Cat Box Merge

You start by clicking boxes to reveal cats, coins, and other rewards, then drag matching cats together to merge them into a higher-level pet. Coins buy new boxes, while cats resting on beds gradually produce more boxes for you to open. Each world contains ten cats to discover before you can move on, and the game runs in portrait orientation on desktop, phone, or tablet, with mouse taps or touch drags.
