Pets Therapy turns your desktop into a tiny living world. Small pixel-art companions walk, idle, sleep, fall with gravity and react to you — and you can have as many of them on screen as you like. Below is a full breakdown of what the app does.

Core features

ðŸū 100+ pets with real animations

The pet library spans 100+ species, including cats (with 16+ color variants), a T-Rex and other dinosaurs, apes and a chef ape, dogs like the Shiba Inu, pandas, koalas, sloths, sheep, frogs, crows, betta fish, mushrooms and bunnies. Each pet isn't a static image — it has proper animation states (walking, idling, sleeping, eating and special moves like the T-Rex's roar, guitar and fireball).

ðŸ’ŧ Native on macOS, Windows and Linux

This is the big differentiator. Most desktop-pet apps are locked to a single operating system. Pets Therapy runs natively on macOS, Windows and Linux, so you get the same pets and behavior wherever you work. The macOS app is on the Mac App Store; the Windows app is on the Microsoft Store.

ðŸŽĻ Custom pets

You're not limited to the built-in library. Pets Therapy lets you create and import your own pets — your own sprites, your own animations, your own behaviors — using a simple JSON species definition. See the custom pets guide to make your first one.

ðŸ–Ĩïļ Multi-monitor support

On multi-display setups, pets can roam across every enabled monitor, each with its own little population, so your companions aren't stuck on one screen.

âœĻ Random desktop events

Every so often, something fun happens on its own — weather, a UFO, a teleportation portal and more drift across your desktop at relaxed intervals, keeping things surprising without being distracting.

⚙ïļ Adjustable size, speed and behavior

Tune your pets to taste: change how big they are, how fast they move, and which pets are active. Per-pet size overrides let you mix a giant dino with a pocket-sized cat.

ðŸ§Đ Built on a purpose-built pet engine

Under the hood is YAGE, a composition-based entity-component engine designed specifically for desktop pets. Each pet is assembled from small reusable behaviors, which is how the app supports so many species and custom pets while staying light.

ðŸŠķ Lightweight and unobtrusive

Pets animate over your desktop without getting in the way of your work. Like any live animation it uses some system resources, but it's built to stay light during normal use.

Available in 19 languages

The app is fully localized into 19 languages, including English, German, French, Spanish, Italian, Dutch, Portuguese, Russian, Ukrainian, Turkish, Arabic, Hindi, Indonesian, Thai, Vietnamese, Japanese, Korean, Czech and Chinese.
