What is Neighborhood Cat Atlas?
Neighborhood Cat Atlas is a community map for recording stray-cat sightings with your neighbors. It recognizes the cat in your photo right on your device and matches whether it's the same individual, so the atlas grows together.
13 cats · 6 sightings · 13 active in the last 7 days · Counted as of Aug 1, 2026
How it works
Snap or upload
Photograph a cat you meet, or upload a picture.
Recognized on your device
On-device AI finds the cat and computes its features inside your browser. The original photo never leaves your device.
Add to the atlas
It matches against known cats — adding a sighting if it's a match, or registering a new cat if not.
How your location stays safe
A stray cat's exact location can be dangerous. Public locations are snapped to a ~250m grid and shown only as an approximate area; exact coordinates are never exposed, not even on the server. Location data (EXIF) in uploaded photos is stripped server-side.
Frequently asked
- Do my photos get uploaded to a server?
- Cat recognition (feature extraction) runs only on your device. You may upload a representative photo to help build the atlas; its embedded location data (EXIF) is removed server-side.
- Can anyone see a cat's exact location?
- No. Public locations are blurred to a ~250m grid, and exact coordinates are visible to no one.
- Can I browse without an account?
- Yes. The atlas and map are open without logging in. You only need an account to add a sighting or leave a comment or photo.
- Does it cost anything?
- It's free. Recognition runs on your device, so server costs stay near zero.
