Ranked guide
Animal Hospital Tier List
Use this page to compare Animal Hospital anomaly danger and the best classes for Roblox shifts. Anomaly rankings focus on detection difficulty and time pressure during check-in, CCTV, and photo screening — hostile threats encountered during patient treatment are listed separately below. Class rankings focus on sanity, utility, starter items, and team value.
Best classes
Animal Hospital Best Classes Tier List
Pick classes around the job your squad is missing. Treatment-heavy teams benefit from Surgeon, Doctor, and Nurse-style routing, while dangerous shifts are easier when Security or Secret Agent can answer threats.
S
Best overall value for coordinated shifts, either by improving treatment flow or answering threats.
Head Nurse
High inventory value for carrying treatment items and keeping rooms prepared.
Secret Agent
Expensive Robux class, but the gun gives direct answers to dangerous monsters.
A
Reliable role picks when your team needs sanity sustain, front-desk coverage, or defensive utility.
Doctor
Good patient-focused role with sanity recovery tied to healing.
Psychologist
High-risk sanity specialist because positive and negative sanity effects are amplified.
Security
Starts with an X-Taser, making Ghost and monster response more consistent.
B
Useful starter and support options, but usually less complete than the higher tiers.
Secretary
Fits front-desk screening and can regain sanity while checking in patients.
Nurse
Simple support class with extra inventory capacity for treatment item delivery.
Paramedic
Speed-cola utility helps movement, especially once uses can regenerate.
C
Fine for learning the game, but quickly replaced after earning coins.
Intern
Free starting class with bonus sanity but no team utility or starter item.
Anomaly danger
Animal Hospital Anomaly Danger Tier List
This first version ranks entries by expected detection difficulty and shift pressure. Treat unverified entries as placeholders until they are confirmed through gameplay or reliable community evidence.
S
Run-ending pressure, immediate counter item needed, or severe sanity risk.
A
Easy to miss during a busy shift, often requiring CCTV, photo checks, or small-detail inspection.
B
Solvable with a routine check, but still costs time and attention.
C
Obvious visual tells that are good for beginner training.
Special
Quest or NPC route rather than a normal danger ranking.
Wildlife threats
In-Game Hostile Anomalies
These threats are encountered during patient treatment rather than at check-in or CCTV screening. They are confirmed from gameplay footage, but not yet assigned a formal danger ranking on this tier list.
Bed Monster
Black figure with round red eyes under patient beds. Step in its red zone and it grabs you. Give it Maple Syrup to pacify it.
Stalker
Extremely tall black bunny with a toothy smile. Looking directly at it costs 10 sanity. Avoid eye contact when passing.
Don't Look Up
Mass of eyeballs and flesh on the ceiling in patient rooms or the CCTV room. Looking up drains sanity rapidly.
Wall Anomalies
Groups of 2–5 figures that chase you if approached directly. Deal sanity damage and can steal items from your inventory.
Skin Walkers
Created when infected patients slip through check-in. Sharp teeth and wide mouths. Attack players and patients. Press E to break free if grabbed.
Headbanger
Patient at the check-in window smashing their head on the glass. Give it Coffee to neutralize. Ignoring it cracks the window.
Surgery Tentacles
Purple tentacles erupt in Room 8 with a 45-second surgery timer. Using a taser or gun instantly kills the patient.
Hiders
Camouflaged monsters that hide against windows, curtains, and walls. Getting too close triggers an attack. Listen for loud breathing and scan for their eyes and grin. Usually appear in groups of three.
