Desktop Pet: DonEatFish Review

A Free Cat Idles on Your Desktop While You Do Something Else

Desktop Pet: DonEatFish is a free-to-play screen ornament: a small animated cat perches in a corner of your desktop, idly fishing for currency while you work, browse, or play something else entirely. That currency cracks open chests for cosmetic items, which in turn dress up the cat and feed into what several reviewers describe as a Steam-inventory-item economy layered on top of the idle loop. It's an extremely low-friction pitch — adopt a kitty, let it earn while you're not looking, check back periodically — released by Steeped Sky Studio on September 6, 2026, with a string of near-daily update notes in the weeks since launch suggesting active, if reactive, post-launch maintenance.

There's an established lineage of these desktop-companion idle games built around Steam trading-card-style economies, and DonEatFish slots into that lineage without doing much to distinguish itself, positive or negative, from the pack it's joined. Seven near-daily update notes landed in the ten days after launch, covering leaderboard fixes and unspecified "update contents" — a patch cadence that reads as reactive firefighting rather than a planned content roadmap, though it does at least show the developer is present and responding to something.

A Thin, Mostly Negative English Pool Dominated by One Alarming Complaint

Desktop Pet: DonEatFish has drawn 34 total Steam reviews (68% positive, "Mixed") since launch, but the English-language slice of that pool tells a much harsher story: just 7 English reviews, only one of them positive. The lone positive review is modest in its praise: "Had my kitty cat fishing on the top left corner of my second screen while I played other games" — a simple, low-stakes endorsement of the game doing exactly what it says on the tin.

The negative reviews are considerably more pointed, and the most serious, recurring complaint concerns security rather than gameplay. Multiple, independent English-language reviewers report their antivirus software flagging the game outright: "This game actively triggered my antivirus," reads one review, while another states plainly, "When I tried to launch the game, my antivirus immediately detected viruses. Warning! I cannot recommend this game." A third goes further, describing what they characterize as persistent, unwanted behavior: "Acts like a trojan horse, random GPU shoot ups, Tries to re-install after removal. seems to have baked in malware." It's important to be precise about what these are: reviewer-reported experiences and characterizations, not an independently verified finding by this outlet — but with three separate reviewers raising security alarms unprompted, in a pool this small, it's a pattern too consistent to omit or soften.

The Core Fishing-and-Cosmetics Loop Works as a Low-Effort Background Toy

Setting the security complaints aside, the mechanical bones of DonEatFish are exactly as advertised: a cat sits in the corner of a monitor, periodically "fishes" for in-game currency without requiring the player's attention, and that currency unlocks chests containing cosmetic dress-up items for the pet. It asks essentially nothing of the player beyond an occasional glance and a currency-spending decision, and the one clearly positive review confirms that this bare-minimum loop does function as a pleasant, unobtrusive second-monitor companion for players who specifically want that kind of ambient idle toy.

That's also close to the full extent of what there is to say positively about the design — it's a functional but extremely shallow implementation of a well-worn subgenre, without a distinguishing hook of its own beyond the cat-and-fish theming. The chest-cracking layer, tying cosmetic drops to an in-game currency rather than real money, is the one structural idea that gives the loop any shape at all, but nothing in the available review text suggests it goes deeper than periodic random unlocks.

Confusing Controls, Thin Content, and an "AI Slop" Accusation From a Long-Time Player

Beyond the security complaints, reviewers describe a genuinely confusing experience even on its own idle-game terms. One reviewer who logged nearly 49 hours of playtime writes simply, "still have no clue how to play this" — a damning admission from someone who spent real time with it rather than bouncing off immediately. Another dismisses it in a single word: "lame." A separate reviewer frames their dissatisfaction as part of a broader pattern in the genre, calling it "a low effort tofu AI slop idle game in a long line of them all about Steam inventory items to make money with no over-sight for poor gamers" — an accusation about the game's own content-generation process, reported here as that reviewer's characterization and not a confirmed fact, alongside an unsubstantiated data-harvesting claim in the same review that this outlet cannot verify and does not endorse.

Taken together, the English-language reviews paint a picture of a game whose core hook barely registers before players either bounce off in confusion or, more seriously, report security software actively intervening at launch.

Verdict

Desktop Pet: DonEatFish delivers on its narrow premise for at least one player — a background cat, idly fishing, undemanding and cute — but the small English review pool is dominated by confused, dismissive, and in several cases genuinely alarming reports of antivirus detections and unwanted background behavior. Being free doesn't offset a security concern raised by multiple independent reviewers; it only lowers the cost of finding out the hard way. Between the thin, unclear core loop and the unresolved security complaints sitting in its own review section, this is one to approach with real caution rather than casual curiosity, regardless of the price tag.
