For carnivore, flesh: let me see a kilo being eaten (7)
I believe the answer is:
meerkat
'for carnivore' is the definition.
(meerkat is a kind of carnivore)
'flesh let me see a kilo being eaten' is the wordplay.
'flesh' becomes 'meat' (flesh is meat).
'let me see' becomes 'er' (both might be said when hesitating).
'a kilo' becomes 'k' (phonetic alphabet: alpha, bravo, charlie etc.).
'being eaten' means one lot of letters goes inside another.
'er'+'k'='erk'
'meat' placed around 'erk' is 'MEERKAT'.
(Other definitions for meerkat that I've seen before include "Tee mark, oddly, on the four-toed catlike animal" , "Small southern African mongoose" , "South African mammal" , "Mongoose-like animal" , "Small South American cat-like animal, has four toes" .)
