Pigeon flew into the window pane and then flew off, presumably nursing a headache.
Dcat jumped out of his skin, and then must have thought it was dd's new gold high heeled wedge sandals on the floor under the window that had made the noise. He warily approached them and hissed at them before plucking up the courage to stick out a paw and touch them. Apparently satisfied they were just shoes and not capable of independent movement, he then went to sleep!
