Tardar Sauce, the grumpiest feline to strike the Internet in 2012 owes her success to Reddit. Her pictures went viral on the site. She has retained Marty Singer, one of Hollywood’s most notable litigators. The cat and her owners have initiated an intellectual property dispute against Grenade Beverage, a company that is producing an iced coffee brand marketed as “Grumpy Cat Grumppuccino”. On December 11, Singer filed a lawsuit on behalf of Grumpy Cat Limited in California federal court. “Ironically, while the world-famous feline Grumpy Cat and her valuable brand are most often invoked in a tongue-and-cheek fashion, Defendants’ despicable misconduct here has actually given Grumpy Cat and her owners something to be grumpy about,” the lawsuit’s first line reads.
