In Animal Hospital (a horror game on Roblox), Classes are more than just skins—they determine how you survive each Shift: your starting Sanity, inventory slots, Sanity recovery during check-ins and treatments, and even your starting equipment. This Animal Hospital Class guide covers all 10 classes, their unlock prices in Animal Coins / Robux, Sanity and inventory bonuses, and starting items.
Beyond the breakdown, we’ve included a practical Animal Hospital tier list, explaining why the Surgeon is widely considered the best class for F2P players, along with the most efficient Animal Hospital class recommendations for progression from beginner to endgame. You'll know exactly where to spend every Animal Coin.
Career System Overview: What do Classes actually change?
Many newcomers enter Animal Hospital thinking classes are just cosmetic, only to have their Sanity bottom out and get dragged away by an anomaly. In reality, your class is the most important part of your starting loadout.
There are 10 classes in Animal Hospital. Each changes your character model and provides a core bonus. These bonuses revolve around the game's three survival pillars: Sanity (game over if it hits 0), Inventory Capacity (how many items you can carry), and Starting Items / Weapons. In other words, choosing a class defines your survival foundation for the match.
Each class has 3 upgrade levels, with bonuses increasing at higher levels (e.g., the Intern's starting Sanity increases from +10 to +20). To be honest: the exact costs for each upgrade level are not fully documented by the community yet. This page only lists confirmed unlock prices; upgrade costs are marked as "TBA" until official or wiki sources are updated.
Classes are unlocked using Animal Coins or Robux. The first 8 classes use Animal Coins (ranging from free to 2,500 coins), while the last 2 (Head Nurse, Agent) are Robux exclusive. Animal Coins must be earned through gameplay, while Robux allows you to skip the grind.
All 10 Classes: Unlock Prices and Bonuses Overview
Here is the summary table. We have listed the unlock price and core bonus for every class to help you compare their value.
| Class | Unlock Price | Core Bonus |
|---|---|---|
| Intern | Free | Starting Sanity +10 → +20 (scales with level) |
| Nurse | 20 Animal Coins | Inventory Capacity +1 → +3 |
| Secretary | 120 Animal Coins | +1 Sanity per check-in |
| Paramedic | 250 Animal Coins | Starts with Speed Cola |
| Psychologist | 500 Animal Coins | All Sanity effects doubled (high risk); start with 100% Sanity |
| Doctor | 900 Animal Coins | +1 Sanity per heal |
| Security | 1,250 Animal Coins | Start with X-Taser |
| Surgeon | 2,500 Animal Coins | Gain Sanity + movement speed boost after healing |
| Head Nurse | 190 Robux | Inventory capacity +3 |
| Secret Agent | 790 Robux | Start with a gun |
Animal Hospital tier list: Rankings and best class
The following Animal Hospital tier list synthesizes confirmed class bonuses and community consensus. Note: Except for "Surgeon = S-tier best F2P," which is a highly consistent community conclusion, other tiers are assessments based on the editor's analysis of mechanics. Community data varies, so use this as a reference only.
| Tier | Class | Reasoning |
|---|---|---|
| S-tier | Surgeon | Heals grant both Sanity and speed boosts; best sustainability. Community-agreed ultimate F2P goal and best class |
| A-tier (Editor assessment) | Doctor, Security | Stable Sanity recovery / Start with X-Taser; reliable mid-to-late game strength |
| B-tier (Editor assessment) | Secretary, Paramedic | Restore Sanity upon reception / Start with Speed Cola, a practical transition while saving up for the Surgeon |
| High risk, high reward | Psychologist | Sanity gains are doubled, but Sanity losses are also doubled—extremely strong if you play steadily, but collapses the fastest |
| Beginner's guide | Intern, Nurse | Free / Only 20 Animal Coins, the top choice for increasing survival rates in the early stages |
| Robux convenience | Head Nurse, Secret Agent | Skip coin grinding with direct payment: +3 inventory slots / Start with a gun; saves time but isn't overwhelmingly powerful |
Beginners should start with the free Intern, then save up 20 coins to switch to the Nurse to expand inventory; there is only one long-term goal—dump all your Animal Coins into the 2,500-coin Surgeon. This is the most stable Animal Hospital career recommendation route.
Breakdown: 10 career details
After looking at the table, let's go over the playstyle, target audience, and usage of each career one by one.
Intern
Countermeasures：The starting career for everyone. Higher starting Sanity means you can take a few more hits from the same scares, which is usually enough for a beginner's first few Shifts.
Nurse
Countermeasures：The cheapest paid career. Adds 1 to 3 inventory slots, allowing you to carry more first aid / speed items, making Shifts much easier. The first stop before saving for the Surgeon.
