Charge pounds to see musteline mammal (5)
I believe the answer is:
ratel
'musteline mammal' is the definition.
(ratel is a kind of musteline mammal)
'charge pounds' is the wordplay.
'charge' becomes 'rate' (rate is a kind of charge).
'pounds' becomes 'l' (L can represent the monetary pound).
'rate'+'l'='RATEL'
'to see' is the link.
(Other definitions for ratel that I've seen before include "Animal of Africa and India - alert (anag)" , "Honey-badger" , "predator" , "one wanting honey" , "Mammal's" .)
