Liquid a pet once upset, covering jotter (4-3)

I believe the answer is:

note-pad

'jotter' is the definition.

'liquid a pet once upset covering' is the wordplay.
'covering' indicates a hidden word.
'upset' says the letters should be written in reverse.
'dapeton' is hidden within 'liquid a pet once'.
'dapeton' written backwards gives 'NOTE-PAD'.

I've seen this clue in The Telegraph.
