Female animal, ravenous, emptied containers (5)
I believe the answer is:
ewers
'containers' is the definition.
(ewer is a kind of container)
'female animal ravenous emptied' is the wordplay.
'female animal' becomes 'ewe' (I've seen this before).
'emptied' means to remove the middle letters.
'ravenous' with its centre taken out is 'rs'.
'ewe'+'rs'='EWERS'
(Other definitions for ewers that I've seen before include "Vessels with handle and spout" , "Water jugs" , "Vase-shaped jugs" , "containers" , "Pitchers" .)
