A month ago, I saw a shadow on top of a wall. The sun was setting and all I could see was the silhouette of the little cat. I knew I had to capture this scene but I didn't have any camera on me at the moment, luckily I was able to take a few snapshots with my phone.
I only visualized the cat and the building on the right when composing this image, it wasn't until I copied the files to my computer that I saw the second cat resting in the background.
