Idle Merge Cats

Idle Merge Cats centers on building a feline collection through a simple merging loop. Players spend Hearts to summon kittens, then drag and drop two cats of the same level together to create a higher-level cat. Each merge can reveal a new breed or evolved form, turning repeated matching into a steady path toward discovering rarer cats.

The game features hundreds of collectible cats, including orange tabbies, Ragdolls, black cats, and cats with unusual eye colors. Individual cats have their own animations, giving the growing collection visual variety. As players gather more cats, they unlock new cattery backdrops, with settings that include a countryside cottage, beach, magical castle, and whimsical treehouse. The source describes a single casual collection-and-merging experience, with Hearts serving as the resource for summoning and cat levels determining which merges are possible.
