about catz.io
the internet's cat rater
Welcome to catz.io. We believe every cat deserves to be judged. Not in a harsh way, obviously. In a loving, slightly obsessive, deeply scientific way.
Upload a photo of your cat and our panel of expert judges will deliver a verdict on their cuteness, fluffiness, gremlin factor, loaf form and royal energy. Your cat's scores are saved to our leaderboard, where they compete against cats from around the world for the ultimate title of Cat of the Week.
catz.io was built for cat lovers, by cat lovers. We take cat rating very seriously. Your cat does not.
