I just came home with DS from school to hear an almighty clatter at the window - saw a tomcat from next door trying to get in (or get out, perhaps?) - the noise was from the wooden blind clattering
I have now booked her in to be spayed - just incase!
Poor Mitten is terrified now though - she won't come in the front room or go to her perch near the window (the back of the armchair)
