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

'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.

Can you help me to learn more?

(Another definition for heavy petting that I've seen is " Exploratory kissing and cuddling".)
