Game Overview
Every room becomes a small visual puzzle in this gentle hidden-object adventure, where the only real mission is to locate and pet an enormous population of cats. A Building Full of Cats trades timers, pressure, and elaborate scoring for a warmly illustrated apartment block packed with feline mischief. Cats peer from shelves, curl up in furniture, blend into clutter, and occupy spots that reward careful scanning rather than fast reactions. The mood stays cozy and cheerful throughout, making it an easy game to pick up for a few minutes or settle into for a longer, low-stress session.
Players move through a multi-floor building, inspecting each hand-drawn scene and clicking every cat they uncover. Finding a cat adds it to the level’s running total, while missed animals encourage you to revisit rooms with a sharper eye and a better understanding of how boldly the art hides its targets. More than 360 standard cats are spread across over six floors, and additional secret felines give completionists a reason to investigate odd corners, background details, and apparently ordinary objects. There is no combat, resource management, or punishing fail state; progression comes from clearing areas and satisfying the urge to turn every counter into a complete total.
Its strongest feature is the density of personality in such a simple idea. The black-and-white line art keeps scenes readable while still allowing cats to disguise themselves in surprising ways, and the building format gives each floor a distinct little domestic story rather than presenting isolated puzzle screens. Secret cats add a mild challenge without disrupting the relaxed pace, so success feels more like a satisfying observation test than a hardcore hidden-object gauntlet. Fans of Unpacking’s calm environmental storytelling, cozy puzzle games, or real-life cat spotting should find plenty to enjoy, while even genre newcomers can finish it comfortably thanks to its accessible one-click design.
