'it's not eating worms' is the definition.
I can't tell whether this definition defines the answer.

'i get a raven trained' is the wordplay.
'trained' indicates an anagram (to train can mean to grow something into a shape).
'i'+'get'+'a'+'raven'='igetaraven'
'igetaraven' is an anagram of 'VEGETARIAN'.

'so' is the link.
