Cat Gatekeeper is a free Chrome extension that places a sleepy cartoon cat over sites like Facebook and Reddit when you've spent too much time scrolling. Released today by developer @konekone2026, it lets you set a timer; when time's up, the tab is covered with a chubby feline, a gentle nudge to take a break. The extension works on Facebook, X, Reddit, YouTube, Threads, and Bluesky, and with Chrome powering nearly half of U.S. browsers, it reaches a huge audience.

Why it works better than blockers that shame you. Cat Gatekeeper skips the scolding. When the timer expires, a big illustrated cat pops up in the center of the page. You can click it away, but the site stays blocked until you reset the timer. The rest of your browser (email, news, and everything else) remains untouched. It's not punishment; the cat doesn't judge. It just sits there, round and unbothered, like a house pet reminding you there's sunshine outside.

The goal, they note, is to make productivity feel less like discipline and more like a light hearted break, a small win for anyone trying to reclaim attention without turning their browser into a surveillance system.

What's next. Right now it's Chrome only, but @konekone2026 has hinted at a Firefox version down the line, which would bring the feline guard to a wider audience. No word yet on mobile apps or other platforms.

The bottom line. If you're looking to curb mindless scrolling without a guilt trip, Cat Gatekeeper offers a simple solution that blends humor with a modest productivity boost. It won't solve your dopamine problem overnight, but it might make you smile before you close the tab, and that's worth something.
