The RunCat Alternative that walks your desktop
RunCat is the classic: a cat in the menu bar that runs faster as CPU load climbs, so you can read your Mac's load at a glance. The current version, RunCat Neo, is free and open source, with optional tip purchases on the App Store, and it requires macOS 26. Notchy's desktop pet, new in 1.0.178, takes the same idea out of the menu bar and onto your desktop — a pixel cat or dog that reads CPU, battery, charging, focus timers, music and video, and shows each one as something it does.
Looking for RunCat itself? It lives on the App Store.

Why use Notchy instead of RunCat?
- Reads the whole Mac, not one number
It pants with sweat drops when the CPU is pegged or macOS is throttling, shivers when you're unplugged and nearly flat, perks up when you plug in, sits still during a Pomodoro, dances to music and watches along when a video plays.
- A pet you look after
Feed, play, pat and nap it. Food, energy and friendship meters, a daily care streak, and a speech bubble that says what it's reacting to.
- Things to collect
23 pixel pets, a 1-in-50 shiny for each, hidden discoveries, seasonal hats, fetch and a memory game.
- Where RunCat is better
RunCat stays in the menu bar and takes no desktop space, offers dozens of runners, and supports your own metrics. If you want a precise load meter, not a companion, it's the tidier tool.

The honest verdict on RunCat
RunCat is a beautifully small idea done well, and if a running cat in the menu bar is all you want, keep it. Notchy's pet is for people who want the companion version — one that reacts to heat, battery, music and focus, and that you can look after.
RunCat alternative — FAQ
Is RunCat free?
RunCat Neo is free on the Mac App Store and open source; the listing offers optional in-app tips ($3.99 and $19.99). It requires macOS 26 or later.
Does Notchy show CPU usage like RunCat?
Yes, twice over: the pet sweats when the CPU is hot, and Notchy's system monitor shows exact CPU, GPU, memory and network numbers in the notch.
Does the Notchy pet sit in the menu bar?
No — it lives on the desktop, above your windows, and wanders unless you pin it in place. Click it for its care card.
Will a desktop pet slow my Mac down?
Notchy's pet pauses every timer and its animation when the display sleeps or the screen locks, and parks its animation in Low Power Mode.
Which Macs does it run on?
Notchy runs on macOS 13 Ventura or later, Apple silicon and Intel. Tilt-to-play needs an Apple silicon Mac's motion sensor.
