ARIZONA, Calif. (KTVU) - She was a lovable feline with a sour disposition.
But the family of Grumpy Cat announced early Friday that she died earlier in the week at the age of 7.
Her family made the announcement in a social media post, "We are unimaginably heartbroken to announce the loss of our beloved Grumpy Cat.”
The post went on to say that she suffered complications from a recent urinary tract infection and passed away on May 14, "at home in the arms of her mommy, Tabitha."
Grumpy Cat, with her famous frown, became an internet sensation, that featured popular memes, toys, and calendars.
Her real name was "Tardar Sauce."
She became famous, when a photograph of her scowl was posted on Reddit and went viral.
Her crabby look was due to an underbite and feline dwarfism.
She and her owner, Tabatha Bundesen, went across the country, and appeared on KTVU's The Nine in 2016.
Grumpy Cat endorsed various products, and even starred in her own holiday special, Grumpy Cat's Worst Christmas Ever.
Her family wrote, "Besides being our baby and a cherished member of the family, Grumpy Cat has helped millions of people smile all around the world - even when times were tough. Her spirit will continue to live on through her fans everywhere."
