All Animal Hospital Classes — Complete List & Guide

All Classes in Animal Hospital

Classes are unlockable roles in Animal Hospital that provide passive bonuses during shifts. Every player starts as Intern for free. Classes are purchased in the lobby Class Shop using Animal Coins (earned in-game) or Robux (premium currency).

Each class can be upgraded through 3 levels, with each level adding stronger effects.

Quick Comparison Table

Best Free Class: Surgeon

Surgeon (2,500 Animal Coins) is the strongest earnable class. Every heal grants Sanity recovery AND a speed boost. At Level 3, it doubles Sanity gain — making you nearly invincible during shifts.

Best Paid Class: Secret Agent

Secret Agent (Robux) starts with a Gun, the most powerful anomaly weapon. At Level 3, the gun regenerates 1 use per round, effectively giving unlimited shots.

Recommended Progression Path

1. Start as Intern (free)
2. Save for Doctor (900 coins) — first Sanity-recovery class
3. Upgrade to Surgeon (2,500 coins) — best self-sustaining build
4. Optional: Buy Secret Agent (Robux) for maximum anomaly firepower

How to Unlock Classes in Animal Hospital

Unlocking classes follows a universal process regardless of which class you want. Here is the complete walkthrough:

Step 1: Earn Animal Coins (for coin-based classes)

Animal Coins are earned by completing shifts. Your reward per shift depends on:

• Correct anomaly identifications — Each correct call earns bonus coins.
• Patient survival rate — Keeping more patients alive increases your payout.
• Shift completion — Simply finishing a shift without disconnecting guarantees a base reward.
• Difficulty bonus — Later shifts with more anomalies pay higher coin rewards.

A typical early-game shift earns 3–5 coins. Mid-game shifts (shifts 8–12) can yield 6–10 coins. Late-game shifts (shifts 15+) may reward 8–15 coins. To unlock the Surgeon (2,500 coins), expect to play roughly 250–400 shifts total, or about 20–40 hours of gameplay.

Step 2: Purchase Robux (for premium classes)

Premium classes — Head Nurse and Secret Agent — require Robux, which is Roblox's real-money currency. Robux can be purchased through:

• The Roblox website (roblox.com) on the Robux purchase page.
• The Roblox mobile app on iOS or Android.
• Gift cards available at retail stores like Walmart, Target, and GameStop.

Robux prices vary by region and bundle size. Check the Roblox website for current pricing.

Step 3: Open the Class Shop

From the Animal Hospital lobby, navigate to the Class Shop. It is typically located near the main desk or reception area. You can interact with the Class Shop NPC directly or open the class selection menu from your HUD.

Step 4: Select and Purchase Your Class

Browse the class cards in the shop. Each card displays the class name, cost, currency type, and a preview of the core ability. Click on the class you want and confirm the purchase. The currency (Animal Coins or Robux) will be deducted from your balance immediately.

Step 5: Equip and Play

Purchased classes appear in your owned classes list. Select any owned class and equip it before entering a shift. You can switch classes between shifts at no additional cost. There is no limit to how many classes you can own.

Detailed Class Breakdown by Tier

S Tier Classes

Surgeon — The gold standard for earnable classes. Sanity recovery + speed on every heal makes it the most self-sufficient class in the game. At Level 3, doubled Sanity gain means you can survive the hardest shifts without external support. The 2,500 coin price tag is steep but absolutely worth it.

Secret Agent — The strongest class in the game if you are willing to spend Robux. The anomaly Gun is the most powerful weapon available, capable of neutralizing threats that other classes can only run from. At Level 3, gun regeneration means infinite firepower. The Secret Agent trivializes anomaly encounters but costs premium currency.

A Tier Classes

Psychologist — The Sanity specialist. Doubled Sanity effects from all sources means sanity-restoring items work twice as well, and any Sanity recovery from teammates is also doubled. At 500 coins, the Psychologist is one of the best value classes in the game, especially for team play where your doubled Sanity effects benefit the entire squad.

Doctor — The first Sanity-recovery class most players unlock. Healing patients restores Sanity, creating a self-sustaining loop where treating patients keeps you alive longer. At 900 coins, the Doctor is affordable within 15–20 hours of gameplay and serves as an excellent bridge between the Intern and the Surgeon.

B Tier Classes

Secretary — Sanity recovery on patient check-in is a passive, reliable source of Sanity that requires no additional effort beyond your normal screening duties. At 120 coins, it is very affordable and provides meaningful survivability improvement over the Intern.

Security — The X-Taser gives you a direct offensive tool against anomalies, something most classes lack. At 1,250 coins it is expensive, but the ability to stun or neutralize anomalies rather than just running from them is uniquely valuable. The 5 uses at Level 1 demand careful resource management.

Head Nurse — Inventory expansion and item generation make this the best support utility class. Its Robux cost drops it to B Tier for free-to-play players, but in a team setting it performs at S Tier. See our Head Nurse guide for full details.

C Tier Classes

Paramedic — Speed is useful but does not address the game's core Sanity mechanic. The Large Speed Cola enables fast play but leaves you dependent on teammates or items for Sanity management. See our Paramedic guide for full details.

Nurse — The cheapest unlockable class, but a single inventory slot provides almost no practical advantage. Loses the Intern's +10 Sanity passive for minimal benefit. See our Nurse guide for full details.

D Tier Classes

Intern — The free starter class. The +10 Bonus Sanity is actually useful for new players learning the game, but the Intern has no utility beyond that passive. Everyone starts here, and everyone should leave as soon as possible.

Frequently Asked Questions

What is the best class in Animal Hospital?

The Surgeon is the best earnable class (2,500 Animal Coins) and the Secret Agent is the best overall class (Robux). The Surgeon provides Sanity recovery and speed on every heal, making it self-sustaining. The Secret Agent has a powerful anomaly Gun that can neutralize threats. For free-to-play players, Surgeon is the ultimate goal.

Can I use multiple classes at once?

No. You can only equip one class at a time per shift. However, you can switch classes between shifts at no cost. In multiplayer, different players can each equip different classes, allowing your team to combine multiple class benefits simultaneously.

How do I earn Animal Coins fast?

The fastest way to earn Animal Coins is to complete shifts with high performance: correctly identify anomalies, keep patients alive, and finish shifts without disconnecting. Later shifts pay more coins due to increased difficulty. Playing with a coordinated team also improves efficiency, letting you complete more shifts per hour.

Are premium classes (Robux) worth it?

It depends on your budget and playstyle. The Secret Agent is the strongest class in the game and provides a fundamentally different experience with anomaly-fighting capability. The Head Nurse is an excellent support class for team play. If you play Animal Hospital regularly and can afford the Robux cost, both premium classes provide meaningful advantages. If you prefer not to spend real money, the Surgeon (2,500 coins) is the best free alternative.

Can class abilities stack with teammates?

No, class abilities are individual and do not stack across players. A team with two Doctors does not get double Sanity recovery — each Doctor heals independently. However, the effects are additive in practice since two Doctors can heal twice as many patients, covering more of the team's Sanity needs.

What happens to my class if I die or disconnect during a shift?

Your equipped class remains active for the remainder of that shift (even if you die, the passive bonuses may still apply to your character state). If you disconnect, you lose progress for that shift but your class selection persists. Between shifts, you can freely change classes regardless of what happened in the previous shift.
