Cats are territorial, which means they often stake out their turf and hang around to defend it from strangers. In Blockley, England, a cat lives next door to a Sainsbury supermarket. After the cat wandered into the store, security had the cat removed. Undeterred, the cat marched right back in and took a stand on top of the supermarket shelves.

Sainsbury claims the cat is a health and safety risk, but patrons and employees don’t seem to mind. When you look at the grumpy demeanor of the cat glaring back at you, you get the feeling that it knows its turf and it won’t let supermarket security personnel interfere with its territorial claims.