Secretary
Countermeasures：Gain +1 Sanity every time you complete a check-in at the reception window. Since you'll be checking in patients frequently, your Sanity will recover steadily—perfect for players who like to camp at the window and screen patients.
Paramedic
Countermeasures：Start the shift with a bottle of Speed Cola to increase mobility when fleeing or running to the medical room. Saves you the trouble of gathering items at the start.
Psychologist
Countermeasures：All Sanity effects are doubled—both recovery and loss—and you start with 100% Sanity. Extremely powerful if played well, but you'll collapse quickly if hit by an anomaly combo. High risk, high reward.
Doctor
Countermeasures：Restores +1 Sanity for every completed heal. As long as you diligently play the healing minigames in the medical room, you will rarely run out of Sanity; it's a very stable choice for the mid-to-late game.
Security
Countermeasures：Starts with an X-Taser, providing self-defense against wandering enemies; combat-ready from the start. Focuses on defense and countering threats like the Skinwalker.
Surgeon
Countermeasures：Gain both Sanity restoration and a movement speed boost after healing, combining offense, defense, and sustainability. Widely recognized by the community as the best F2P class and the ultimate goal for most players saving up Animal Coins; it is the undisputed best class.
Head Nurse
Countermeasures：Robux exclusive. Instantly adds +3 backpack slots, equivalent to a max-level nurse backpack. Perfect for players who want to save time gathering Animal Coins and prefer carrying more items.
Secret Agent
Countermeasures：Robux exclusive. Starts with a gun, providing the best long-range self-defense. Note that the price has been increased from the old 320 to 790 Robux (see the Patch Drift section for details).
Sanity Bonus Breakdown: Intern / Secretary / Doctor / Psychologist / Surgeon
Sanity is the lifeblood of Animal Hospital—if it hits zero, you're out. Several roles revolve around Sanity, but they trigger in different ways, so understanding them is key to making the right choice.
Starting Sanity Type—Intern. Instead of regenerating, it raises your base Sanity cap, increasing your starting Sanity from +10 to +20 (scaling with level). This is the most beginner-friendly option: while you're still learning to identify an Animal Anomaly and getting startled, this extra buffer is often the difference between life and death.
Continuous Recovery Type—Secretary, Doctor, Surgeon. The Secretary recovers Sanity by checking in patients (+1 per check-in), the Doctor recovers it by treating patients (+1 per heal), and the Surgeon provides a bonus to both Sanity and movement speed after treatment. All three reward active gameplay; the more you do, the higher the return. The Surgeon is considered S-tier because the added speed makes escaping and navigating the clinic much easier.
The Psychologist doubles all Sanity effects—this means while healing is doubled, Sanity loss when startled by an Animal Anomaly is also doubled. Although you start with 100% Sanity, if you make a few mistakes in a row, you will collapse twice as fast as others. It is a classic high-risk, high-reward role suited for veterans who have mastered the patterns of every Animal Anomaly.
Backpack and Starting Items: Nurse / Head Nurse / Medic / Security / Secret Agent
The other bonus path doesn't touch Sanity, but ensures you are better equipped from the start: either with a larger backpack or by holding items or weapons right away.
Backpack Expansion—Nurse, Head Nurse. The Nurse provides +1 to +3 backpack capacity based on level, while the Head Nurse (Robux) provides +3 instantly. A larger backpack means you can stock more first-aid, speed, and self-defense items, giving you more options during emergencies. Both are similar at max level; the difference is whether you grind with Animal Coins or use Robux to get it instantly.
| Role | Starting Equipment | Unlock Price | Usage |
|---|---|---|---|
| Paramedic | Speed Cola | 250 Animal Coins | Boosts mobility, making it faster to escape or rush to the medical room. |
| Security | X-Taser | 1,250 Animal Coins | Close-quarters self-defense for dealing with wandering enemies / Skinwalker. |
| Secret Agent | A gun | 790 Robux | Long-range self-defense, the strongest starting firepower. |
In terms of combat self-defense strength, Secret Agent (starting gun) > Security (X-Taser) > Paramedic (Speed Cola, focused on mobility rather than attack). But remember, the tone of Animal Hospital is 'slow-creeping dread rather than constant jumpscares'; most of the time you rely on identifying the anomaly and using the shutter to reject patients, rather than head-on combat, so weapons are more of a safety net than a core mechanic.
How to earn Animal Coins: The only job currency
The first 8 classes all require Animal Coins, and these coins have only one purpose—buying classes. Therefore, your coin-earning efficiency directly determines how quickly you can unlock the Surgeon.
