(NBC) - Internet celebrity Grumpy Cat, the face of countless memes, has died.

Her owners confirmed her death at the age of 7 via Twitter Friday.


The announcement on the Official Grumpy Cat Twitter account said she died on Thursday due to complications from a recent urinary tract infection.

Grumpy Cat, whose real name is Tardar Sauce, shot to fame in 2012 thanks for her permanent frown, apparently signaling displeasure at anything and everything. That scowl was later remixed and turned into thousands of memes on social media sites, with captions such as "I had fun once... it was awful."

The cat's unusual appearance was not in fact due to her temperament, but an unusual combination of an underbite and feline dwarfism, a form of genetic mutation.
