Intern
WeakestFree N/A
+10 to +20 bonus sanity at shift start
The default class every player starts with. Gives bonus starting sanity — a small safety buffer for learning the ropes. Upgrade to a real class as soon as you can afford it.
| Level | Effect |
|---|---|
| 1 | +10 bonus sanity at shift start |
| 2 | +15 bonus sanity at shift start |
| 3 | +20 bonus sanity at shift start |
Available Skins
Nurse
Beginner Classes10 Animal Coins
+1 to +3 inventory capacity
The best budget class in the game. At just 10 Animal Coins, you get extra inventory capacity that reduces trips between rooms. Excellent value for F2P players.
| Level | Effect |
|---|---|
| 1 | +1 inventory slot |
| 2 | +2 inventory slots |
| 3 | +3 inventory slots |
Available Skins
Paramedic
Weakest250 Animal Coins
Start with Run Fast Cola (6-9 uses)
A niche pick focused on movement speed. The Run Fast Cola helps you zip around the hospital, but the lack of meaningful utility makes it hard to recommend over other options.
| Level | Effect |
|---|---|
| 1 | Start with Run Fast Cola (6 uses) |
| 2 | Start with Run Fast Cola (9 uses) |
| 3 | Start with Run Fast Cola (9 uses), regenerate 1 use each round |
Secretary
Sanity Classes120 Animal Coins
Recover sanity when checking in patients
A budget-friendly sanity management class. Each patient you check in at the front desk restores a small amount of sanity. Great for learning the sanity mechanics without pressure. Note: Secretary's species changed from Bunny to Sheep in Harlow's Update.
| Level | Effect |
|---|---|
| 1 | Recover 1 sanity per check-in |
| 2 | Recover 1 sanity per check-in, +5 bonus sanity |
| 3 | Recover 1 sanity per check-in, +10 bonus sanity |
Available Skins
Psychologist
Sanity Classes500 Animal Coins
Double all sanity effects, chance to ignore sanity loss
A high-risk, high-reward class for expert players. All sanity gains and losses are doubled. At higher levels, a chance to ignore sanity loss provides a safety net. One mistake can still cost you the run.
| Level | Effect |
|---|---|
| 1 | All sanity effects doubled (positive and negative) |
| 2 | All sanity effects doubled, 7.5% chance to ignore sanity loss |
| 3 | All sanity effects doubled, 15% chance to ignore sanity loss |
Available Skins
Doctor
Sanity Classes900 Animal Coins
Recover sanity when healing patients
A solid mid-tier class that pays for itself through sanity recovery. The bonus sanity cap at Level 2 makes it easier to survive longer shifts. A stepping stone to Surgeon.
| Level | Effect |
|---|---|
| 1 | Recover 1 sanity per patient healed |
| 2 | Recover 1 sanity per patient healed, +15 bonus sanity |
| 3 | Recover 1 sanity per patient healed, +20 bonus sanity |
Security
Beginner Classes1,250 Animal Coins
Start with X-Taser and Deployable Camera (L2+)
The go-to class for combat-focused players. Reworked in Harlow's Update — now gains a Deployable Camera at Level 2. The X-Taser stuns anomalies and the camera provides portable CCTV coverage.
| Level | Effect |
|---|---|
| 1 | Start with X-Taser (5 uses) |
| 2 | Start with X-Taser (6 uses) + Deployable Camera |
| 3 | Start with X-Taser (6 uses) + Deployable Camera, regenerate 1 use each round |
Surgeon
Best Classes2,500 Animal Coins
Gain sanity and speed boost after healing patients
The best F2P class in Animal Hospital. Every patient you heal restores sanity and gives a speed boost. At Level 3, you become a healing machine with double sanity returns. Worth every Animal Coin. Note: Surgeon's species changed from Deer to Moose in Harlow's Update.
| Level | Effect |
|---|---|
| 1 | Restore sanity + short speed boost per heal |
| 2 | Restore sanity + 8s speed boost per heal |
| 3 | 2x sanity gain + 8s speed boost + 10 bonus sanity |
Head Nurse
Best Classes80 Robux
Increased inventory capacity + bonus sanity
The premium inventory class. Level 2 adds bonus sanity. At Level 3, you start every shift with one of every basic item. Reduces trips to the shop dramatically and keeps the team supplied.
| Level | Effect |
|---|---|
| 1 | +3 inventory slots |
| 2 | +3 inventory slots, +10 bonus sanity |
| 3 | +3 inventory slots, start each round with all items |
Available Skins
Secret Agent
Very Good320 Robux
Start with a Gun and Scanner
The premium combat class. Reworked in Harlow's Update — now starts with a Scanner at Level 1 alongside the Gun. Packing heat and detection gear from the start makes you self-sufficient. Level 3 turns combat into a profit engine.
| Level | Effect |
|---|---|
| 1 | Start with Gun (20 uses) + Scanner, +2 carry capacity |
| 2 | Start with Gun (24 uses), +1 use each round |
| 3 | Killing anomalies grants +4 sanity and +$5 cash, Gun regenerates |
Available Skins
Firefighter
Beginner Classes1,100 Animal Coins
Start with a rechargeable Fire Extinguisher, +1 max inventory
Added in The Hazmat Team Arrives update. The Firefighter starts each shift with a rechargeable Fire Extinguisher and an extra inventory slot. At Level 2, putting out fires restores sanity. At Level 3, you become immune to fire damage entirely with a generous sanity buffer — perfect for handling slime shifts and fire emergencies.
| Level | Effect |
|---|---|
| 1 | Start with Fire Extinguisher +1 max inventory |
| 2 | Recover 1 sanity when extinguishing fires |
| 3 | Fire immunity, +10 bonus sanity, +1 max inventory |
Which Class Should You Pick?
F2P (Free-to-Play)
Start with Nurse (10 Animal Coins). It is cheap and the extra inventory helps enormously. Next, grab Firefighter (1,100 Animal Coins) for fire immunity and utility, then save toward Surgeon (2,500 Animal Coins), the best F2P endgame class. If you need sanity support, Doctor (900 Animal Coins) is a solid mid-tier pick.
Robux
If you are willing to spend Robux, Head Nurse (80 Robux) provides incredible team utility with its massive inventory. Secret Agent (320 Robux) is the best solo class, letting you handle anomalies with ease right from shift 1.
