Animal Hospital has 11 classes. You pick one in the lobby, and it changes how your shift goes. Some give you more sanity to start with. Others hand you a taser, a fire extinguisher or extra bag space.
This page lists every class, what it costs, and what it does at all three levels. Then it works out which ones are actually worth your coins. A few of the popular picks do not hold up once you look at the numbers. The free class also does better than most people expect.
Quick answer: there are 11 classes. Nine are bought with Animal Coins and two need Robux. The free Intern is the best starting pick. A maxed one begins at 81% sanity, and that beats 8 of the 10 classes you can pay for. The Secretary at 120 coins is the cheapest real upgrade.
How classes work
Classes live in the class shop in the server lobby. Look on the left of your screen, or walk into the big yellow circle next to the ambulance. You buy them with Animal Coins, and two of them need Robux instead.
You only wear one class per shift. It changes how you look, and the name shows up next to your sanity meter once the shift starts.
Every class has three levels
Each class starts at level 1. You raise it with experience that you earn by playing. Level 2 and level 3 make the perk stronger, and sometimes add a whole new one.
This matters more than the class you pick. A level 1 class is often much weaker than the same class at level 3. The Intern is the clearest example, going from 10 bonus sanity up to 20.
All 11 classes and what they cost
Here is the full list. The sanity column is what you start a shift with once the class is at level 3. The normal starting sanity with no class perk is 61 to 65%.

The Firefighter is new. It arrived on 25 July 2026 with the Hazmat Team update. Plenty of class lists still show only 10 classes because they were written before that.
What every class does at each level
This is the part most lists skip. The perk you see in the shop is the level 1 version, and several classes change a lot by level 3.
| Class |
Level 1 |
Level 2 |
Level 3 |
| Intern |
Start with 10 bonus sanity |
Start with 15 bonus sanity |
Start with 20 bonus sanity |
| Nurse |
+1 max inventory capacity (4 slots) |
+2 max inventory capacity (5 slots) |
+3 max inventory capacity (6 slots) |
| Secretary |
Recover 1 sanity when checking in patients |
Recover sanity when checking in patients, +5 bonus sanity |
Recover sanity when checking in patients, +10 bonus sanity |
| Paramedic |
Start with a Large Run Cola (6 uses) |
Start with a Large Run Cola (9 uses) |
Start with a Large Run Cola (9 uses), regains 1 use each round |
| Psychologist |
All sanity effects are doubled, good and bad |
All effects doubled, 7.5% chance to ignore a sanity loss |
All effects doubled, 15% chance to ignore a sanity loss |
| Doctor |
Recover 1 sanity when healing patients |
Recover sanity when healing patients, +15 bonus sanity |
Recover sanity when healing patients, +20 bonus sanity |
| Firefighter |
Start with a Fire Extinguisher, +1 max inventory capacity |
Recover 1 sanity when putting out fires |

| Security |
Start with an X-Taser (5 uses) |
Start with an X-Taser and a Deployable Camera |
X-Taser and Deployable Camera, taser regains 1 use each round |
| Surgeon |
Sanity and a short speed boost after healing a patient |
Sanity and a longer 8 second speed boost after healing |
Double sanity and a longer speed boost, +10 bonus sanity |
| Head Nurse |
+3 max inventory capacity (6 slots) |
+3 max inventory capacity, +10 bonus sanity |
+3 capacity, start each round with every treatment already packed |
| Secret Agent |
Start with a gun (20 uses) and a scanner, +2 carry capacity |
Gun has 24 uses and regains 1 use each round |
Killing anomalies with the gun gives +4 sanity and +5 cash |
Look at Security. At level 1 you get a taser with 5 uses. At level 3 you also get a Deployable Camera, and the taser refills 1 use every round. That is a free tool every shift, so you stop buying tasers with your shift money.
The Psychologist is not the tank it looks like
The Psychologist starts at 100% sanity. Every other class starts at 61 to 65%. That looks like the best survival class in the game by a mile, and it is the reason people save up 500 coins for it.
But it doubles all sanity effects, and that includes the bad ones. Levels 2 and 3 only add a small chance to ignore a loss. So here is what you really take:
| Level |
Damage you take |
What 100% really absorbs |
| Level 1 |
2 times normal |
50 points |
| Level 2 |
1.85 times normal |
54.1 points |
| Level 3 |
1.7 times normal |
58.8 points |
A free class lasts longer. A normal class starts at 61 to 65 and takes normal damage. The Psychologist starts at 100 but burns through it faster. Even at level 3 it soaks up about 58.8 points, which is below the 61 a free class gets.
So what are the 500 coins buying? Healing speed. A coffee gives you 30 sanity instead of 15. A chocolate bar gives 120 instead of 60. Job stress is left out of the doubling, so the slow drain does not get worse.
That makes it a strong class for players who already know the checks and can keep the coffee coming. It is a poor class while you are still learning, because one wrong tase costs you 30 sanity instead of 15.
The free class beats most paid ones
The Intern is the class you already own. It gives bonus starting sanity, and at level 3 that bonus is 20 points. You start at 81%.
Now compare that with everything you can buy. Only two paid classes match or beat it. The Doctor reaches 81 to 86%, and the Psychologist shows 100% but really absorbs less, as above.
The other 8 paid classes all start lower than a maxed Intern. That includes the 2,500 coin Surgeon and both Robux classes. If you only care about lasting longer in a shift, you already have the second best option.
This does not mean the paid classes are bad. They give tools, bag space and money that the Intern never will. It means you should buy them for what they carry, not to survive longer.
