I woke up to a strange sound. Eve was at the window hissing. Usually the window is open but because it was so cold, I had closed it. I pulled back the curtain. At first all I could see was that every time Eve hissed she fogged up the glass. It took me a minute to realize that on the other side of the glass was an all-white cat, sitting still as a statue, on the fire escape, just staring at her.
