Below are the collectibles you can obtain in Chapter 11 of Stray!
B-12 Memory
Progress through the level until you’re reunited with both Clementine and B-12. Shortly afterwards, you’ll have to trap a drone into a cell. After doing this, Clementine will open the gate. Just after the gate the memory can be found on the wall to the right.
Scratch
Immediately after the above memory, you’ll have to trap 2 drones into a cell. Do so then Clementine will open a door allowing you to proceed forward. In the next area, you’ll end up in a courtyard with a tree.
Use the tree as a scratching post.
