Cats surrender late Perry power-play goal to snatch defeat from the jaws of victory.
Corey Perry scored the game-tying goal on a power play with 5.1 seconds left in regulation and the Anaheim Ducks went on to edge the Panthers 3-2 in a shootout after Chris Stewart's fourth-round conversion.
After a scoreless first period that saw the Ducks out-shoot the Cats 14-6, Orange County native Rocco Grimaldi opened the scoring at the 5:01 mark of the second.
Quinton Howden forced a turnover near the blue line and Derek MacKenzie picked up the biscuit and stormed in on Ducks starter Frederik Andersen.
