The mixed-breed “encountered complications from a recent urinary tract infection that unfortunately became too tough for her to overcome,” the statement read.
“She passed away peacefully,” it added, “at home in the arms of her mommy, Tabatha.”
The family from Morristown, Arizona, noted how Grumpy Cat, whose real name is Tardar Sauce, had “helped millions of people smile all around the world — even when times were tough.”
It vowed that “her spirit will continue to live on through her fans everywhere.”
Tributes poured in on Twitter, where fans said they were “heartbroken” by the news.
