Merge Cats Idle Evolution is a cozy and satisfying merge & collection game where you combine adorable cats to discover new breeds, complete achievements, and build the ultimate feline collection.
Every merge unlocks new surprises, new cats, and new milestones. Perfect for players who enjoy progression-driven, stress-free gameplay.
Merge your way through multiple stages, evolve your cats step by step, and expand your collection with increasingly rare and valuable breeds.
And for collectors: your evolved cats can be added to your Steam Inventory and traded or sold on the Steam Community Market.

Sell on Steam Market: These special cats can be listed and sold on the Steam Community Market, letting dedicated players turn their collection into real value.
