Animal Hospital Wiki — Survival Guide
Complete fan wiki for Roblox Animal Hospital: anomaly list, patient roster, beginner tips, tier list, and the latest codes.
What is Animal Hospital (Anomaly)?
You got hired to work the night shift at an animal hospital. Cartoon animal patients arrive in the waiting room and it is your job — as the antlered doctor with the stethoscope and scalpel — to treat them. The catch: some patients are not what they seem. They are anomalies, corrupted versions of the normal animals, and treating one like a regular patient is a mistake.

Doctor roles: treat or report
Treating patients
- Greet each patient and scan their appearance against the normal patient roster.
- Treat standard injuries — bandages, crutches, visible ailments — through the normal treatment flow.
- Stay methodical. Rushing a real patient is how you misread what you are looking at.
Identifying anomalies
- Watch for mismatched faces, all-black bodies, or patients standing where they should be seated.
- Compare every patient against the anomaly list before treating — a half-second check beats a wrong call.
- Do not treat an anomaly. Use the report/anomaly-handling action instead.

Frequently asked questions
What is Animal Hospital (Anomaly) on Roblox?
It is a survival/anomaly-horror game where you work the night shift as a doctor at an animal hospital. You treat cartoon animal patients, but some patients are anomalies that behave abnormally and must be identified instead of treated. The game mixes cozy clinic roleplay with tension from spotting impostors among your patients.
How do I tell an anomaly from a normal patient?
Use the 4-layer detection system: Visual (does the patient look normal?), Photo (does the clipboard photo match?), CCTV (does the camera feed look normal?), and Document (does the patient file match?). A fail on any single layer means reject. Only treat when ALL layers pass. Common tell signs include mismatched faces, all-black bodies, three eyes, sharp teeth, and patients standing where they should be seated.
What happens if I treat an anomaly by mistake?
Treating an anomaly instead of rejecting it drains your sanity and can cause the anomaly to escalate into a Skinwalker — one of the deadliest threats in the game. Repeated mistakes compound: low sanity impairs your vision and judgment, making further mistakes more likely.
Are there any Animal Hospital codes right now?
As of the latest check there are no active redeemable codes from the developer Animal Anomaly. The game launched in May 2026 and has not yet added a code redemption system. Our codes page is updated as soon as codes are released.
What is the best strategy for beginners?
Start as the free Intern class, learn the normal patient roster first (so corrupted versions stand out), buy Coffee as your first shop item for sanity management, and run the full 4-layer check on every single patient before treating. Never rush — speed is what causes misreads.
Can I play Animal Hospital with friends?
Yes, each server supports up to 30 players. Coordinating with teammates — one person on CCTV monitoring, one on admission window checking patients, one on treatment — makes higher shifts significantly easier. Solo play is viable through Shift 6, but Shift 7+ is designed for teams.
Is Animal Hospital free to play?
Yes, the game is completely free on Roblox. No codes or Robux are required to start playing. The Intern class is free, and you earn Cash by completing shifts to unlock better classes. Two premium classes (Head Nurse, Secret Agent) require Robux purchase.
Is Animal Hospital available on mobile, console, or Android?
The game is available on any platform that supports Roblox: PC, Mac, iOS, Android, Xbox, and PlayStation. Search "Animal Hospital" on the Roblox app for your device.
