Flesh-eating mammal — one with fur, perhaps? (5)
I believe the answer is:
coati
'flesh-eating mammal' is the definition.
(I've seen this before)
'one with fur perhaps?' is the wordplay.
'one' becomes 'i' (roman numeral).
'with' says to put letters next to each other.
'fur perhaps?' becomes 'coat' (fur is a kind of coat).
'i' after 'coat' is 'COATI'.
(Other definitions for coati that I've seen before include "American denizen" , "Plantigrade carnivore" , "omnivore?" , "Flesh-eating mammal" , "beast" .)
