Resident Evil 7 Bedroom DLC – All Rat Locations

There are 3 rat locations in the bedroom DLC of Resident Evil 7. Finding all 3 rats unlocks the Ratcatcher trophy / achievement.
After marguerite serves the second course you must pick up the fork she brings you and get out of bed. This is a few minutes into the DLC after moving the bed for the first time (unmissable when you play through it).
You must also pick up the lantern and inspect all 3 rats.

1. Use the fork on the 2nd dish she serves to reveal a rat in the food. It’s after she takes away your soup and brings you another meal.
2. In the corner of the room near the picture frame. Use lantern to inspect.
3. In the locked side room. Use this combination on the lock: Snake – Maple Leaf – Apple.
