Welcome to the complete Animal Hospital (Anomaly) wiki. You work the night shift at a veterinary clinic: most visitors are ordinary animals, but a few are anomalies — monsters wearing a familiar face. Screen each patient at the window, reject the fakes with the Shutter, treat the real ones in the treatment rooms, and keep your Sanity above zero until the shift ends. This site is organised around the exact questions players search for, so you can jump straight to the answer.

The core loop in one minute
- Check in patients at the reception desk — each is a normal animal or an anomaly in disguise.
- Run the five-point check: your eyes, the check-in photo, the CCTV feed, the paperwork and the audio.
- Admit or reject — hit the red Shutter for anything suspicious. Rejecting a real patient is safe; admitting an anomaly is not.
- Treat the real patients across the rooms — Basic Medical/DNA, X-Ray, Heart Monitor and Surgery.
- Manage Sanity with coffee and food, survive timed events, and reach the end of the shift for cash.
Why detection is a memory game: the game reuses categories of tells. Three eyes, hollow sockets, realistic teeth or a too-wide grin are always wrong. A camera feed with a black box over the eyes, stretched limbs or a figure staring into the lens is always wrong. Learn the baseline of a normal patient and the anomalies stop blending in.
The five-point check, explained
Every patient is cleared — or caught — through five independent channels. A real animal passes all five; an anomaly fails at least one. Learn what each channel is for and the tells stop slipping past you.
👁️ The window
Your own eyes on the patient in front of you. Watch for three eyes, hollow sockets, human teeth, a drawn-on smile, sudden twitching or a hunched posture — and hold your gaze four to five seconds, because some tells flash by in an instant.
📷 The photo
Photograph every patient and compare the developed shot to the live animal. Wrong eyes, ears or colour — or a grotesque face that only shows on film — are all rejects. Note: as of 6/22/26 static alone no longer guarantees an anomaly, so confirm with a second tell.
📹 The CCTV feed
Some anomalies only break on camera: a black box over the eyes, a stretched body, a solid-black void, a staring Skinwalker or twitches you can't catch in person. Switch to the waiting-room feed for a clean look at the eyes.
📋 The paperwork
Your backstop for anomalies that pass every visual check. Cross-read the clipboard: if the patient isn't on the appointment list, or the species and details don't match, reject — the booking beats appearances.
And the fifth — audio. A deep, low-pitched, distorted voice rides along with most appearance anomalies. If the voice is wrong, the patient is wrong, even before you finish looking.

Anomaly tells you'll see most
Six of the most common disguises, pulled straight from our database of 25 confirmed anomalies. Learn these on sight — then tick what you spot in the Anomaly Identifier for an instant admit-or-reject call.
At the windowThree Eyes
Three glowing red eyes instead of the usual two.
The extra eye is often slightly mismatched in size or height, and the patient's real eyes are sometimes still visible behind the glow. Almost always paired with a low, distorted voice.
▶ Reject on sight — always an anomaly, no further checks needed.
At the windowWide Eyes & Drawn-on Smile
Big black-pupil eyes, heavy eye-bags and a large drawn-on smile.
One of two "unnatural face" variants. It loses its real face and keeps staring at you as you move. A distorted voice confirms it.
▶ Reject immediately — no camera check required.
PhotoUnnatural Photo
A normal-looking patient whose photo shows a grotesque face.
The live animal looks fine, but the developed photo reveals a toothy grin, uneven eyes, a human mouth or a heavily blurred face. This is why you photograph every patient, even the calm ones.
▶ Reject the moment the photo turns.
PhotoCursed Photo
Bloodshot eyes and a grotesque grin in the photo.
Reading a cursed photo costs 10 Sanity, so let it develop on the desk and judge it there first. If it looks wrong lying down, close the shutter without ever picking it up.
▶ Reject — never pick up a cursed photo mid-process.
CCTVVoid / Black Body
The whole body is solid black on camera.
Every feature is erased, which makes it one of the easier camera tells. A rarer "disfigured void" variant is partly malformed and even easier to catch.
▶ Reject.
CCTVSkinwalker on CCTV
Shows as a sharp-toothed, long-tongued Skinwalker only on camera.
Wide jaws, sharp teeth and a lolling tongue that appear on CCTV but not in person or in the photo, and only once it reaches the check-in spot. Use the lobby/waiting-room camera for a side view.
▶ Reject — never admit a camera Skinwalker.

Frequently asked questions
What is Animal Hospital (Anomaly)?
A Roblox co-op survival-horror game by Animal Anomaly. You run a veterinary clinic's night shift, admitting real animal patients and rejecting anomalies disguised as patients before they get inside.
How many shifts are in Animal Hospital?
There are 5 main story shifts, after which the game continues into endless, escalating nights with no hard cap. The true-ending route plays out on Shift 5; score-chasing teams push to Shift 10 and beyond. See the How to Play guide for the full breakdown.
Are there any working Animal Hospital codes?
No. As of June 2026 the game has no in-game code-redemption menu, so any "active code" list you see elsewhere is unverified. See our codes page for the live status.
How do I spot anomalies?
Run the five-point check — window, photo, CCTV, paperwork, audio — and reject the moment any layer fails. Our Anomaly Identifier walks you through it.
What happens when Sanity hits zero?
Your run ends. Sanity drains from anomaly contact, some camera feeds and cursed photos; restore it with coffee and food.
Is there an official Trello?
There is no confirmed public Trello board. The authoritative channels are the Roblox game page, the Animal Anomaly group and the official Discord — see the status hub.
