'finally agrees' is the definition.
I can't judge whether this definition defines the answer.

'doctor vaccinates cat abandoned' is the wordplay.
'doctor' indicates anagramming the letters.
'abandoned' is a deletion indicator.
'vaccinates' with 'cat' taken out is 'vcinaes'.
'vcinaes' with letters rearranged gives 'CAVES IN'.

'and' is the link.
