Spotted cat circle church group (6)
I believe the answer is:
ocelot
'spotted cat' is the definition.
(wild cat that has spots)
'circle church group' is the wordplay.
'circle' becomes 'O' (O is a circle).
'church' becomes 'CE' (abbreviation for Church of England).
'group' becomes 'lot'.
'o'+'ce'+'lot'='OCELOT'
(Other definitions for ocelot that I've seen before include "Type of American wildcat" , "Wildcat -- loo etc (anag)" , "American cat, like a small leopard" , "Feline of South and Central America" , "Wild cat, native to Central and South America - loo etc (anag)" .)
