It's spotted in a zoo (7)
I believe the answer is:
leopard
'it's spotted in a zoo' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leopard that I've seen before include "Animal -- per load (anag)" , "Large spotted cat" , "Spotted feline" , "Wild cat" , "Spotted big cat" .)
