Doe or fawn (4)
I believe the answer is:
deer
I believe this clue is a double definition.
'doe' is the first definition.
(thesaurus)
'fawn' is the second definition.
(thesaurus)
(Other definitions for deer that I've seen before include "Source of venison" , "Hoofed grazing animal" , "Grazing animal(s)" , "Red, roe or fallow" , "Ruminant(s) -- breed of 13 down" .)
