Ogre's cat plays with snail (8)
I believe the answer is:
escargot
'snail' is the definition.
(escargot means an edible snail)
'ogre's cat plays' is the wordplay.
'plays' is an anagram indicator.
'ogres'+'cat'='ogrescat'
'ogrescat' with letters rearranged gives 'ESCARGOT'.
'with' is the link.
(Other definitions for escargot that I've seen before include "mollusc, from Paris" , "A dish of cooked land snails" , "Edible snail (from Fr.)" , "slow food?" , "Hardly fast food" .)