What a point of sanity actually costs
If you are buying a class just to start higher, this is the rate you are paying at level 3.
| Class |
Cost |
Bonus sanity |
Coins per point |
| Secretary |
120 coins |
10 points |
12 coins |
| Doctor |
900 coins |
20 points |
45 coins |
| Firefighter |
1,100 coins |
10 points |
110 coins |
| Surgeon |
2,500 coins |
10 points |
250 coins |
The Secretary is far and away the cheapest at 12 coins a point. The Surgeon charges about 20 times more for the same stat. The Surgeon does other things too, but nobody should buy it for the sanity.
What levelling a class costs
Experience is shared out as you play. You spend it on whichever class you want to raise.
| Step |
Experience |
Or pay Robux |
| Level 1 to 2 |
200 EXP |
199 Robux |
| Level 2 to 3 |
850 EXP |
299 Robux |
| Full class |
1,050 EXP |
498 Robux |
The second step is the expensive one. Level 3 costs 4.25 times as much experience as level 2 did. Plenty of players get every class to level 2 and stop there, which is a reasonable plan.
Maxing all 11 classes takes 11,550 experience. Skipping all of it with Robux would cost 5,478. Levelling the one class you actually play is much better value than spreading it thin.
How to get Animal Coins
Animal Coins only come from a few places, and one of them is worth far more than the rest.
| What you do |
Coins |
Notes |
| Treat a patient |
2 coins |
The fastest way by far |
| Stop an anomaly |
0.5 coins |
Adds up over a long shift |
| Let a visitor in |
0.5 coins |
Easy coins at the window |
| Buy from the shop nurse |
1 to 3 coins |
Costs 100 dollars in game |
Treat patients. At 2 coins each it pays four times what an anomaly or a visitor does. If you are saving for a class, take the jobs that put animals in front of you.
To put a number on it, every class you can buy with coins adds up to 6,640 Animal Coins. That is about 3,320 patients treated. It is a long project, so pick one class and finish it.
Coin packs, and which one is worth it
You can also buy coins with Robux. The four packs are not priced evenly, and the small one is poor value.
| Pack |
Price |
Per coin |
Verdict |
| 100 coins |
99 Robux |
0.99 Robux |
Worst value |
| 500 coins |
380 Robux |
0.76 Robux |
|
| 1,500 coins |
890 Robux |
0.59 Robux |
|
| 3,250 coins |
1590 Robux |
0.49 Robux |
Best value |
The biggest pack works out at about 0.49 Robux a coin. The smallest is 0.99. You pay twice as much per coin for buying small, which is the usual pattern but worth seeing written down.
Buying every coin class outright would take about 3,378 Robux, using two big packs and two small ones. That is a lot of money for something you can earn by playing, so treat these packs as a shortcut, not a plan.
The two Robux classes
The Head Nurse and the Secret Agent cannot be bought with coins at all. They are the only two that need real Robux.
| Class |
Price range |
What you get |
| Head Nurse |
80 to 240 Robux |
6 bag slots, $30 to start, and every treatment pre-packed at level 3 |
| Secret Agent |
360 to 1,070 Robux |
A gun and a scanner, $50 to start, and sanity for each anomaly you shoot |
Why the price is a range. Roblox charges different amounts in different countries for these two, so there is no single correct number. Guides that print one exact price are showing you what they saw in their own country. Check the shop in your own game.
One warning on the Secret Agent gun. It has friendly fire, so you can shoot a teammate by mistake. That costs you sanity as well as them.
Which class should you pick
The honest answer changes with how long you have played. Here is the order the numbers point to.
- Brand new. Stay on the Intern and put your first experience into it. Free, and it out-starts nearly everything.
- First 120 coins. The Secretary. It is the cheapest bonus sanity in the game and it pays you for work you already do at the window.
- Playing on your own. Security. The free taser every round means you can deal with an anomaly without spending shift money, and the camera at level 3 covers the checks you cannot reach.
- Confident with the checks. The Psychologist, but only now. Double healing is strong once you stop making wrong calls.
- Playing with friends who heal. The Doctor. It has the highest starting sanity you can buy with coins, and it pays you for treating.
Whatever you pick, level it up before you buy the next one. A level 3 cheap class beats a level 1 expensive one nearly every time.
Animal Hospital classes FAQ
What is the best class in Animal Hospital?
It depends on what you need. For staying alive, a maxed Intern starts at 81% sanity and costs nothing. For coins, the Secretary is the cheapest way to raise your starting sanity. For dealing with anomalies, Security hands you a free taser every round once it is maxed.
What is the best class for a beginner?
Stay on the Intern and level it up. It is free, and it starts you higher than 8 of the 10 paid classes. The extra sanity gives you room to make mistakes while you learn.
Is the Psychologist worth 500 coins?
Only if you already play well. It starts at 100% sanity, but it doubles every loss too. That means it soaks up less punishment than a free class does. What you really get is double healing from coffee and chocolate.
How many classes are there?
There are 11 right now. The Firefighter is the newest and arrived on 25 July 2026 with the Hazmat Team update. Lists that show only 10 were written before that.
How do you level up a class?
You earn experience by playing. Getting a class to level 2 takes 200 experience, and level 3 takes another 850. That is 1,050 in total for one class.
Can you skip the wait with Robux?
Yes. Level 2 costs 199 Robux and level 3 costs 299, so 498 Robux maxes one class. Doing that for all 11 would cost 5,478 Robux.
How do you get Animal Coins fast?
Treat patients. Each one gives 2 coins, which is four times what you get for stopping an anomaly or letting a visitor in. Long shifts with lots of treatments pay best.
Which classes need Robux?
Only two. The Head Nurse and the Secret Agent cannot be bought with Animal Coins. Their price changes depending on where you live, so the number you see may not match a guide.