- Complete a Shift (Main source)
Completing a Shift (level rotation) rewards Animal Coins, with about 5 coins for the 1st Shift. The longer you survive and the more shifts you clear, the more you accumulate. This is the primary source for free-to-play players.
- Exchange Cash at the Supplies Shop with the Shop Nurse
Find the Shop Nurse in the Supplies Shop to exchange in-game Cash: $100 Cash → 1-3 Animal Coins. The exchange amount has a random range, so be prepared for some inconsistency when saving up for large amounts.
- Purchase or gift directly with Robux
You can buy Animal Coins directly with Robux, or gift them to friends. Players who want to skip the grind and quickly unlock the Surgeon can take this route.
Animal Coins cannot be used to buy items or anything else; their only use is unlocking/upgrading classes. So don't worry about 'saving them for something else'—if you have enough for your target class, buy it without hesitation.
Let's do the math: The Surgeon costs 2,500 coins. If you rely mainly on shifts (starting at about 5 coins, with more accumulated based on survival time), this is a significant grind. You could unlock cheaper classes like the Nurse (20 coins) or Secretary (120 coins) along the way to improve your experience, but exercise restraint—every transition class you buy puts you further away from the Surgeon.
Are Robux classes worth it: Head Nurse and Secret Agent
The Head Nurse (190 Robux) and Secret Agent (790 Robux) are the only two Robux-exclusive classes. Whether spending money is worth it depends on what you're looking for.
Bottom line: Robux classes primarily offer 'convenience' and 'time-saving' rather than overwhelming power. The Head Nurse's +3 inventory slots can be achieved by a max-level Nurse; the Secret Agent's starting gun is strong, but the core of the game remains identifying the anomaly and using the shutter, with weapons serving as a backup. If you have limited time and don't want to grind for Animal Coins, spending money can save you from playing many extra shifts.
Some older guides state the Secret Agent is 320 Robux, but since the Class Update Pt.1, the developers have increased it to 790 Robux. This page uses the new price of 790. Don't be misled by old numbers.
Advice for F2P players: Aim for the Surgeon, and only buy Robux classes if you really need them. If you are willing to spend, the Head Nurse (190 Robux) is usually better value than the Agent (790 Robux) because the inventory expansion provides a constant benefit every round, whereas the starting gun isn't used that often in this slow-paced, psychological horror game.
Beginner to late game: Animal Hospital class upgrade guide
Putting the above information together gives you a clear growth path. The following Animal Hospital class recommendation route is suitable for the vast majority of F2P players.
- Stage 1: Starting as a free Intern
New players should stick with the free Intern. The higher starting Sanity (+10→+20) allows you to survive a few more scares while you're still unfamiliar with the Animal Anomaly, helping you build a solid foundation for survival and get used to the reception and shutter mechanics.
- Stage 2: Spend 20 coins to upgrade to Nurse for inventory space
Save up 20 Animal Coins and switch to the Nurse immediately. The extra 1-3 inventory slots let you stock up on first aid/speed items to handle emergencies more calmly; this is the most cost-effective first investment.
- Stage 3: Choose a transitional class as needed (optional)
If you want to improve your experience, you can consider the Secretary (120 coins, restores Sanity upon reception) or the Medic (250 coins, starts with Speed Cola). But remember, every purchase puts you further from your ultimate goal, so if your budget is tight, just skip this and save your money.
- Stage 4: Go all out for the 2,500 coin Surgeon
The ultimate goal is the Surgeon. The dual bonus of Sanity and speed after treatment makes it unmatched in long rounds, and it is widely recognized as the best class for F2P. Once you save up 2,500 coins, grab it without hesitation; you can basically use it for all long-term play thereafter.
Players who don't want to grind can use Robux to buy Animal Coins to unlock the Surgeon faster, or start with the Head Nurse (190 Robux) for the +3 inventory space as a transition. Regardless of whether you spend money or not, the Surgeon is the final destination.
Psychologist: High-risk, high-reward advanced gameplay
The Psychologist (500 Animal Coins) deserves a special mention because it has the most unique mechanics in the game and is the most demanding in terms of skill.
Its mechanic is that all Sanity effects are doubled, and you start with 100% full Sanity. The theoretical ceiling is extremely high: combined with the "continuous Sanity recovery" playstyle of the Doctor / Secretary / Surgeon, the recovery efficiency after doubling is amazing. But conversely, the Sanity loss when scared by an Animal Anomaly or hitting a jumpscare is also doubled, leaving almost no room for error.
It is not for beginners. Only when you can reliably identify an Animal Anomaly and rarely get scared will the doubling mechanic lean in your favor. New players using it often see their Sanity collapse twice as fast and get eliminated early. Treat it as an advanced choice for when you are skilled, not an early-game investment.
