Animal Hospital Patient Treatment Guide

How to treat patients in Animal Hospital: a complete guide to Basic Medical, X-Ray, Heart Monitor and Surgery rooms, plus the wrong-item Anomaly trick.

Last updated: June 19, 2026

Once you have admitted a genuine patient through the check-in routine, it is time to cure them. Treatment is where you actually earn your score — and where a careless mistake can undo a clean shift. This hub covers all four treatment types and the rooms they happen in.

The four treatment types

There are eight numbered rooms, grouped into four kinds of treatment:

  • Basic Medical Treatment (rooms 1–5, on the right) — the most common case. Analyze the patient’s DNA, then administer the correct items.
  • X-Ray (room 6, on the left) — a copy-the-sequence mini-game followed by administering items.
  • Heart Monitor (room 7, on the left) — click white icons while avoiding skulls to reach 100%, then administer items.
  • Surgery (room 8, on the left) — a timed, on-the-spot mini-game you cannot leave once it begins.

The golden rule: match items carefully

Across every treatment type, the most important rule is the same: administering the wrong item kills the patient and costs you points. Most treatments end by giving the patient one or more items, and a wrong choice there erases all the work you just did. Slow down for the item step. When you must give multiple items at once, the order usually does not matter — but giving even one wrong item is fatal.

You can multitask (except Surgery)

For Basic Medical, X-Ray and Heart Monitor, you do not have to babysit the patient the whole time. The DNA analysis step takes about 10 seconds, and the post-treatment recovery period runs on its own — non-Anomaly patients recover and leave by themselves. So a smart routine is to start a treatment, step away to check in more patients or handle an event, and return when needed.

Surgery is the exception. It is timed and must be completed on the spot; once you interact with the patient to begin, you cannot leave the room until it is done or the patient dies.

The wrong-item Anomaly trick

Here is one of the most useful tricks in the game: if an Anomaly slipped through your check-in and you admitted it, you can deal with it during treatment by deliberately giving it the wrong item. Because Anomalies dying does not cost you points, this kills the disguised monster cleanly with no scoring penalty — a neat way to fix a missed rejection without firing a weapon. It is often safer than letting it awaken into a roaming Skinwalker.

Treatment efficiency

Because treatment outside emergencies is untimed and order-independent, plan your route for efficiency. Many players check in all waiting patients first, then sweep through the rooms — handling the right-side Basic Medical rooms together, then the left-side specialized rooms. Use the Hospital Map to minimize back-and-forth, and keep an eye out for events that interrupt the flow, like a Death Ritual starting in a room you were about to enter.

Watch for in-room threats

Treatment rooms are not always safe. The Bed Monster spawns under beds, the Don’t Look Up threat appears on ceilings, and Surgery tentacles interfere during operations. Each has a specific, non-combat response covered in the Enemies section. Learn those alongside the room guides below so a treatment never turns into a Sanity disaster. Start with the most common type: Basic Medical Treatment.

Frequently asked questions

What happens if I give the wrong treatment item?

The patient dies and you lose points. Match items carefully. The one exception: if the 'patient' is actually a missed Anomaly, killing it with the wrong item costs no points and is a handy cleanup trick.

Do I have to stay in the room during treatment?

For most treatments, no — you can leave during DNA analysis or recovery and do something else, then return. Surgery is the exception: once it starts you must finish it on the spot within the time limit.

Does treatment order matter?

Outside of timed emergencies, no. You can treat admitted patients in any order and take as long as you need, so pick the most efficient route through the rooms.
