A Building Full of Cats 2

A Building Full of Cats 2 released on Steam on June 16, 2025, a $6.99 hidden-object sequel from Devcats, the studio behind A Castle Full of Cats and the wider Full of Cats series. The pitch hasn't changed: wander through richly detailed, cluttered scenes finding hidden cats and objects, with a light story about caring for a building's feline residents strung between rooms. What has changed, according to a strongly positive 704-review English pool (689 positive, 15 negative, Overwhelmingly Positive), is scale — this sequel is roughly six times longer than its predecessor, and reviewers largely agree the extra content earns its keep, with a handful of real technical caveats attached.

The core hidden-object loop draws consistent praise for how it's been expanded without losing its identity. Reviewers repeatedly highlighted the density and cleverness of the pop-culture references packed into each themed apartment, with one describing an entire gaming-themed unit containing "dozens of references to games and diff consoles/handhelds" and calling the level of detail "a work of art." Another reviewer, comparing this entry directly to the earlier Building Full of Cats, called it "amazing. Improves on the original in every single way," specifically praising added zoom functionality, expressive cat animations, and the introduction of human characters into the story for the first time. The added minigames — including a rhythm-based orchestra sequence and various puzzle-box interactions — drew specific praise for breaking up the core seek-and-find loop, with several reviewers noting they added welcome variety without overstaying their welcome.

The game's charitable angle also came up unprompted in a striking number of reviews. Multiple reviewers cited the fact that part of the proceeds support real cat rescue and welfare organizations as a genuine factor in their purchase decision, with one German-language reviewer summarizing it simply: buy the game because it supports animal protection and cat-help projects, "and that alone is reason enough to buy." That kind of unprompted, repeated mention across a review pool is a meaningful signal that the developer's reputation and mission resonate with its audience beyond the gameplay itself.

Set against that goodwill, the pool's most consistently corroborated complaint is a cluster of technical issues. Several independent reviewers reported the game crashing to a gray screen when moving between rooms, with one writing they'd "complete a room, go into another room, and be greeted by a gray screen. Any attempts to leave the grey screen just crashed the game." Others reported similar crash patterns after patches were supposed to have fixed them, along with a report that the game is entirely unplayable in windowed mode below 1080p resolution, and a more recent review noting the game can't be minimized or tabbed out of without issue. That this same category of instability shows up across reviews with a wide range of playtimes and dates, both before and after patches, makes it a fair and well-sourced weakness rather than an isolated hardware fluke.

A second, smaller but still corroborated complaint concerns the precision required to actually find some of the harder hidden cats. Multiple reviewers separately flagged narrow, unforgiving click hitboxes, with one writing bluntly that "you don't know where the cats are hidden so you have to click every places and for time to time you missed just because the click box is too narrow." A different reviewer made an almost identical point about a lack of visual cues signaling a hidden cat's presence, concluding that without better feedback, "it's no longer fun; it's work." A generous built-in hint system does soften this in practice, and most reviewers who raised the complaint still recommended the game overall, but it's worth flagging for players who found earlier entries in the series more forgiving.

A smaller number of reviewers raised more subjective or one-off concerns worth noting for completeness. Several found certain rooms' color palettes visually harsh over longer sessions, describing them as an "eyesore" or simply "hard on the eyes." One especially detailed negative review raised a more serious, unverified claim: that one of the game's parody songs may have used undisclosed generative AI, arguing the lack of any disclosure on the store page denies players who care about that issue the ability to opt out knowingly. No other reviewer in the sampled pool corroborated this specific claim, so it's reported here as a single, unverified point of concern rather than an established fact, but it's serious enough that prospective buyers who care about the issue should be aware it's been raised.

Not every reviewer felt the sequel improved on its predecessors, and it's worth representing that minority view fairly. A returning fan of the series argued the theming here felt more repetitive room-to-room than in A Castle Full of Cats, and that the game's occasional attempts at gentle life lessons had tipped into feeling "extremely preachy," concluding that Devcats "can, and has, done better." Another reviewer who had enjoyed the earlier titles in the series felt the fifth-floor apartment density crossed from cozy into uncomfortable, joking that sixty-four cats crammed into a small building starts to resemble hoarding rather than a cat sanctuary. These are minority, more subjective readings set against a much larger chorus of praise, but they're a useful counterweight for anyone deciding whether this specific entry, rather than the series in general, is the right one to start with.

Taken as a whole, A Building Full of Cats 2 is a clear step up in scale and ambition from its predecessor, and the vast majority of its review pool treats it as one of the stronger entries in the Full of Cats catalog. The reference density, expanded story, and charitable angle give it real staying power beyond a typical three-hour hidden-object game, but the well-documented crash reports and hitbox frustrations are frequent enough across the pool to be worth going in aware of, particularly for players on less powerful hardware. For genre fans and returning series players, it's an easy recommendation at its modest price; for newcomers who prioritize a bug-free experience above all else, it's still worth a look, just with realistic expectations about the rough edges.
