Chelsea were 'simply purring' after Sam Kerr scored their third goal of the afternoon to wrap up a convincing victory at Wembley.
Hayes' reference to cats, complete with purring noises, was likely a reference to Arsenal manager Jonas Eidevall's comments ahead of Sunday's final.
The Gunners boss had revealed his one superstition is to not let black cats cross his path before, saying: 'If Emma sees this she will probably buy a thousand black cats with the money Chelsea have and send them all over our training pitch.'
But black cats were the least of Eidevall's problems.
