Overfeeds essentially voracious male sheep (5)

I believe the answer is:

crams

I'm a little stuck... Click here to teach me more about this clue!

'overfeeds' is the definition.
The definition and answer can be both related to consumption as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?

'essentially voracious male sheep' is the wordplay.
'essentially' says to take the centre.
'male sheep' becomes 'rams' (I've seen this in another clue).
The central letter of 'voracious' is 'c'.
'c'+'rams'='CRAMS'

Can you help me to learn more?

I've seen this clue in The Telegraph.
