Every Animal Hospital Class & Which to Buy

Classes change how you play Animal Hospital — each one has a different perk and a three-level upgrade path, bought with Animal Coins. Here's the full roster and where to spend first.

The 10 classes

• Doctor — recovers Sanity when healing patients (great for long runs).
• Surgeon — built for the Room 8 surgery minigame.
• Nurse — cheap starter; +inventory capacity.
• Head Nurse — an upgraded support role.
• Intern — boosts your starting Sanity.
• Paramedic — mobility/response focused.
• Psychologist — gets more Sanity from coffee (+30 instead of +15).
• Secretary — admin/economy utility.
• Security — anomaly and enemy defense.
• Secret Agent — starts with a Gun, the best anomaly counter.

How to unlock them

Every class is bought with Animal Coins, the persistent currency you earn across runs. Each class then has three upgrade levels that strengthen its perk.

Which class to buy first

• New players: the Nurse is cheap and the extra inventory helps you carry more items.
• For survival: the Doctor and Intern keep your Sanity topped up, which is the thing most likely to end your run.
• For anomalies: the Secret Agent starts armed, so you can neutralise threats immediately.

Save your Animal Coins for one class you'll actually main, then upgrade it to level 3 before branching out.
