About this game
Idle Cat Merge is a cozy game where you combine cats to unlock rare breeds and slowly grow your own feline shelter. Each merge brings you closer to a more unusual companion, and the puzzle side stays light enough to enjoy at your own pace.
What keeps you coming back is the idle system. Earnings keep ticking up even when the tab is closed, so you return to a pile of resources ready to spend on new cats, upgrades, and room for more residents. Short sessions feel rewarding, and longer ones let you plan bigger expansions.
The game runs free in your browser with nothing to install. It works with a mouse or touchscreen, so you can pick it up on a phone during a break or settle in at a computer for a longer run.
How to play
Click or tap two matching cats to merge them and unlock a rarer breed. Merging generates currency, which you can spend on new cats and upgrades for your sanctuary. Use the mouse on desktop or tap on mobile.
