Alert wild animal (5)
I believe the answer is:
ratel
'animal' is the definition.
(I've seen this before)
'alert wild' is the wordplay.
'wild' indicates anagramming the letters.
'alert' with letters rearranged gives 'RATEL'.
(Other definitions for ratel that I've seen before include "Badger-like animal" , "Animal of Africa and India - alert (anag)" , "predator" , "animal like a badger" , "One eats honey" .)
