"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," it read.
"Besides being our baby and a cherished member of the family, Grumpy Cat has helped millions of people smile around the world – even when times were tough," the statement continue.
"Her spirit will continue to live on through her fans everywhere."
Grumpy Cat, her real name being Tardar Sauce, rose to prominence back in 2012 when a photo of her was posted to the r/pics subreddit. The real magic came next once the Internet does what it does best, make memes. From there Grumpy Cat's rocket to stardom was just taking off.
"It was suggested that the original photo was photoshopped, so we posted a few videos on YouTube," said the owners on the official Grumpy Cat website.
