'being catty' is the definition.
(I've seen this in another clue)

'feeling no end upset' is the wordplay.
'no end' means to remove the last letter.
'upset' indicates an anagram.
'feeling' with its last letter taken away is 'feelin'.
'feelin' anagrammed gives 'FELINE'.

'could get you' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
