Laboratory Cat Puzzle: Cabinet Code
Quick answer
Set the cabinet’s four dot-count buttons to 4 and 7 on the top row, then 3 and 5 on the bottom. The note orders the cats: black-and-white, white, brown, ginger. Their clues are 4 filled vials, 7 lit candles, 3 leafy plants and a clock showing 5.

Before you begin / items and clue route
Before you begin
- Unlock the Laboratory memory and move through its rooms until you can enter the folders/office room.
- Take the note about the cats from the folders on the table. It indicates the order of the four cats for the cabinet code.
Follow the clues
- 01
Record the order from the cat note
In the room with folders on the table, take the note showing the cats. Keep its pictured order in mind; the cabinet digits must follow that order rather than the order in which you happen to visit the rooms.
You’ll know it worked: You know the sequence in which to enter the four cat values.
- 02
Count the objects beside each cat
Visit the rooms with the cats and inspect the nearby objects: count 4 filled vials by the black-and-white cat; read 5 on the clock beside the orange/ginger cat; count 7 lit candles by the white cat; and count 3 leafy plants by the brown cat.
Compare the actual objects around each cat with the final four-button arrangement. Game image © Dark Dome; source capture by Play Games Wiki. View the source walkthrough ↗ You’ll know it worked: The four values are 4, 5, 7, and 3, assigned to their respective cats.
- 03
Enter the values in note order
Return to the cabinet in the white-cat room. Set its four dot-count controls to 4 at the top left, 7 at the top right, 3 at the bottom left and 5 at the bottom right. This follows the two rows of cats on the note.
You’ll know it worked: The cabinet opens; take the can and video camera.
- 04
Use the recorder and keep the sardines
Put the recorder on the tripod in the white-cat room. It still needs the night-vision lens from the fly chest and the room lights turned off. Keep the sardines for the crab: the can opener is inside the room behind the fingerprint door.
You’ll know it worked: The next camera task is prepared, and the fish is saved for the duck-radio sequence.
If you’re still stuck
I entered the four numbers in the order I found them and the cabinet stays locked.
Use the sequence printed on the cat note. The note controls the order; do not assume the physical room order is the code order.
What are the four cat clues?
The black-and-white cat is beside 4 filled vials; the orange/ginger cat has a clock showing 5; the white cat has 7 lit candles; and the brown cat has 3 leafy plants.
What is the final code?
Follow the order on the cat note. The completed entry is 47 across the top row and 35 across the bottom row.
