Grumpy Cat, possibly the most popular Internet cat and protagonist of many of the first viral memes, died at the age of 7.

The family of the popular hairy pussycat announced his death on Twitter this Friday.

Grumpy Cat, whose real name was Tardar Sauce, had feline dwarfism. This, according to their owners , probably explained its particular facial features and small size.

He became an Internet celebrity in September 2012, when Tabatha’s brother, Bryan, published photos on Reddit that showed her in all her displeased glory.

The users in the platform reacted immediately by publishing innumerable variations using Photoshop, while the Imgur network reached 1,030,000 visits in its first 48 hours of posting the photo.

On the same day, the Bundesen family published video clips of Tardar Sauce on YouTube, which accumulated millions of visits.

Of the animal, shirts and calendars have been made, among many other merchandise with its image. She also had the movie “Grumpy Cat’s Worst Christmas Ever.”

Her popularity was sealed by his participation in South by Southwest Interactive (SXSW) Festival in Austin, Texas. People were in line for hours to take pictures with her, while she ignored most of her fans.
