Animal with a black-tipped tail (5)
I believe the answer is:
stoat
'animal with a black-tipped tail' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stoat that I've seen before include "Eating rabbit, he" , "Weasel, ermine" , "Member of the weasel family" , "Ermine in summertime?" , "Short-tail weasel" .)
