How to play Animal Hospital? In a nutshell: You are working the night shift at a veterinary clinic. Patients are sent to your reception window, but some are anomalies disguised as animals. You must screen them one by one—admit the real patients, use the red shutter to reject the anomalies—and then send the admitted patients to treatment rooms to be cured via mini-games. All the while, you must deal with roaming enemies and random events, all while keeping your Sanity meter above 0. This is the core of Animal Hospital (a Roblox horror game).
This Animal Hospital how to play guide will take you, a newcomer to anomaly horror games, through a complete shift from scratch: first explaining the core loop and controls, then breaking down reception screening, the eight treatment rooms, Sanity management, enemies and events, and finally providing a step-by-step walkthrough for the first night, common pitfalls, and the pros and cons of playing solo vs. in a group. Treat this page as your starting point for Animal Hospital beginner tips and clinic strategy.
First, get to know Animal Hospital: What are you playing?
Before figuring out how to play Animal Hospital, take a minute to understand the game's foundation. It is a co-op survival horror game on the Roblox platform that focuses on "slow-burn tension" rather than jump scares. It has a heavy psychological horror vibe and is described by players as "FNAF meets spot-the-difference, and you are the vet receptionist."
The game was developed by the Roblox group Animal Anomaly (led by Roytt) and became an instant hit after its release on May 10, 2026, with updates being patched in almost daily. It is completely free, supports up to 30 players in co-op, and runs cross-platform. There is no fixed ending—this is an endless mode where your goal is to survive as many Shifts as possible; the longer you last, the stronger you get.
For newcomers who have never touched the anomaly horror genre, the most important mindset adjustment is: the "monsters" here often won't jump at you right away; instead, they disguise themselves, lurk, and slowly erode your Sanity. Patient observation and careful decision-making are more important than fast reflexes.
This game focuses on a "slow burn" of dread rather than frequent jumpscares. If you are looking for mindless action, you might not enjoy it; but if you enjoy spotting anomalies, making judgment calls, and handling pressure, that is where the fun lies.
Core Loop: Screen → Treat → Survive
Every Shift at Animal Hospital revolves around this three-step cycle. Once you commit these steps to muscle memory, you will have mastered the framework of how to play Animal Hospital.
- ① Front Desk Screening
Stand at the front desk to receive incoming animal patients: if it is a real patient, admit them; if it is a disguised anomaly, lower the red shutter to reject them. Misjudging patients is where most beginners fail.
- ② Treat Patients in the Treatment Rooms
Admitted patients must be taken to the corresponding treatment room to complete their care via minigames. Different rooms require different procedures (DNA, X-ray, Heart Rate, Surgery), each with its own mechanics.
- ③ Survive Events and Roaming Enemies
Random events will occur in the clinic, and roaming enemies (including the Skinwalker) will be moving about. You must work while staying alive, keeping your Sanity above 0. Once your Sanity hits zero, the Shift ends.
The most common mistake for beginners is "tunnel vision": either staring at the window and forgetting to treat patients, or getting lost in a minigame and getting caught off guard by an enemy. The ideal rhythm is to switch quickly between the three tasks—screen a patient, make progress on a treatment, and look up to scan your surroundings and your Sanity meter.
Controls and Inputs: PC and Mobile
This section covers Animal Hospital controls. The PC version has a full keyboard and mouse mapping, while the mobile version uses touch buttons—the latter currently lacks an official key map, so we have documented it as is.
| Action | Key / Method | Description |
|---|---|---|
| Movement | W A S D | Move forward, backward, left, and right; essential for exploring the clinic and traveling between treatment rooms. |
| Jump | Space | Clear obstacles or quickly adjust your positioning. |
| Interact | E | Open/close doors, start treatment minigames, and pick up items; some tasks require holding E. |
| Break Free / Melee Attack | Mash E | Mash E repeatedly when grabbed by an enemy to break free; can also be used for melee attacks when unarmed. |
| Weapon Attack | Left Mouse Button M1 | Swing/shoot when holding a weapon, primarily reserved for wandering enemies like Skinwalker. |
| Photo | On-screen button | Clickable button on the interface, not bound to a specific key. |
| Shutter | On-screen button | The red reception button at the front desk; lower the shutter to reject suspicious patients. Like the photo button, this is clicked on-screen, not a keyboard key. |
Mobile/tablet play is confirmed, utilizing contextual touch buttons and supporting two-finger pinch-to-zoom to see details clearly. However, the developers have not yet released an official mobile key/layout map, and community descriptions have not been verified, so we do not provide precise mobile key bindings on this page—rely on the buttons that actually appear on your screen once you enter the game.
