Every street cat has a story. Be part of it.
Snap a street cat and our Cat Lab finds out who it is. Found a new one? You name it. Every cat gets a CatDex ID and a story that grows with every sighting.

How it works
From street cat to your CatDex.
-
The app checks it’s really a cat. No cat, no catch.
-
Our Cat Lab finds out who it is: a cat new to the CatDex, or one others already know.
-
A new cat? You found it first, so you name it.
-
Every sighting, by anyone, adds to its diary and its place on the map.
Real cats, caught by real players.
