Catopia Demo

A cat on your desktop.

Catopia is a transparent-overlay desktop pet. There's no separate game window — a pixel cat simply lives on top of your wallpaper. Click any empty space and your desktop works as usual; the cat is just there, keeping you
company.

🐾 Five cats, five personalities

Choose one of five cats — Cheese, Cloud, Pumpkin, Cotton, and Oreo. Each has its own decay rates for hunger, happiness, and cleanliness, plus unique idle chatter and behaviors.

💝 Care and affection

Feed, play, and wash to manage your cat's condition, and pet it to build affection. Play together with ball-chase and mouse-hunt mini-games. The panel records your days together and your bond.

🌈 Two kinds of goodbye

Your cat won't be with you forever. Let its condition collapse from poor care and it falls ill and crosses the rainbow bridge; let its affection run dry from neglect and it quietly leaves home. Which farewell you meet is in your hands.
