This is Piper. She's a regular at the windowsill buffet. She's been paired up with a big lad of a dog fox, hanging out, grooming, and dancing...But vixens seek extra opportunities during their three days oestrus each year. And there a few handsome boys who now know she's very keen to get acquainted.

Last night I woke up to the sound of a vixen yelling. Blimey, I thought, it sounds like she's right outside the window. Because she was. Casually chomping peanuts while trilling and foghorn-loud shouting for a mate.
