The world-famous Grumpy Cat has passed away at the young age of seven. While her face was grumpy, she brought smiles to the faces of millions around the world through memes, public appearances and even a feature length film.

On her official twitter page (@RealGrumpyCat), the announcement was made as follows:

“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 too tough for her to overcome. She passed away peacefully…at home in the arms of her mommy, Tabatha.”

The reason for Grumpy Cat’s sour expression was due to dwarfism coupled with an underbite. But, this didn’t stop her from rising to stardom, her grumpy look accelerated it.

It all began in 2012 when the owner’s brother submitted a post of the cat on Reddit, claiming that the cat should win a “best cat on the internet” award. What followed was a year of intense fame and fortune as this humble house cat became the most famous house cat of all time. In 2013 alone, Grumpy Cat reportedly made millions of dollars, which included starring in her very own Lifetime movie: ‘Grumpy Cat’s Worst Christmas Ever.”

In 2015, Grumpy Cat was honored at Madame Tussauds in San Francisco, and even then US President Barack Obama did a Grumpy Cat impression when imitating his Republican opposition’s outlook on America.

To put one cat’s fame into context, today Grumpy Cat’s Facebook page has more than 8.5 million followers, 2.4 million followers on Instagram and over 250,000 YouTube subscribers. The legacy of Grumpy Cat will live on for ages to come as she now becomes one with the internet, never to be forgotten.

David Barritt, chief campaigner of animal welfare organization, Network for Animals (NFA), said: “We mourn the loss of this beautiful cat who brought smiles to millions of people worldwide. She will always be remembered.”

“Grumpy Cat proved that you can and should love all animals, even if they have physical deformities. She may have looked grumpy, but the world loved her all the more for it. We should do the same for all animals with all types of disabilities,” he said.
