Cat visits round church a great deal (6)
I believe the answer is:
ocelot
'cat visits' is the definition.
'ocelot' can be an answer for 'cat' (I've seen this before). I'm not sure about the 'visits' bit.
'round church a great deal' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'church' becomes 'CE' (abbreviation for Church of England).
'a great deal' becomes 'lot' ('lot' can be a synonym of 'great deal').
'o'+'ce'+'lot'='OCELOT'
Can you help me to learn more?
(Other definitions for ocelot that I've seen before include "Feline mammal" , "Animal in the loo etc." , "Fur" , "Wildcat -- loo etc (anag)" , "Striped and spotted wildcat" .)
