An owl on the window

GrannyMo was reading in bed and Pat was curled up next to her, when there was a clatter. They didn't know what it was, Pat went to see if it was another cat, coming through the cat-flap to steal his food.

In the morning there was a mark on the window that showed that a bird had flown into it. We could see all the print of the wing feathers.
Dave took some photos - Granny went outside and held up a dark cloth so that it showed up better.