First, mash E to break free when grabbed; many newcomers forget this in a panic. Second, use M1 (Left Click) for weapons, while unarmed counterattacks follow standard interaction logic. Memorize these two points first.
Front Desk Screening: Admit or Shutter
The front desk is the most critical part of the game and where things go wrong most often. For every animal brought to the window, you must make a choice: admit them or lower the shutter to reject them.
Mixed in with the patients are Animal Anomaly—they disguise themselves as normal animals, but the details will give them away. Your job is like playing "spot the difference," checking if each patient is legitimate: look for inconsistencies in appearance, behavior, or registration info. If you judge them as a real patient, admit them; if you judge them as an Animal Anomaly, use the red shutter to block them out.
It must be emphasized that letting an Animal Anomaly in is like inviting a threat into the Animal Hospital; it will cause trouble inside and drain your Sanity. Of course, incorrectly rejecting a real patient isn't good either. Therefore, "look carefully before deciding" is always more important than "speed." For specific clues and how to check items, see our How to Spot an Anomaly page.
One of the biggest causes of death for beginners is "admitting a patient when you aren't sure." Please remember: if you are uncertain, do not admit them yet. Take a few more looks, check the details, and rather be a little slow than let a suspicious subject into the Animal Hospital. The shutter is your most important line of defense.
Eight Treatment Rooms: How to perform each procedure
After admission, patients must be sent to treatment rooms for mini-games to be cured. There are 8 treatment rooms in total, distributed across the left and right wings, each with different types of procedures. Check the overview table first, then look at the key points for each playstyle.
| Room | Location | Procedure Type | Gameplay and Key Points |
|---|---|---|---|
| Rooms 1–5 | Right Wing | DNA Treatment | Analyze the patient's DNA for about 10 seconds, then select the corresponding medication to treat them; choosing the wrong medication will kill the patient. |
| No. 6 | Left side | X-Ray | Sequence replication mini-game: Repeat the correct sequence as prompted |
| No. 7 | Left side | Heart Monitor | Click the white icons, avoid the skull marks, and fill the progress bar to 100% |
| No. 8 | Left side | Surgery | Timed use of scissors/scalpel; the timer starts the moment you interact |
DNA Treatment (Nos. 1–5)
Countermeasures：Wait patiently for the analysis results, match the result to the correct medication, and do not click randomly in a rush.
X-Ray (No. 6)
Countermeasures：Watch the entire prompt sequence before starting, then repeat it in the correct order.
Heart Monitor (No. 7)
Countermeasures：Only click white icons. If you see a skull, do not touch it; steadily push the progress bar to full.
Surgery (No. 8)
Countermeasures：Think through the steps before interacting, as the timer cannot be stopped once it starts; follow the mini-game instructions carefully.
First, in DNA treatment, choosing the wrong medication will directly kill the patient; be sure to wait until the analysis results align before acting. Second, if something like tentacles or tendrils appears during surgery, do not shoot it—it is part of the surgical procedure. Attacking it will only cause trouble; just focus on completing the time-limited scissors/scalpel mini-game.
Sanity management: Keep Sanity above 0
Sanity is the lifeline of your Shift. Unlike a health bar, it isn't restored through direct combat; it is gradually drained by the horror atmosphere, the anomaly, and various events.
The hidden failure condition for the entire run is Sanity reaching zero: once Sanity drops to 0, your Shift ends. This means that even if your screening and treatment are going well, you will still be "worn down" if you ignore your Sanity for too long. This is why many beginners find their "Shift ended" inexplicably, even though they weren't killed directly by a monster.
Treat Sanity as a resource that requires active maintenance: check its status frequently, and don't let it bottom out while you are focused on mini-games. Specific recovery methods, related items, and events that trigger Sanity loss can be planned in conjunction with the Supplies Shop.
Add "checking Sanity" to your loop: after screening one or two patients or completing a treatment, take a moment to check the Sanity bar. It is just as high a priority as "don't let the anomaly in."
Roaming enemies and sudden events
The Animal Hospital is not safe. In addition to the anomaly waiting in line at the window, roaming enemies will appear inside, and random events will trigger. This section provides a framework for beginners; see the Enemy Guide for details.
Anomaly patients
- Disguised as a normal animal
- Details/behavior reveal flaws
Countermeasures：Use the shutter at the reception to reject them; do not let them into the Animal Hospital.
Skinwalker
- Active inside the Animal Hospital
- Will actively pose a threat
Countermeasures：This is the primary target for your weapon (M1); save your ammunition for it.
