Sentence:  I prefer to use <WSD>Jills</WSD> on my ferreting jobs. All are fitted with transmitter collars, and I would never work a ferret without one. That said, I always make sure I have a large Hob ferret with me because sometimes he will shift stubborn rabbits where the <WSD>Jills</WSD> have failed. 
Meaning of the word marked with <WSD> tags:  A female ferret.
