Internet meme Grumpy Cat to star in Friskies adverts Internet celebrity Grumpy Cat, the face that launched a thousand memes, makes a surprise appearance on Friskies Will Kitty Play With It? SOCIAL MEDIA meme Grumpy Cat is laughing all the way to the bank after 'selling out' and appearing in a series of cat food ads. The sourpuss, whose real name is Tartare Sauce, was signed up by United States cat food company Friskies earlier this month. The first of the series of adverts has now hit the airwaves. The dour-faced cat became famous after appearing in a slew of sharp-witted and cutting internet comments, mostly playing off her expression. At a recent public appearance, fans waited in lines for up to three blocks in length for a glimpse of the curmudgeonly kitty. The morbid moggy stars in Will Kitty Play With It?, part of a celebrity-filled series of commercials done in the style of a game show. Grumpy Cat will no doubt revel in the scandal of selling out to corporate interests, though it is yet to be seen if her cutting internet comments will be curtailed. The foul-mouthed kitty's rapid rise to fame and fortune even resulted in an interview with Forbes magazine.
