Pets might, quite a lot (9)
I believe the answer is:
canoodles
'pets' is the definition.
(I've seen this before)
'might quite a lot' is the wordplay.
'might' becomes 'can'.
'quite a lot' becomes 'oodles' (I've seen this in another clue).
'can'+'oodles'='CANOODLES'
(Other definitions for canoodles that I've seen before include "Shares hugs and kisses" , "Kisses and cuddles" , "Pets" .)
