All rat locations (“Banned Footage Vol. 1” DLC)
Search the indicated locations in the “Bedroom” to find all three rats and get the “Ratcatcher” trophy. After Marguerite serves the second course, you must grab the fork she brings and get out of bed. This is a few minutes into the DLC after moving the bed for the first time. You also must collect the lantern and inspect all three rats.
1. Use the fork on the second dish she serves to reveal a rat in the food. This is after she takes away your soup and brings you another meal.
2. It is in the corner of the room near the picture frame. Use the lantern to inspect it.
3. It is in the locked side room. Use the following combination on the lock: Snake, Maple Leaf, Apple.