Prices change: Patch drift and data reliability note
Animal Hospital is a hit new game released in May 2026 (approx. 45.2 million visits, peak concurrent players of approx. 135,000, 95.8% positive rating), and it is patched almost daily, with stats and prices changing frequently.
All class prices and bonuses on this page are current as of the mid-June patch, primarily referenced from the official wiki (Fandom). However, please treat this as a "snapshot" rather than an eternal truth: the Agent increasing from 320 to 790 Robux is a prime example. After the next major update (such as subsequent versions of the Class Update), prices or bonuses may change again.
For anything not fully documented by the community (such as the specific costs for each level of class upgrades), this page will be marked as "undisclosed" and we will never fabricate numbers. In the tier list, except for the Surgeon = S-tier which is a community consensus, other rankings are editorial assessments, and community opinions vary. If you see values that do not match the game, please refer to the current in-game patch.
FAQ

Which is the best class in Animal Hospital?
The community consensus is the Surgeon (2,500 Animal Coins). It provides both Sanity recovery and movement speed bonuses after treatment, combining offense and defense, making it the ultimate goal most worth saving for by F2P players, and it is a stable S-tier class in every Animal Hospital tier list.
How to earn Animal Coins quickly?
There are three main ways: ① Complete Shift rewards, Shift 1 gives about 5 coins, and the longer you survive, the more you get; ② Exchange Cash at the Supplies Shop with the Shop Nurse, $100 Cash for 1-3 coins; ③ Buy directly with Robux, or have a friend gift them to you using Robux. Note that Animal Coins can only be used to buy classes and have no other use.
Is it worth spending Robux on classes (Head Nurse / Agent)?
You are mainly paying to "save time" rather than for overwhelming power. The Head Nurse (190 Robux) provides +3 inventory space, and the Agent (790 Robux) starts with a gun. Neither is a must-buy—the Nurse can also get a large inventory at max level, and the core of the game is identifying an Animal Anomaly and using the shutter; weapons are just a safety net. If your budget is limited, focus on saving for the Surgeon.
Is the free Intern good enough?
Perfectly adequate for the early game and the best starting point for beginners. The Intern provides starting Sanity +10 → +20 (scaling with level), allowing you to take more hits while you are still learning the Animal Anomaly and prone to getting jumpscared. It is fine to wait until you save up 20 Animal Coins to switch to the Nurse.
How many Animal Coins does the Surgeon cost? How long does it take to grind?
It costs 2,500 Animal Coins. If you rely primarily on Shifts (starting at about 5 coins, increasing with survival time), this is quite a long grind. Along the way, you can improve your experience by using the free Intern and the 20-coin Nurse; if you don't want to grind, you can also use Robux to buy Animal Coins to speed things up.
Why is the Psychologist considered high risk?
Because it doubles all Sanity effects: while doubled Sanity recovery is great, the Sanity loss when scared by an Animal Anomaly is also doubled, leaving very little room for error. Although you start at 100% Sanity, it will plummet rapidly if you make consecutive mistakes. It is better suited for veterans who have mastered the patterns of the Animal Anomaly and is not recommended for beginners.
How much does it cost to upgrade a class to Level 2 or 3?
Each class has 3 upgrade levels, and the higher the level, the stronger the bonus (e.g., the Intern goes from +10 to +20). However, the specific costs for each upgrade level are not fully documented in community resources yet. This page marks them as "undisclosed" to avoid making up numbers, and we will update them once authoritative sources provide the data.
Is the Agent 320 or 790 Robux?
Use 790 Robux as the current price. The 320 Robux figure seen in early guides is the old price; the developers increased it to 790 after the Class Update Pt.1. Any mention of 320 is outdated information.
What is the difference between the starting items for Security and Medical?
Security (1,250 Animal Coins) starts with an X-Taser, which is better for close-range self-defense; Medical (250 Animal Coins) starts with Speed Cola, which is better for mobility and escaping. One provides a combat safety net, the other provides a movement advantage.
Does choosing a class change the character's appearance?
Yes. Every class changes your character model (appearance), so changing your class changes both your gameplay foundation and your look.
Which class should a beginner unlock first?
We recommend starting with the free Intern to build a foundation, then unlocking the Nurse as your first purchase once you have 20 Animal Coins to expand your inventory (+1 → +3 slots). This is the most cost-effective first investment. Afterward, save your money for the 2,500-coin Surgeon.
Can Animal Coins be used for anything other than buying classes?
No. The only use for Animal Coins is to unlock/upgrade classes; they cannot be used to buy items or anything else. Therefore, once you have saved enough for your target class, spend them without hesitation, as there is no need to save them for other purposes.