Other wandering enemies and events
- Random appearance/trigger
- Various forms and mechanics
Countermeasures：Prioritize positioning and using the environment to resolve threats; do not blindly fight head-on; see the enemy bestiary for details.
Weapons and ammunition are limited; save them primarily for enemies like the Skinwalker that truly require force. Wasting bullets on minor nuisances leaves you defenseless when a real threat appears. Remember to mash E to break free when grabbed.
Night 1 Shift: Step-by-step walkthrough
Putting the knowledge above into practice, here is a recommended workflow for the "First Night" for complete beginners. Follow this to get a basic feel for the operations and rhythm of Animal Hospital.
- Familiarize yourself with the layout
Start by walking around with
WASD. Memorize the location of the reception window, the right wing (Rooms 1–5 for DNA), and the left wing (Rooms 6/7/8 for X-ray/Heart Rate/Surgery). If you see a red line above a room number, it means a patient is waiting inside. - Hold down the reception
Return to the window to receive the first batch of patients. Check each item against their appearance and behavior. Admit real patients, and use the shutter for any anomaly. If you are unsure, do not let them in.
- Treat patients and complete mini-games
Take admitted patients to their corresponding treatment rooms: for DNA, wait about 10 seconds for analysis then select the medicine matching the result; for X-ray, replicate the sequence; for Heart Rate, click the white icons while avoiding skulls to reach 100%; for Surgery, think before you interact (the timer starts immediately).
- Check your Sanity and surroundings constantly
After completing each task, look up to check your Sanity meter and scan for wandering enemies. Only consider using your weapon (
M1) if you spot a Skinwalker. - Stabilize the loop and survive the shift
Switch between screening, treating, and staying alive in small, quick steps; don't get greedy. If you can keep the loop stable and your Sanity above 0, you will successfully survive the first night and continue to the next shift.
Common beginner mistakes and corrections
These are pitfalls that almost every Animal Hospital beginner falls into. Knowing them in advance will save you from dying many times.
| Common mistake | Why it's bad | Correct approach |
|---|---|---|
| Letting them in when unsure | Once an anomaly enters the clinic, it creates threats and drains Sanity | When unsure, prioritize checking details; it is better to look twice than to admit them rashly |
| Ignoring the Sanity meter entirely | If Sanity hits zero, your shift ends immediately | Incorporate 'checking Sanity' into your routine; proactively use safe behaviors and items to stabilize it. |
| Wasting weapons on ordinary enemies. | Weapon ammo is limited; shooting recklessly will leave you defenseless against a real Skinwalker. | Save weapons primarily for the Skinwalker; handle ordinary nuisances through movement. |
| Shooting at the tentacles/tendrils during surgery. | That is part of the surgical procedure; attacking it will only cause trouble. | Follow the timed scissors/scalpel mini-game instructions carefully. |
| Rushing the DNA treatment and picking medicine randomly. | Choosing the wrong medicine will kill the patient instantly. | Wait about 10 seconds for the analysis results to appear, then administer the correct medicine. |
| Trying to handle the reception and treatment all by yourself. | Playing solo requires you to watch the window, run treatments, and fend off enemies simultaneously, which makes it very easy to get overwhelmed. | If possible, team up and divide the labor; assign roles for reception, treatment, and patrolling. |
Take it slow and steady: Observe before deciding, keep an eye on Sanity, and conserve your weapons; this will help you avoid 90% of common beginner deaths.
Solo or Co-op
Animal Hospital supports up to 30 players in co-op, but it is perfectly playable solo. The experience differs significantly between the two.
Solo: You must juggle reception screening, running treatments, monitoring Sanity, and dealing with roaming enemies alone. It is high-pressure with a low margin for error, but it is the best way to master the core loop and learn how to play Animal Hospital. Co-op: With more people, you can divide tasks—some can guard the reception and use the shutter, others can run the treatment room mini-games, and some can patrol for the Skinwalker and events. This significantly increases your resilience and creates a better horror co-op atmosphere.
| Dimension | Solo | Co-op (up to 30 players) |
|---|---|---|
| Division of Labor | Do it all yourself | Divide roles between reception, treatment, and patrol |
| Margin for Error | Low, easy to get overwhelmed | High, players can cover for each other |
| Learning Curve | Steep, but provides solid practice | Relaxed, good for watching how teammates handle things first |
| Atmosphere | Stronger sense of isolation and pressure | Cooperative communication, finding support in the tension |
Economy and Supplies: Animal Coins and Cash
While surviving your Shift, you will also interact with the game's economy system, used to purchase supplies to help you survive. This is just an introductory guide; for detailed prices and items, see the Supplies Shop.
