This cat has definitely marked its territory in this mess
A cat rubs against people not only to be affectionate but also to mark its territory with scent glands around its face. The tail area and paws also carry the cat’s scent. It gets more fun with this photo, as it is almost impossible to spot where the cat is hiding, and the room not being in good shape isn’t helping.
You could use the cat’s scent to find it; if you can’t, try checking the picture again. Want a clue? Zoom in while checking all the boxes and items you see.
