Internet cats are a dime a dozen, but some actually become millionaires. Exhibit A: Grumpy Cat. This Siamese cat seemed to have a cursed start in life. An underbite and feline dwarfism resulted in a face that appeared to be perpetually frowning. And then one of her owners, youngChyrstal Bundesen, attempted to name her "Tartar Sauce" after the color of her whitish coat, but misspelled it as "Tardar Sauce." So Tardar she was, although many simply called her Grumpy Cat due to her sour puss [sources: Van Syckle, ABC 7].
Tardar's official owner, Chyrstal's mom, Tabatha Bundesen, started a Facebook page and Twitter account for Tardar. Suddenly she became an internet sensation, with millions of "likes" on Facebook and several hundred thousand Twitter followers. Tabatha joined forces with Ben Lashes, a California-based meme manager, to further Grumpy Cat's meteoric rise. (Lashes also reps "Keyboard Cat.")
Today Tardar's mug is on T-shirts. She's a spokes-cat for Friskies cat food, and she's written several books (the inaugural one, "Grumpy Cat: A Grumpy Book,"spent 10 weeks on The New York Times best-seller list). Grumpy Cat has raked in $100 million for Tabatha Bundesen, and Tardar is considered one of the most popular viral characters on the internet. Not bad for a dour cat with an underbite [sources: Van Syckle, CCTV, Wilson].
