Unlimited legitimate retreats providing food fit for animals (6)
I believe the answer is:
silage
'fit for animals' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for silage that I've seen before include "Green fodder stored and fermented" , "Animal fodder harvested while green and partially fermented" , "Animal food" , "Fodder in store" , "Crop harvested for fodder" .)
