'pets?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'bye-bye old sue's poorly' is the wordplay.
'poorly' indicates an anagram (a poor spelling).
'bye'+'bye'+'old'+'sue'='byebyeoldsue'
'byebyeoldsue' with letters rearranged gives 'BLUE-EYED BOYS'.
