One evening Dave and I were sitting & talking in the master bedroom (with our bedroom door shut) when all of a sudden we heard a strange thumping noise coming from our master bathroom. Come to find out Ms. Kitty had snuck in, opened the cabinet under the bathroom sink, got inside it and closed it behind her! I took this picture only after opening the cabinet door. Cassie had already warned us that her cat knew how to open/close doors.
