The under belly of all cats. There are usually two distinct flaps between their back left and right legs. They are noticeable while strolling. They usually become larger as the cat gets older and/or fatter.
Caroline fed her young cat Seymour so frequently that his cat flaps eventually became so large that they dragged on the floor whilst walking.
