Catches performing seals (7)

I believe the answer is:

cachets

'seals' is the definition.
(cachet is a kind of seal)

'catches performing' is the wordplay.
'performing' indicates anagramming the letters.
'catches' anagrammed gives 'CACHETS'.

(Another definition for cachets that I've seen is " Seals".)

I've seen this clue in The Globe and Mail.
