Patsy's son caught two animals (9)
I believe the answer is:
scapegoat
'patsy's' is the definition.
(I've seen this before)
'son caught two animals' is the wordplay.
'two animals' means two replacements for 'animal'.
'son' becomes 's' (genealogical abbreviation for son).
'caught' becomes 'c' (cricket abbreviation).
'animal' becomes 'ape'.
'animal' becomes 'goat' (I've seen this before).
's'+'c'+'ape'+'goat'='SCAPEGOAT'
(Other definitions for scapegoat that I've seen before include "One blamed for others' mistakes" , "Fall guy" , "One blamed for others' wrongdoings" , "Can carrier" , "Someone to blame" .)
