A desktop pet sim where a pixel cat lives on your wallpaper while you work. Choose one of five cats — Cheese, Cloud, Pumpkin, Cotton, or Oreo. Feed, play, wash, and pet to build affection. Neglect its health and it falls ill; neglect its heart and it walks away for good.

<h2 class="bb_tag" >A cat on your desktop.</h2><br>  <strong>Catopia</strong> 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<br>  company.<br><br>  <h2 class="bb_tag" >🐾 Five cats, five personalities</h2><br>  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.<br><br>  <h2 class="bb_tag" >💝 Care and affection</h2><br>  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.<br><br>  <h2 class="bb_tag" >🌈 Two kinds of goodbye</h2><br>  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.<br><br>  <h2 class="bb_tag" >✨ Features</h2><br>  <ul class="bb_ul">  <li><strong>Transparent overlay</strong> — your cat stays on the desktop while you work<br>  </li><li><strong>5 cats</strong> — distinct stats, lines, and behaviors per breed<br>  </li><li><strong>Care system</strong> — feed ·play ·wash ·medicine ·petting<br>  </li><li><strong>Two mini-games</strong> — ball-chase ·mouse-hunt<br>  </li><li><strong>Affection system</strong> — 0–100, with days-together tracking<br>  </li><li><strong>Living behaviors</strong> — roaming ·napping ·hiding in boxes ·bathroom needs<br>  </li><li><strong>Multi-monitor support</strong> — your cat roams between displays<br>  </li><li><strong>Per-cat sound effects and BGM</strong><br>  </li><li><strong>Offline progression</strong> — stat changes computed while the app was closed<br>  </li></ul><br>  <h2 class="bb_tag" >🔒 Play with peace of mind</h2><br>  All data is stored <strong>locally on your computer</strong>.
