The most famous cat in the world has sadly died. Grumpy Cat, the star of one of the first viral memes, has died at age 7.
The famously unhappy cat's family announced her death on Twitter on Friday.
"We are unimaginably heartbroken to announce the loss of our beloved Grumpy Cat," Tabatha Bundesen, Grumpy Cat's owner, said.
"Despite care from top professionals, as well as from her very loving family, Grumpy encountered complications from a recent urinary tract infection that unfortunately became too tough for her to overcome. She passed away peacefully on the morning of Tuesday, May 14, at home in the arms of her mommy, Tabatha," read the statement.
"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," Bundesen, who lives in Morristown Arizona, wrote.
Grumpy Cat, whose real name Tardar Sauce, wasn't actually sad all the time. The cat had feline dwarfism, which likely accounted for her distinctive facial features.
Her rise to fame happened in September 2012 when Tabatha's brother Bryan posted photos on Reddit. Users on the platform immediately reacted by posting creating memes of the pictures.
On the same day, the Bundesen family posted video clips of Tardar Sauce on YouTube, which racked up millions of views.
"It was suggested that the original photo was Photoshopped, so we posted a few videos on YouTube," the owners said on the official Grumpy Cat website.
That year, she participated in the Southwest Interactive (SXSW) festival in Austin, Texas, which cemented her popularity. People stood in line for hours to get their pictures taken with Grumpy Cat.
At the time of her death, Grumpy Cat had multiple advertising deals, 1.5 million followers on Twitter, 2.4 million on Instagram, and 8.5 million on Facebook.
