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 an anagram.
'alert' anagrammed 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" .)
