Ferretlike carnivore (8)
I believe the answer is:
mongoose
'ferretlike carnivore' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mongoose that I've seen before include "Animal of the civet family" , "Agile cat-like creature with long body and tail" , "Animal that kills snakes" , "Slayer of snakes" , "Carnivorous mammal that slays snakes" .)
