How to Unlock and Handle Mouse Patients

Unlocking specific patient types and handling rare encounters like the mouse requires a clear understanding of the progression system. In Animal Hospital, patient variety and shift difficulty scale as you complete more nights and upgrade your professional class.

1

Earn Permanent Animal Coins

Complete standard night shifts successfully. Each survival run rewards you with cash for immediate shop items and permanent Animal Coins for class progression.

2

Unlock Higher-Tier Classes

Navigate to the class selection menu and spend your Animal Coins to unlock advanced roles such as Doctor, Security, or Surgeon. Higher classes attract a wider variety of patients.

3

Monitor the Reception Desk

As your class level increases, smaller patient types like mice will begin appearing at the check-in counter. Keep your camera angle low to spot them clearly.

4

Execute the Inspection Protocol

Verify the mouse patient's identity card, check the lobby CCTV, and look for physical distortions before admitting them to the treatment rooms.

Class Selection Tip

The Secretary class is highly recommended for beginners focusing on reception duty. It recovers Sanity every time you successfully check in a patient.

Spotting Mouse and Patient Anomalies

Identifying anomalies is the most critical skill in the game. When a small patient like a mouse arrives, its anomalies can be easy to miss due to its small size. You must use every tool at your disposal to verify its status.

Visual Inspection

Check for physical abnormalities such as glowing eyes, human-like teeth, extra limbs, or a distorted wide grin.

CCTV Verification

Switch to the lobby cameras. Some anomalies, like a completely black void body, are only visible through the monitor screen.

Photo Comparison

Compare the live patient with their official file photo. Look out for static effects or bloodshot eyes on the card.

Anomaly CategoryVisual TellSeverityImmediate Action
In-PersonTwitching limbs, realistic teeth, extra eyesCriticalPull the shutter button immediately
CCTV OnlyBlack box over eyes, stretched limbsHighDeny entry using the desk shutters
Photo GlitchGrainy photo, mismatched speciesHighReject the patient and clear the desk
Safe Playstyle

When in doubt, reject the patient. It is much safer to lose a small amount of score for turning away a normal patient than to let a Skinwalker inside.

Treatment Rooms and Item Guide

Once you admit a normal patient, you must guide them to the correct treatment room and apply the appropriate medical tools. Using the wrong item can kill the patient and ruin your shift rating.

Treatment Room Rules:

  • Always check the computer screen before picking up a medical item
  • Never leave a patient in the middle of a Room 8 Surgery sequence
  • Use a Fire Extinguisher immediately if a burning patient emergency occurs
  • Keep a Taser equipped when walking through hallways late at night
Emergency Protocol

If an anomaly slips past your check-in desk, it will transform into a hostile Skinwalker. Use the Security class's X-Taser or the Secret Agent's gun to neutralize the threat before it attacks your patients.

Frequently Asked Questions

You can restore your Sanity by drinking Coffee purchased from the in-game shop, eating food, or using classes like the Surgeon and Doctor which passively recover Sanity upon successful patient treatments.
