Purr producer (3)
I believe the answer is:
cat
'purr producer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cat that I've seen before include "Lash < jazz fan" , "Animal (domesticated or wild)" , "Malicious gossip" , "eg Leopard" , "Animal - one with nine tails!" .)
