Yip

The fox let out a yip in the night.

I've never hunted myself, but I understand that half the battle is being able to make noises like some jungle animal with dyspepsia, and I believe that Aunt Dahlia in her prime could lift fellow-members of the Quorn and Pytchley out of their saddles with a single yip, though separated from them by two ploughed fields and a spinney.
