NEW YORK (WLNY) — One of the biggest Internet sensations of all time, Grumpy Cat, stopped by The Couch on Friday to celebrate her second birthday.

Friskies Party Mix is throwing a big party for Grumpy Cat in the city on April 29, Grumpy Cat’s owner, Tabatha Bundesen, said.

Fans can enter for a chance to attend the party by taking an Instagram of themselves with their own cat while sporting their best grumpy face. The picture must be posted with the hashtag #1MMGrumpyFrowns before April 9.

Grumpy Cat, whose real name is Tardar Sauce, rose to fame after Tabatha’s brother posted a picture of the frowny feline on Reddit.

She is now the official “spokescat” for Friskies.
