Animal resembling the shrew? (3)
I believe the answer is:
cat
I believe this clue is a double definition.
'animal' is the first definition.
(I've seen this before)
'the shrew?' is the second definition.
(thesaurus)
'resembling' acts as a link.
(Other definitions for cat that I've seen before include "Animal; converter; boat" , "Carnivore; whip" , "An old whip with nine tails" , "Pussy" , "Lash < jazz fan" .)
