Catmaster: Cat Breeding Sim

Catmaster is a cat breeding game and cat simulator where every kitten is the result of real cat genetics. Plan pairings, discover coat colors and traits inherited from parents, and build the cattery of your dreams.

BREED CATS WITH REAL GENETICS

Each cat carries a unique genotype. Colors, patterns and traits follow real inheritance rules, so every litter is a surprise. Ragdolls, American Shorthairs and Chartreux each come with breed-specific genetics, and more cat breeds are on the way.

CARE AND TRAIN

Feed, groom and play with your virtual cats to build trust and keep them in shape. Raise kittens, teach them commands and prepare adult cats for competitions.

COMPETE AND WIN

Enter cat shows, beauty pageants and agility contests. Climb the rankings, earn trophies and prove your cat breeding skills against other players.

TRADE AND COLLECT

Sell cats on the market, bid in auctions and offer your tomcats as studs. Complete daily quests, open mystery boxes and collect hand-drawn accessories and backgrounds for your cats.

DRAWN BY HAND, NOT BY AI

Every cat in the game is a unique, hand-crafted illustration. Coat colors, patterns and markings are drawn as separate layers and combined based on your cat's genes, so every kitten you breed is genuinely one of a kind. No AI-generated art anywhere in the game.

A CAT GAME FOR BREEDERS AND COLLECTORS

If you enjoy pet games, animal breeding simulators and collecting rare cats, Catmaster gives you a living cattery to run: pedigrees, litters, shows and a player-driven market.

Catmaster is free to play with optional in-app purchases and no ads. New breeds and features are added regularly. For players aged 16 and up.
