Bats rescued wolf (7)
I believe the answer is:
seducer
'wolf' is the definition.
(I've seen this before)
'bats rescued' is the wordplay.
'bats' indicates an anagram (slang for mad).
'rescued' with letters rearranged gives 'SEDUCER'.
(Other definitions for seducer that I've seen before include "One leading sexually astray" , "Philanderer" , "Rake" , "Rescued by sexual tempter" , "Rescued (anag) - Lothario" .)
