Every Animal Hospital anomaly, sorted by the check that reveals it

An Animal Hospital anomaly can look completely normal at the glass and only give itself away in a photo or on CCTV. This page covers all 20 entries in our list — what shows up at the window, what only shows up in a photo, and what only shows up on camera — plus what actually happens if you admit one by mistake.

Last updated 2026-07-03

How we know this: our own reconstruction of the anomaly list, put together from public community write-ups. It is not an in-game audit, it is not complete, and it can be wrong. A clear result here is not a guarantee the patient is safe — finish every check yourself.

TL;DR

20 entries: 18 patient-identification tells (6 Appearance, 5 Photo, 7 CCTV) plus 2 hazards — Head Banger and the red-eyed figure on the feed — which the write-ups class as monsters, not patients you screen, so the checker leaves them out. Mismatched ears can show in the photo as well as on camera, so check ears at both steps.
A patient can carry more than one tell at once, so one clean check is not proof — the quick reference table below lists every sign next to the check that catches it.
Search or filter below, then tap Found on any card to log it in the tracker.
Your tracked progress saves in this browser only, so it is private and does not need an account.
Every card links to a full page with the exact sign, the correct call, and the in-hospital consequence if you admit it anyway.

Every Animal Hospital anomaly: sign, check, and consequence

Skim this before a shift or keep it open in a second tab. Every row is one anomaly, the check that actually reveals it, and what happens in the hospital if that patient gets admitted anyway.

Anomaly	Check	Sign	If admitted
Three Eyes	Appearance	Three slightly mismatched glowing red eyes rather than two. The extra eye sits on the forehead and the original pair is sometimes still visible underneath it. Some write-ups also report a low-pitched, distorted voice.	Admitting it can spawn hostile monsters loose in the hospital.
Hollow Face	Appearance	Empty, hollow eye sockets and a lifeless, blank, open-mouthed expression. Write-ups describe a visible hunch and slight twitching as part of the same tell.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Human Teeth	Appearance	Behaves normally but has small, wide circular eyes and unsettlingly realistic human teeth instead of animal ones.	Triggers a death ritual, or the patient becomes a shapeshifter, once admitted.
Creepy Smile	Appearance	A wide, unnatural, drawn-on grin with big bulging eyes, black pupils and prominent eye-bags.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Googly Eyes & Sharp Teeth	Appearance	A crooked, distorted smile with rows of sharp teeth and mismatched glowing eyes, usually paired with a warped, distorted voice. BloxGuidesGG adds that its head follows you around the room.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Twitching	Appearance	Short, repeated jerking of the head, neck and both arms while the patient stands still. BloxGuidesGG also reports an elongated neck on some variants.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Head Banger	Appearance	Bangs its head against the reception glass. This is a hazard event, not a patient you identify and admit - every write-up we read classes it as a monster/hazard rather than an appearance anomaly.	Interacting with it unprepared drains your sanity; giving it coffee makes it wander off safely.
Different In Photo	Photo	The developed photo does not match the patient at the glass: eye shape, pupils or eyelids, ear shape or colour, markings, mouth shape, or in the worst case an entirely different animal. The difference can be as small as one missing pupil.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Different Eyes	Photo	The eyes in the developed photo do not match the patient at the glass - a changed eye shape, an added eyelid, or a missing pupil. Everything else about the patient can look right.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Unnatural Photo	Photo	The patient looks like a normal cartoon animal at the window, but the developed photo shows an eerie, unnaturally realistic face - distorted features that are not visible in person.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Photo Static	Photo	A grainy, staticky film across the developed photo.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Cursed Photo	Photo	A disturbing print: bloodshot eyes, a grotesque smile, blurred features. Picking it up before it finishes developing costs 10 sanity instantly.	Picking the photo up while it is still processing costs 10 sanity, admitted or not.
Void Body	CCTV	On camera the entire body turns solid black, hiding every feature. fdaytalk reports a rarer disfigured version of the same tell.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Deformed Body	CCTV	The body looks heavily stretched or distorted on the feed and nowhere else. The distortion changes shape each time you switch camera angle or reopen the feed, and that change is the confirmation.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Skinwalker	CCTV	Looks completely normal at the window and in the photo, then shows a wide-open mouth full of sharp teeth, and a long tongue, on the camera feed once it reaches the check-in position.	Becomes a hostile Skinwalker loose in the hospital once admitted.
Different Ears	CCTV	Ears or horns look wrong or mismatched. Write-ups place mismatched ears in BOTH the photo and the camera feed, so compare ears at both steps - do not treat this as camera-only.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
The Starer	CCTV	Always faces the camera. Switch to another feed and it turns to look at that one too, while a normal patient faces the reception desk.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Black Eyes	CCTV	On the feed a black bar covers the face, with a pair of realistic eyes drawn on top of it or showing through it.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.
Black Body, Red Eyes	CCTV	A black figure with glowing red eyes and monstrous teeth that appears on the camera feed. The camera zooms in on it and your sanity drains while you keep watching. This is a hazard on the feed, NOT a patient you admit or reject - the write-ups file it with the monsters, not the identification tells.	Drains sanity and zooms the CCTV feed in while you are viewing it.
Twitching (CCTV)	CCTV	The same jerky twitching motion, but it only shows on the security footage - the patient looks still at the window.	No specific in-hospital effect is documented for this one — treat any confirmed sign as an automatic reject.

