Classes shape how every night shift plays out in Animal Hospital, the anomaly horror experience on Roblox where you check in patients, treat the real animals, and weed out the things pretending to be animals. Each class hands you one passive perk, and most of those perks revolve around Sanity, the meter that keeps you in the game. Let your Sanity hit zero after a jumpscare or a botched treatment and you trigger the bad ending, so the right class can be the difference between finishing a shift and washing out early.
Quick answer: There are 10 classes. Intern is free and equipped by default, every other Animal Coin class is bought from the Class Shop in the lobby, and two classes (Head Nurse and Secret Agent) cost Robux. Surgeon is the strongest pick you can buy with Animal Coins.
How to buy and equip classes in Animal Hospital
Classes live in the Class Shop, found on the left side of the server lobby near the ambulance. There are no quests or unlock conditions beyond having enough currency. Animal Coins come from completing shifts, with Shift 1 paying out five coins for treating a couple of patients, and later shifts paying more as you treat patients, spot anomalies, and keep your Sanity topped up. Robux classes skip the grind entirely.
You cannot switch classes once a shift has started, so confirm the right one is equipped before you join a round. Buying a class only grants its perk for now, though developer notes confirm class skins that change your in-game model are planned for a future update.

Note: The Robux prices for Head Nurse and Secret Agent have shifted between updates, so the in-game shop is the only place to confirm the exact cost before you buy. Head Nurse has been listed at 80 Robux and 140 Robux, while Secret Agent has appeared at 320 Robux and 790 Robux.
What each perk does on a shift
The perks split into four jobs: padding Sanity, carrying more items, moving faster, and fighting back against anomalies. Knowing which bucket a class falls into makes it easier to match a class to how you actually play.
- Sanity perks: Intern front-loads +10 Sanity, Secretary recovers 1 per check-in, Doctor recovers 1 per heal, and Psychologist doubles every Sanity change in both directions.
- Inventory perks: Nurse adds one slot, Head Nurse adds three, which cuts down trips between the office, patient rooms, and the supply machines.
- Speed perks: Paramedic spawns with a Large Speed Cola good for six drinks, and Surgeon grants both Sanity and a short speed boost after each heal.
- Combat perks: Security starts with an X-Taser (5 uses) to stun anomalies or crazed patients, while Secret Agent starts with a gun (20 uses) that can eliminate threats outright.
Psychologist is the one perk that cuts both ways. Doubling positive Sanity makes recovery much stronger, but doubling negative Sanity means a single bad scare or a slow treatment drains you twice as fast, so it suits players who already manage the meter well.
Best classes to buy first
For free-to-play players, Surgeon is the long-term goal among the Animal Coin classes. Healing patients is the core objective anyway, and Surgeon rewards every heal with both Sanity and movement speed, which makes solo runs far less stressful than relying on Doctor’s Sanity-only version.
Early on, Nurse is the cheapest worthwhile buy at 10 Animal Coins, and the extra inventory slot helps in nearly every shift, especially in team runs where multiple Nurses stack carrying space. Paramedic is the pick if you mainly want speed, though the same buff is available from the Speed Boost Cola in the Supplies Shop, so weigh that before spending coins.
If you are spending Robux, Head Nurse gives the largest inventory boost in the game with +3 slots and works equally well solo or in a group. Secret Agent is the most aggressive option, since starting every shift armed lets you deal with anomalies on sight instead of scrambling for items mid-round.
More classes are planned for upcoming updates, so the lineup of 10 is likely to grow as the class system expands.