The game features two types of resources—Animal Coins and Cash—as well as a Supplies Shop. You can use them to acquire items that increase your survival rate during your shift. This page does not list specific prices to avoid providing unverified numbers; when you are ready to dive into "what to buy and how to spend," please head to the Supplies Shop page to view the full list and pricing.
Don't rush to study the economy as a beginner. Prioritize mastering screening, treatment, and Sanity; resources will accumulate naturally. Once your basic loop is stable, it will be more cost-effective to shop for supplies as needed.

How to play Animal Hospital? Explained in one sentence
You are working the night shift at Animal Hospital: screen incoming animal patients at the front desk, admit the real ones, use the shutter to reject any anomaly disguised as an animal, and send admitted patients to the treatment rooms to be cured via mini-games. All the while, deal with wandering enemies and events, and keep your Sanity above 0. This is an endless mode where the goal is to survive as many shifts as possible.
I'm a complete beginner, what should I do on the first night?
First, use WASD to walk around and memorize the locations of the front desk and each treatment room. Then, return to the window to check patients one by one, carefully deciding whether to admit them or drop the shutter. Send patients to treatment to complete the corresponding mini-games, and keep an eye on your Sanity meter and surroundings at all times. For a detailed walkthrough, see "First Night Shift: Step-by-Step Guide" above.
How do I tell if a patient is an anomaly?
Anomalies disguise themselves as normal animals but reveal themselves through flaws in their appearance, behavior, or registration details. The gameplay is much like "spot the difference." When in doubt, it is better not to admit them. For a checklist of flaws to look for, see the How to Spot an Anomaly page.
What happens if I press the shutter button by mistake?
The shutter is the red rejection button at the front desk; lowering it rejects the patient. Letting an anomaly into Animal Hospital will cause internal threats and drain your Sanity; rejecting a real patient isn't good either. The core principle is "look carefully before deciding"; if you aren't sure, don't admit them.
What happens if my Sanity reaches zero?
Sanity is your hidden lifeline, constantly drained by the horror atmosphere, anomalies, and events. Once it reaches zero, your shift ends. Even if you aren't killed directly by a monster, ignoring your Sanity for too long will lead to a "breakdown," so treat monitoring your Sanity as just as important as screening patients.
What happens if I use the wrong medicine during treatment? Should I shoot the tentacles during surgery?
In the DNA treatment (1–5), choosing the wrong medicine will kill the patient, so be sure to wait about 10 seconds for the analysis results before administering it. In the surgery (8), if something like a tentacle or tendril appears, do not shoot it—it is part of the surgical procedure. Attacking it will only cause problems; you just need to complete the timed scissors/scalpel mini-game.
Who should I save my weapons for?
Weapons are fired with the left mouse button (M1), but ammo is limited. You should save it primarily for wandering enemies like the Skinwalker that actually require force. Don't waste bullets on minor nuisances. If grabbed by an enemy, mash E to break free. For more enemy info, see the Enemy Bestiary.
Can I play on a phone or tablet? What are the controls?
Yes. Mobile play is confirmed, using contextual touch buttons and supporting pinch-to-zoom. However, the developers have not yet released an official mobile button layout, and community descriptions vary, so this page does not provide precise mobile keybinds. Please rely on the buttons that actually appear on your screen once you enter the game.
Does the game have an ending? Are the shifts infinite?
There is no fixed ending; this is an endless mode: you face one shift after another, and the goal is to last as long as possible. The longer you persist, the more experience and resources you accumulate.
Can I play alone, or do I have to play in a team?
Both work. The game supports up to 30-player co-op. Solo play forces you to handle the front desk, treatment, and survival alone—it's high pressure but builds solid skills. Team play allows for role division (front desk/treatment/patrol), offering higher fault tolerance and a better atmosphere. Beginners are advised to observe in a team before trying solo.
What are the basic PC controls?
WASD to move, Space to jump, E to interact (some tasks require holding, mash to break free when grabbed, also used for melee counter-attacks), M1 (Left Click) for weapon attacks. Photo and Shutter are on-screen buttons, not keyboard shortcuts, so don't look for them in the keybinds.
Where do I buy items and supplies?
There is an in-game Supplies Shop where you can use Animal Coins and Cash to purchase items that improve your survival rate. Beginners are advised to master the core loop and accumulate resources naturally before purchasing as needed. For a complete list of prices and items, see the Items & Supplies Shop.
