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

'fat cat' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'gerbil with ague shivering' is the wordplay.
'with' says to put letters next to each other.
'shivering' indicates anagramming the letters.
'gerbil'+'ague'='gerbilague'
'gerbilague' is an anagram of 'BIG-LEAGUER'.

'sees' acts as a link.
