Deeply personal feeling in fat cat, perhaps can end in sacking (5,7)
'deeply personal feeling' is the definition.
The definition suggests an adjective which matches the answer.
'fat cat perhaps can end in sacking' is the wordplay.
I cannot really see how this works, but
'fat' could be 'heavy' ('heavy' can be similar in meaning to 'fat') and 'heavy' is found within the answer.
'can' could be 'tin' ('tin' can be a synonym of 'can') and 'tin' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'in' acts as a link.
