What is Grumpy Cat's real name?

The story behind the answer

Grumpy Cat’s real name is Tardar Sauce. “Grumpy Cat” was the internet nickname given to the feline whose permanently displeased expression, caused by feline dwarfism and an underbite, made her a viral sensation after photos hit Reddit in 2012. Her owner, Tabatha Bundesen, confirmed the given name “Tardar Sauce,” a playful misspelling of “tartar sauce” inspired by the cat’s mottled coloring.

To remember it, think: not just “Sauce,” but the full quirky condiment—Tartar—with a deliberate “d” twist: Tardar Sauce. Grumpy Cat became a pop-culture icon, starring in memes, merchandise, and even a TV movie, and she helped raise awareness that unusual-looking pets can be healthy and beloved.
