All Classes Animal Hospital Anomaly Tier List & Best One to Use

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. Before choosing a class, it’s important to understand the three new rating bars introduced in the update.

What’s New Things Coming with Animal Hospital New Update?

Sanity

The Sanity bar measures how well a class helps maintain your mental state throughout a match. Classes with higher Sanity ratings make it easier to avoid sanity loss, reducing the need to constantly rely on coffee and other recovery items.

Utility

Utility shows how helpful a class is during normal gameplay. High Utility classes often support teammates, improve efficiency, or make it easier to survive dangerous events and anomalies.

Starter Money

Starter Money reflects how much economic value a class provides at the beginning of a match. A higher rating usually means you’ll gain access to useful items and upgrades earlier than other players.

Intern

Intern is the default class that every player starts with.

Level Bonuses

Level 1

• Start with +10 Sanity

Level 2

• Start with +15 Sanity

Level 3

• Start with +20 Sanity

Ratings

• Sanity: 25%
• Utility: 0%
• Starter Money: 0%

Is Intern Worth Using?

Intern is designed for beginners. The extra starting sanity helps new players survive their first few rounds, especially while learning game mechanics. However, once that bonus is gone, the class offers no additional benefits. It’s a good starting point, but you’ll eventually want to unlock something stronger.

Nurse

Nurse specializes in increasing inventory space.

Level Bonuses

Level 1

• +1 Inventory Slot

Level 2

• +2 Inventory Slots

Level 3

• +3 Inventory Slots

Ratings

• Utility: 50%

Is Nurse Worth Using?

Extra inventory makes carrying treatment supplies, coffee, emergency tools, and teddy bears much easier. While this can be useful, Nurse is generally considered more of a stepping stone toward Head Nurse rather than a long-term class.

Secretary

Secretary is one of the best choices for players who frequently check in patients.

Level Bonuses

Level 1

• Restore 1 Sanity after checking in a patient

Level 2

• Restore 1 Sanity per patient
• +5 Starting Sanity

Level 3

• Restore 1 Sanity per patient
• +10 Starting Sanity

Ratings

• Sanity: 50%
• Utility: 10%
• Starter Money: 20%

Is Secretary Worth Using?

Since patient check-ins happen constantly during every match, Secretary provides reliable sanity recovery throughout the game. The steady regeneration makes it a strong and beginner-friendly option for players who enjoy handling the front desk.

Paramedic

Paramedic focuses on movement speed.

Level Bonuses

Level 1

• Start with a Speed Cola (6 uses)

Level 2

• Speed Cola upgraded to 9 uses

Level 3

• Speed Cola has 9 uses
• Gain one additional Speed Cola use every round

Ratings

• Utility: 80%

Is Paramedic Worth Using?

Being able to move faster helps with nearly every task, including gathering supplies, reaching patients, escaping enemies, and responding to emergencies. Even without sanity bonuses, the mobility alone makes Paramedic one of the strongest support classes.

Psychologist

Psychologist offers one of the highest skill ceilings in the game.

Level Bonuses

Level 1

• All sanity gains and losses are doubled

Level 2

• Sanity effects remain doubled
• 7.5% chance to ignore sanity loss

Level 3

• 15% chance to ignore sanity loss

Ratings

• Sanity: 100%
• Utility: 15%

Is Psychologist Worth Using?

This class can be extremely powerful in experienced hands. Doubling positive sanity effects allows players to recover quickly, but the increased sanity loss creates additional risk. Newer players may struggle with the mechanic, while veterans can take full advantage of it.

Doctor

Doctor rewards players for treating patients.

Level Bonuses

Level 1

• Healing patients restores 1 Sanity
• +10 Starting Sanity

Level 2

• Healing restores Sanity
• +15 Starting Sanity

Level 3

• Healing restores Sanity
• +20 Starting Sanity

Ratings

• Sanity: 80%
• Utility: 50%

Is Doctor Worth Using?

Doctor naturally restores sanity while performing normal duties. Because you’re rewarded simply for healing patients, the class remains effective throughout an entire match and greatly reduces the need for sanity recovery items.

Security

Security specializes in protecting the team from dangerous threats.

Level Bonuses

Level 1

• X Taser with 5 charges

Level 2

• X Taser upgraded to 6 charges

Level 3

• X Taser has 6 charges
• Recover one Taser charge every round

Ratings

• Utility: 90%
• Starter Money: 25%

Is Security Worth Using?

The X Taser can quickly disable dangerous enemies and save teammates during emergencies. Thanks to its crowd-control abilities, Security is one of the most valuable support classes available.

Head Nurse is the upgraded version of Nurse with several additional bonuses.

Level Bonuses

Level 1

• +3 Inventory Slots

Level 2

• +3 Inventory Slots
• +10 Starting Sanity

Level 3

• +3 Inventory Slots
• Begin every round with all required medical supplies

Ratings

• Sanity: 50%

Final Thoughts

The updated class system gives every role a much clearer identity, making it easier to choose a class that matches your preferred playstyle. Whether you want better mobility, stronger sanity management, extra inventory space, or powerful support abilities, there’s now a class built for every type of player.

For overall value, Surgeon, Secret Agent, Head Nurse, and Security stand out as some of the strongest choices, while Secretary and Doctor remain excellent options for players who are still learning the game.

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.
