Animal Hospital hides one of its bigger lore reveals behind a key that's easy to miss if you don't know what to look for. The key comes from a recurring character named Ratthew, and using it unlocks a safe that ties directly into the game's ongoing storyline about a missing scientist and a government conspiracy. Here's exactly how to get the key, where to use it, and what the lore behind it actually means.

The key drops from Ratthew, a black animal character who visits the hospital periodically. You need to serve him during his visits, and the key appears after enough interactions. Mostly you will see him appear around Shift 8 to 10.
When Ratthew visits, he sits in your office and talks about the Animal Corporation hunting him down, along with mentioning his missing sister. Once the conversation ends and he leaves, he drops the key on the spot where he was sitting. Pick it up before moving on.
NOTE: Ratthew's visits and dialogue are tied to the game's hidden lore. He explains that the Animal Corporation is after him because he knows secrets the company wants kept quiet.

Take the key to Room 5 and look for a poster hanging on the wall. Pull the poster down to reveal a hidden safe behind it. Use the key here to unlock the safe and reveal its contents.
Inside the safe, you'll find the follow items:
- A photo of Ratina : Ratthew's twin sister, who worked for the Animal Corporation before disappearing without any note or warning
- A suitcase marked "Top Secret"
- A short message inside the suitcase that reads: "The experiment was a success. The shadow now sees everything."
This connects directly to what Ratthew tells the player across his visits. He's been searching for Ratina since she vanished, and the contents of the safe strongly suggest her disappearance is related to whatever experiment the Animal Corporation was running.
