Players can assign names to individual cats and engage in conversations by registering a free Google API key. This enables the cats to reference real-world details such as local weather when asked or deliver fortunes drawn from Eastern philosophy. A dedicated cat house serves as a resting area where felines enter and exit on their own. Furniture items like cat towers can be placed inside, though they degrade over time and require Churu treats for repairs. Cats continue their desktop routines even when the house is in use, creating a layered sense of activity across both the overlay and the contained space.
The system stays lightweight on system resources, supporting all-day operation with minimal CPU and memory demands. Offline functionality preserves normal cat behaviors when an internet connection is unavailable, though daily adoptions pause without connectivity.
Game Modes
The core experience revolves around steady collection and observation rather than structured competitive or narrative modes. Daily free adoptions form the primary progression loop, with players returning each day to add new cats to their roster. Interaction options expand through naming, chatting, and furnishing the shared house space, turning routine desktop time into a gentle management routine.
Rehoming adds a community layer as the collection grows. Excess cats can be listed on the Steam Community Market for other players to adopt, while new arrivals can be obtained the same way. This creates an organic economy around unique personalities and appearances without any direct payment system inside the game itself. The focus remains on passive enjoyment and incremental expansion rather than timed challenges or separate play styles.
Key Features and Mechanics
Personality variation among the 98 cats ensures each addition feels distinct, with reactions that differ based on individual traits. The chat system adds depth for those who set up the optional API integration, turning brief desktop glances into short exchanges about weather or fortunes. Furniture maintenance introduces a light upkeep element that ties into the house area without demanding constant attention.
Market trading extends the simulation beyond a single player by allowing cats to move between households. This mechanic rewards consistent daily play by providing options to curate or trade for preferred personalities and patterns. The non-intrusive overlay design keeps everything compatible with normal computer use, making the game suitable for long sessions alongside work or browsing.
Is It Worth Playing?
There's a Cat in My PC suits players seeking a low-pressure desktop companion that runs continuously in the background. The free daily adoption system, combined with the absence of any payment options, removes financial barriers and emphasizes patience and routine. Those who enjoy collecting varied characters and light customization will find value in the 98 unique cats and their individual behaviors.
The lightweight performance and offline support make it practical for extended use, while the optional chat and market features add replayability for users who want more interaction or community exchange. It appeals most to casual simulation fans who appreciate relaxing, always-present elements over intense gameplay loops. The experience delivers steady, undemanding enjoyment for anyone looking to share their screen with a growing group of digital cats.
