How to unlock the Cat Door Courier achievement in Agent A: A puzzle in disguise - Definitive Guide
Before leaving a fish for the bird on the log, take one and put in through the cat door next to the evil lair for Onyx
Missable
You will get this in Chapter 5. After you've attached the net to the boat, you'll need to get a fish for Gunther. Once you get the fish, instead of giving it to the bird, take it back inside. At the lift, go to basement floor 1 (Floor -1). Interact with the kitty door on the left wall and place the fish inside of it. Onyx (the cat) will grab it, unlocking the trophy.
