Female squirrel (3)
I believe the answer is:
doe
'female squirrel' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for doe that I've seen before include "Mummy rabbit" , "Ode to a female deer" , "Ode to a female rabbit" , "Last FA Cup winners" , "A female deet" .)
