Classes are the role you equip before a shift in Animal Hospital. Some start with extra sanity, some hand you a taser or speed cola, and a couple are Robux-only power picks. You buy them in the yellow Classes circle by the lobby ambulance, then upgrade each one through three perk levels as you play.

How class unlocks work
Walk into the yellow Classes marker left of lobby spawn (next to the ambulance). Coin classes spend Animal Coins; premium classes spend Robux. After you buy one, open the Classes button on the left menu and equip it before the shift starts. The equipped name sits above your avatar in the lobby and beside your sanity bar once the hospital loads.
Every class has three upgrade levels. Higher levels do not invent a new kit; they stretch the same idea with bigger sanity pads, more inventory, stronger starter uses, or a small regen on the starter item.
What to buy first with Animal Coins
Coins are slow early, so spend in order of real impact:
- Nurse is the cheap first upgrade. Extra inventory slots mean fewer trips between the desk, rooms, and supply machines.
- Secretary or Paramedic next, depending on whether you live at check-in or you chase fires and faints across the map.
- Security when threats start winning fights. A multi-use X-Taser beats running back to the shop box mid-crisis.
- Surgeon is the long-term coin goal. Healing pays you sanity and a speed burst, so treatment loops stay smooth in solo and team runs.
Skip dumping coins into pure sanity padding (Doctor-style) until your main loop already feels stable. Sanity recovery is useful, but inventory, mobility, and threat control usually save more shifts.
Sanity classes vs starter-item classes
Sanity specialists (Doctor, Psychologist, Surgeon) reward the work you already do. Doctor and Surgeon top you up when you finish heals; Psychologist doubles every sanity gain and loss, so coffee and clean play feel great while random hits hurt twice as hard.
Combat and utility classes skip the passive grind and hand you tools. Paramedic opens with Large Speed Cola for map coverage. Security opens with an X-Taser for shapeshifters and bad admits. If your team already has a desk main, one combat class often does more than a second sanity stacker.
Premium classes
Head Nurse is the Robux support pick: big inventory right away, then bonus sanity and Special Technique utility as you upgrade. Secret Agent is the Robux combat pick: a loaded gun that makes ghosts, shapeshifters, and other hostiles much less scary.
Robux prices move between patches and guides. Always read the number in the live class shop before you buy. Coin prices for the free-to-play ladder are much more stable.
Common mistakes
- Staying on Intern after you understand check-in. Free bonus sanity is training wheels, not a late-game plan.
- Buying Psychologist too early. Doubled losses punish messy shifts harder than doubled gains help.
- Ignoring upgrades on a class you already like. Level 3 often adds use regen on starter items or a bigger sanity pad that changes how long the kit lasts.
- Treating skins as upgrades. Class skins are cosmetic only; they do not change perks.
FAQ
How do you unlock classes in Animal Hospital?
Enter the yellow Classes circle in the lobby (left of spawn, next to the ambulance) and buy with Animal Coins or Robux. Equip the class from the Classes menu before your next shift.
Can you upgrade classes in Animal Hospital?
Yes. Every class has three levels. Upgrades improve the same perk idea: more sanity, more inventory, stronger starter uses, or small extras like use regen each round.
What is the best beginner class?
Start on Intern for free bonus sanity while you learn check-ins and treatments. As soon as you can, buy Nurse for inventory space, then pick Secretary for desk work or Paramedic if you chase emergencies.
What is the best free-to-play class to save for?
Surgeon is the strongest long-term Animal Coins spend for active healers. Security is the better mid-game buy if your shifts die to hostiles more than to slow treatment loops.
Are Head Nurse and Secret Agent worth Robux?
Head Nurse is the flexible support spend if you want inventory and later-round utility without grinding coins. Secret Agent is the combat spend if you want a gun for anomalies and monsters. Check the current Robux price in the shop, because guides disagree on the exact numbers.
Do class skins change your perks?
No. Skins are cosmetic only. Your equipped class and its upgrade level set the real bonuses.
