Having consumed the food, the animals, in turn, seem dizzy (7)
I believe the answer is:
stagger
'animals in turn seem dizzy' is the definition.
I can't judge whether this definition defines the answer.
'having consumed the food' is the wordplay.
'having consumed' means one lot of letters goes inside another.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'food' becomes 'sagger' (I am not sure about this - if you are sure you should believe this answer much more).
't' going within 'sagger' is 'STAGGER'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for stagger that I've seen before include "Reel - astound" , "bowl over" , "Surprise" , "Reel; amaze" , "Pitch" .)
