Roblox Animal Hospital classes guide

Choosing the right Animal Hospital class (Anomaly) can make surviving longer shifts significantly easier. While every player can inspect patients, treat animals, and stop anomalies, each class provides unique passive bonuses that support different playstyles.

Some classes focus on Sanity management, others improve inventory space, while premium options provide exclusive equipment like a Gun or Taser at the start of every run.

This guide covers every currently available Animal Hospital class, how each one works, which players should use them, and which classes are worth unlocking first.

How do classes work in Animal Hospital?

Classes are permanent loadouts that grant passive bonuses throughout every shift.

Unlike traditional RPGs, they don't lock you into specific roles. A Doctor can still inspect patients, while a Secretary can still treat them. Instead, each class rewards a certain playstyle by improving specific mechanics like:

• Sanity recovery
• Starting equipment
• Inventory size
• Movement speed
• Starting cash
• Utility

Most classes can be purchased using Animal Coins, while several premium classes require Robux. Many classes also become noticeably stronger after reaching Level 3, unlocking improved passives or additional bonuses.

All Animal Hospital classes

Every Animal Hospital class explained

Let’s take a closer look.

Intern

The Intern is the default class every player begins with.

It has no unique gameplay mechanic but starts with additional Sanity that increases as the class levels up.

Level bonuses

• Level 1: +10 Sanity
• Level 2: +15 Sanity
• Level 3: +20 Sanity

Best for

• New players
• Learning anomaly detection
• First few shifts

Because it doesn't introduce additional mechanics, Intern is an excellent learning class before investing Animal Coins elsewhere.

Nurse

Cost: 20 Animal Coins

The Nurse increases your maximum inventory size.

Bonuses

• Level 1: +1 inventory slot
• Level 2: +2 inventory slots
• Level 3: +3 inventory slots

If your team frequently carries medicine, coffee, tools, or emergency supplies, Nurse offers consistent quality-of-life improvements without changing gameplay dramatically.

Secretary

Cost: 120 Animal Coins

Secretary specializes in checking patients into the hospital.

Every successful patient admission restores Sanity, making this one of the strongest economy-focused classes for reception players.

Bonuses

Recover 1 Sanity whenever checking in a patient

• Level 2: +5 bonus Sanity
• Level 3: +10 bonus Sanity
• Starts with $20

During long shifts with heavy patient traffic, the steady Sanity recovery can offset many passive Sanity losses.

Best for

• Reception
• Solo progression
• Long shifts

Paramedic

Cost: 250 Animal Coins

Paramedic starts each run with a Large Speed Cola, allowing faster movement around the hospital.

Bonuses

• Level 1: Speed Cola (6 uses)
• Level 2: Speed Cola (9 uses)
• Level 3: Speed Cola regenerates one use each round

The movement boost lasts around two minutes per use, making this class useful for players constantly travelling between treatment rooms.

Psychologist

Cost: 500 Animal Coins

Psychologist completely changes how Sanity works.

Every Sanity effect is doubled.

That means:

• Bigger Sanity gains
• Bigger Sanity losses

Additional bonuses

• Starts with full Sanity
• Level 2: 7.5% chance to ignore Sanity loss
• Level 3: 15% chance to ignore Sanity loss

This Animal Hospital class rewards experienced players who understand when they'll lose or recover Sanity during a shift.

Doctor

Cost: 900 Animal Coins

Animal Hospital Doctor is one of the strongest support classes.

Healing patients restores Sanity, encouraging players to stay focused on medical treatment.

Bonuses

• Gain 1 Sanity after healing patients
• +10 bonus Sanity
• Level scaling increases bonus Sanity

In multiplayer, assigning one player as a dedicated Doctor helps maintain both patient flow and Sanity throughout longer shifts.

Security

Cost: 1,250 Animal Coins

Security begins every shift with a Taser, allowing players to deal with nearby threats immediately.

Bonuses

• Level 1: Taser (5 uses)
• Level 2: Taser (6 uses)
• Level 3: Regenerates one charge each round
• Starts with $20

The Taser should primarily be used against anomalies rather than ordinary patients.

Head Nurse

Premium (Robux)

Head Nurse is a premium inventory-focused class.

Bonuses

• +3 inventory slots
• Level 2: +10 bonus Sanity
• Level 3: Starts each round with a Special Technique Upgrade

This Animal Hospital class is aimed at players who frequently carry multiple supplies during long multiplayer sessions.

Surgeon

Cost: 2,500 Animal Coins

Surgeon expands on the Doctor's playstyle.

Instead of only restoring Sanity, healing patients also grants a temporary movement speed boost.

Bonuses

• Heal patient → gain Sanity
• Heal patient → short speed boost
• Level 3:
  • Double Sanity recovery
  • 8-second speed boost
  • +10 bonus Sanity

Surgeon is one of the strongest late-game Animal Hospital classes thanks to its ability to reward continuous patient treatment.

Secret Agent

Premium (Robux)

Secret Agent starts every shift with a Gun instead of requiring players to purchase one.

Bonuses

• Gun (20 uses)
• Starts with $50
• Level 2:
  • Gun (30 uses)
  • +10 bonus Sanity
• Level 3:
  • Gun regenerates one shot per round
  • +20 bonus Sanity

The Gun provides ranged protection against certain threats, reducing the need to approach anomalies at close range. The transcript also notes that some anomaly types cannot be damaged with it, so positioning still matters.

Best Animal Hospital classes ranked

Which Animal Hospital class should you unlock first?

If you're spending Animal Coins efficiently, this progression offers the best value:

• Secretary
• Doctor
• Security
• Surgeon
• Psychologist

Secretary provides immediate value during every shift, while Doctor and Surgeon become increasingly powerful once you're consistently treating patients. However, every class in Animal Hospital fills a different niche rather than replacing another outright.
