Staggered by Edward eating carnivorous animal (8)

I believe the answer is:
tottered
'staggered' is the definition.
(I've seen this in another clue)
'edward eating carnivorous animal' is the wordplay.
'edward' becomes 'ted'.
'eating' indicates putting letters inside.
'carnivorous animal' becomes 'otter' (I've seen this before. I am not sure about the 'carnivorous' bit.).
'ted' placed around 'otter' is 'TOTTERED'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for tottered that I've seen before include "Ruinous" , "Swayed and threatened to fall" , "Walked very unsteadily or shakily" .)
