01 · The pitch
What is a Cat Gatekeeper?
A Cat Gatekeeper is a Pet Gatekeeper made from your real cat. The Pet Gatekeeper Chrome extension hijacks your screen with your Cat Gatekeeper the moment you've been scrolling a watched site too long — a short, silent video of your cat in the way of your scroll, until your time-out ends.
02 · Why it works
Why people make a cat gatekeeper
Cats are weirdly good at this. They don't shout — they just sit there, content, taking up the entire screen. Watching them sit is enough to break a scroll spiral that no banner or counter ever could.
A loaf of a cat covering the page does what a 'you've been on X for an hour' warning never will: it doesn't argue with you. It just sits there. You close the tab.
03 · Where it earns its keep
Where a Cat Gatekeeper fits your day
The home office.
A Cat Gatekeeper is built for the people who already work next to a cat but somehow still spend the workday three taps deep into X. The extension catches the scroll mid-thumb-flick and reminds you the cat is right there. People report breaking month-long scroll habits in a week.
Late-night doomscroll.
A Cat Gatekeeper at 11pm is calmer than any productivity nudge. The video is silent on purpose — it won't wake the household, just put your cat between you and another forty minutes of Reddit.
Lunch-break check-ins.
When 'I'll just eat and watch one TikTok' becomes thirty TikToks, a Cat Gatekeeper showing up is the closest thing to your cat actually walking across the laptop. Small, but it adds up.
04 · How it works
How to make your own cat gatekeeper, step by step
- 01
Pick the right photos
1–4 clear, well-lit photos. Front-facing or 3/4 angle works best. Avoid heavy shadows and motion blur.
- 02
Upload and confirm pose
We generate two green-screen poses from your photos. Approve the look — or regenerate within the included free retries if you want different poses.
- 03
Generate two short videos
An intro clip and a loop. Tune the chroma-key live in your browser — different fur colors need different settings.
- 04
Redeem in the extension
Get an 8-character code. Paste it into the extension's redemption screen and your cat is the next thing you see when X tries to keep you.
05 · Tips
Tips for great cat videos
- Soft, even light beats direct sunlight — fewer hard shadows for the chroma-key step.
- Solid backgrounds (couch, wall, floor) make the green-screen tuning easier.
- Black cats and tortoiseshell coats need a slightly tighter chroma threshold; the live preview makes this easy.
- If your cat won't sit still, the photo flow only needs four still frames — easier than catching a video moment.
