Choosing the right class in Animal Hospital Anomaly can make surviving later shifts much easier. Some classes focus on managing sanity, while others give speed boosts or provide useful items. However, not every class is worth spending your Cat Coins or Robux on. If you’re wondering which classes deserve your money, here’s a complete tier list and explanation of every class currently available.
Animal Hospital Anomaly Class Tier List
S Tier
- Surgeon
- Paramedic
A Tier
- Doctor
- Secretary
B Tier
- Intern
- Psychologist
C Tier
- Nurse
- Security
D Tier
- Head Nurse
- Secret Agent
Intern (Starter Class)
Cost: Free
Intern is the default class that everyone starts with. Its passive effect gives you an additional 10 sanity at the beginning of a game, increasing your starting sanity to 75. While the effect isn’t amazing, it’s free and provides a small advantage for beginners. Since you don’t need to spend any Cat Coins, it’s a decent starter option.
Tier: B
Nurse
Cost: 20 Cat Coins
Nurse grants one extra inventory slot, allowing you to carry an additional item. Although the price is cheap, inventory space usually isn’t a problem in Animal Hospital Anomaly. Most players don’t need many items at once, making this class difficult to recommend.
Tier: C
Secretary
Cost: 120 Cat Coins
Secretary restores one sanity point every time you check in a patient. This may seem small, but over the course of a shift, those extra sanity points add up. It helps you stay mentally stable without constantly relying on coffee or chocolate. Because it’s affordable and useful, Secretary is one of the best early-game classes.
Tier: A
Paramedic
Cost: 250 Cat Coins
Paramedic gives you Speed Cola, which can be used six times to temporarily increase movement speed. The speed boost is incredibly useful when:
- Treating multiple critical patients.
- Putting out fires.
- Interrupting rituals.
- Chasing anomalies.
- Handling emergencies quickly.
Its versatility makes Paramedic one of the strongest classes in the game.
Tier: S
Psychologist
Cost: 500 Cat Coins
Psychologist doubles all sanity effects.
This means:
Advantages
- Coffee restores more sanity.
- Chocolate becomes more effective.
Disadvantages
- Rituals drain more sanity.
- Stress events become more dangerous.
- Certain anomaly attacks hurt your sanity twice as much.
Since the benefits and drawbacks balance each other out, this class doesn’t provide much value compared to other options.
Tier: B
Doctor
Cost: 900 Cat Coins
Doctor restores one sanity every time you heal a patient.
Players who focus on treating patients will gain plenty of sanity throughout the game, making it easier to handle stressful events and anomalies without worrying about running out of sanity.
Doctor works especially well in multiplayer teams where you’re assigned as the primary healer.
Tier: A
Security
Cost: 1,250 Cat Coins
Security starts with an X-Taser that has five uses.
While having a taser early is nice, the game eventually gives players access to regular tasers after a few shifts. Because of that, spending over a thousand Cat Coins on this class isn’t very efficient.
Tier: C
Head Nurse
Cost: 80 Robux
Head Nurse provides three additional inventory slots.
Although carrying more items sounds useful, inventory management rarely becomes a major issue. Most players won’t benefit enough to justify spending Robux.
Tier: D
Surgeon
Cost: 2,500 Cat Coins
Surgeon is one of the best late-game classes.
Whenever you heal a patient, you gain:
- Extra sanity.
- A temporary speed boost.
These bonuses become incredibly valuable during chaotic shifts when multiple emergencies happen at once. The movement speed helps you reach patients faster, while the extra sanity keeps you stable during long runs.
Surgeon is arguably the strongest class for experienced players.
Tier: S
Secret Agent
Cost: 320 Robux
Secret Agent starts with a gun that has twenty shots for killing anomalies.
While the extra firepower sounds attractive, guns can already be purchased from the in-game shop after progressing through several shifts. Because of that, spending Robux on this class isn’t necessary.
Tier: D
Best Classes to Use
If you only plan to buy a few classes, these are the most worthwhile choices:
Best Early Game
- Secretary
- Paramedic
Secretary offers cheap and reliable sanity recovery, while Paramedic’s speed boost can save runs.
Best Mid Game
- Doctor
- Paramedic
Doctor provides excellent sanity management, especially if you focus on healing.
Best Late Game
- Surgeon
- Paramedic
Surgeon becomes incredibly powerful during difficult shifts thanks to its combination of sanity restoration and speed boosts.
Most classes in Animal Hospital Anomaly offer small bonuses, but only a few stand out as truly game-changing. Paramedic and Surgeon are easily the strongest overall choices, while Secretary and Doctor provide excellent value for their cost.
On the other hand, classes like Head Nurse, Security, and Secret Agent are harder to recommend since their benefits can already be obtained through normal gameplay. If you’re saving Cat Coins, focusing on S-Tier and A-Tier classes will give you the biggest advantage during longer and more difficult shifts.
