The cat with a permanent frown had millions of followers and was so famous that her owner quit her waitressing job.
Sky News reports that Grumpy Cat (real name Tardar Sauce) passed away on Tuesday but her owners announced the death on Twitter on Friday 12th July.
They said: “We are unimaginably heartbroken to announce the loss of our beloved Grumpy Cat.
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 to tough for her to overcome. “She passed away peacefully…at home in the arms of her mommy, Tabatha.”
Grumpy Cat and her permanent frown became a social media sensation after her picture was posted online in 2012.
Last year she won a $710,000 (£556,000) payout following a lawsuit against a coffee company that used her image beyond the limits of a contract they had signed with the cat’s owners.
