Animal Hospital is a Roblox survival game where you take on the role of a doctor or nurse working the night shift at a veterinary hospital.
Your main responsibilities include admitting animal patients, diagnosing illnesses, assigning rooms, and providing the correct treatment to keep the hospital running smoothly.
The hospital is secretly under attack by mysterious Anomalies that disguise themselves as ordinary animals to sneak inside.
As each night passes, these Anomalies become more dangerous and harder to detect, forcing you to stay alert and carefully inspect every patient before admitting them to the hospital.
In this guide, you’ll learn how to get and use the Key in Animal Hospital (Ratthew Lore), including all the requirements and a complete step-by-step walkthrough to unlock this hidden secret.
How to GET the key (Ratthew)
- Play night shifts until Ratthew (black rat) appears (usually Shift 8–10).
- Serve him and listen to his dialogue.
- After he leaves, pick up the key he drops on the chair/ground.
If you haven’t encountered Ratthew yet, don’t worry.
His appearance is tied to a random event, so he won’t show up at a fixed time for every player.
According to most player guides, Ratthew typically appears by around Shift 10, although he may show up slightly earlier or later depending on your luck.
How to USE the key (secret safe)
- Go to Room 5 (middle of first hallway, near cat poster).
- Pull down the poster on the wall.
- Use the key on the hidden safe.
- Open it to find Ratthew’s lore items.
It’s a lore easter egg that reveals more about Ratthew, his sister, and the Animal Corporation.
