Charge pounds to see a musteline mammal (5)
I believe the answer is:
ratel
'musteline mammal' is the definition.
(I know that ratel is a type of musteline mammal)
'charge pounds' is the wordplay.
'charge' becomes 'rate' (rate is a kind of charge).
'pounds' becomes 'l' (currency sign).
'rate'+'l'='RATEL'
'to see a' acts as a link.
(Other definitions for ratel that I've seen before include "One eats honey" , "animal like a badger" , "Mammal's" , "Badger-like mammal" , "Animal of Africa and India - alert (anag)" .)
