Cats Lock is a Mac desktop app that blocks your keyboard with ⌘L so your cat can walk on it without sending chaos into your work. A friendly overlay shows when locked; Stealth Lock keeps it silent and invisible for meetings. $2.99 one-time, sandboxed, no subscriptions. Menu bar access included.

Cats Lock is a Mac desktop app for people who share a desk with a cat. With one press of ⌘L from the main window or the menu bar, the keyboard locks instantly so your cat can settle in for a nap, walk across the keys, or knead the trackpad without sending chaos into your active app. A friendly overlay appears while locked, and a customizable warning sound plays on each blocked keypress so you can hear from the next room when your cat has joined the keyboard. Stealth Lock mode keeps the lock silent and invisible, useful during meetings or recordings. The app is fully sandboxed for the Mac App Store, requires no account, runs no analytics, and is sold once at $2.99 with no subscription. Built by indie developer Todd Alexander for him and his cat to enjoy.

Cats Lock is a Mac desktop app for people who share a desk with a cat. The interaction is intentionally minimal: one press of ⌘L from the main window or the menu bar locks the keyboard, so your cat can stretch out, walk across the keys, or settle in for a nap without sending anything into your active app. While locked, a friendly full-screen overlay shows the lock state, and a customizable warning sound plays on each blocked keypress. Useful as an audible cue from the next room when your cat has joined the keyboard while you're away from the desk, or just pure enjoyable and shareable content.

Stealth Lock mode swaps that experience for a silent, invisible variant. The keyboard is still blocked, but no overlay appears and no sound plays, which is helpful if you want to lock the keyboard during a meeting, recording, or call without any visual or audio side effect. Stealth-mode unlock requires the ⌘L shortcut.

Cats Lock is built fully within the App Store sandbox. There is no Accessibility prompt, no analytics SDK, no account creation, and no telemetry. It is sold for $2.99 as a one-time purchase with no subscription tier and no upsells. The app was built by indie developer Todd Alexander for him and his cat to enjoy: a small, complete utility designed to install, fade into the background, and only matter the moment a cat decides the keyboard looks comfortable.

The app is available on the Mac App Store starting May 15, 2026.
