Feed a pet sugar perhaps (9)
I believe the answer is:
pasturage
'feed' is the definition.
(I know that pasturage is a type of fodder)
'a pet sugar perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'a'+'pet'+'sugar'='apetsugar'
'apetsugar' anagrammed gives 'PASTURAGE'.
(Other definitions for pasturage that I've seen before include "Grassland" , "grazing land" .)