Where this list comes from

This list is our reconstruction, not an in-game audit. We did not sit in the game and record every patient. We read the public community write-ups and kept an entry when more than one write-up that had clearly not copied the other described it the same way — same trigger, same category. That is a reasonable way to build a list, but it is not the same as knowing, so treat everything here as a memory aid rather than as game data. It can be wrong, and it is not complete.

That method is also why the count looks lower than a page claiming 25-30 anomalies — most of that gap is double-counting, not extra content.

What we deliberately left out. Some guides split "different ears," "different eyes," and "wrong photo" into three separate anomalies. We fold those into one entry — Different In Photo — because the check is identical: compare the developed photo to the patient at the glass. Splitting it into three inflates the count without adding a new thing to watch for.

We also keep hospital hazards — the Bed Monster, Ghost, Shapeshifter, Stalker, Tendril, and similar threats — off this page on purpose. They are consequences of a missed anomaly, not signs you check for at the window, so mixing them into an "anomaly" list makes the identification job harder to skim, not easier. Where a specific hazard is the documented result of missing a specific tell, it is named in the "If admitted" column of the table above instead.

Anything we could not corroborate against a second independent source stays out of the list rather than going in as a guess.

Where the guides disagree

Most guides state every claim as fact. We would rather tell you when a report has not cleared our two-source bar yet, because a single-source claim treated as confirmed is how the double-counting in the "25-30 anomalies" pages above happens in the first place.

Unprocessed Photo

The claim: A photo that fails to render at all, so there is nothing to inspect. The claim is that you should treat it as an anomaly if the next patient's photo develops normally.

Why it is not in our list: Only fdaytalk describes this. Four other write-ups do not list it, so we are not publishing it as a tell yet.

Reported by: fdaytalk

Hunched Posture (on its own)

The claim: A patient standing with a visible hunch, listed as an appearance tell in its own right.

Why it is not in our list: Only fdaytalk lists it separately. Beebom and BloxGuidesGG instead fold "hunched" into Hollow Face, which is how we have it. We are treating it as part of Hollow Face, not a separate anomaly.

Reported by: fdaytalk

Hollow Face on CCTV

The claim: A patient whose hollow face is only visible through the security cameras, separate from the version you can see at the window.

Why it is not in our list: Only Beebom describes a camera-only version. The others only describe Hollow Face at the window.

Reported by: Beebom

A window-side version of The Starer

The claim: A patient whose eyes track your character at the reception window itself, rather than only on the camera feed.

Why it is not in our list: Only animal-hospital.me describes it. Every other write-up we read describes the camera-tracking version only.

Reported by: animal-hospital.me

One thing worth knowing if you have read other guides: several names that look like missing anomalies are just other names for tells already in the list above. "Censored Eyes" is Black Eyes. "Disguised Shapeshifter" is the Skinwalker. "Incorrect Photo", "Different Eyes" and "Unnatural Photo" are all the same photo comparison. Every entry above lists the other names it goes by, so a longer list elsewhere is usually the same set of tells counted differently — not extra content you are missing.

FAQ

What counts as an Animal Hospital anomaly?

An Animal Hospital anomaly is a patient that looks or acts like a normal animal but carries one confirmed tell — a facial detail at the window, a change that only shows up in the developed photo, or a mismatch only visible on the security cameras. Any one of those is enough grounds to reject.

Does the anomaly tracker save my progress?

Yes, but only on the device and browser you are using right now. Checkmarks are stored locally, so nothing is uploaded and your phone and PC keep separate progress.

Why did my tracked anomalies disappear?

Clearing your browser's site data, switching to a private window, or moving to a new device wipes the saved list, since it never leaves your browser in the first place. Use the reset button above the grid if you want to start over on purpose.

Can I filter down to anomalies I have not found yet?

Turn on "Show anomalies I have not logged yet" under the progress bar. Stack it with a category tab or the search box when you are hunting the last few CCTV-only tells.

Is this the full list of Animal Hospital anomalies?

It covers 20 entries as of 2026-07-03: 18 patient-identification tells split into Appearance, Photo and CCTV, plus 2 hazards that are not patients you screen. This is our own reconstruction from public community write-ups, not an in-game audit, and it is not complete - other write-ups name tells we could not pin down, which we list under "Where the guides disagree" instead of publishing as fact.

Can one patient show more than one anomaly at once?

Yes. An Animal Hospital anomaly can stack — a single patient can carry an appearance tell and a CCTV or photo tell at the same time, so finding one sign is enough to reject, but do not stop checking early just because the window looked clean.

Are the Bed Monster, Shapeshifter, or Skinwalker anomalies?

No. Those are hospital hazards that show up after a wrong call, not signs you check for at the window. This page only covers the identification tells; the consequence column in the table below tells you which of those hazards a missed sign can trigger.
