Born on April 4, 2012, Grumpy Cat was one of a litter of four kittens and had a form of dwarfism that made its face appear permanently grumpy. While the kitty was otherwise just a normal house cat, it only took one picture to change her life forever.

The kitty became an icon, with “Grumpy Cat” memes rocking the Internet as people created different iterations with ever-changing phrases and themes. Tardar Sauce appeared on many shows like ABC News’ Good Morning America and Anderson Live. It was the face of advertising campaigns for Friskies and General Mills’ Honey Nut Cheerios.

Once the news broke, thousands of people responded with their condolences as well as reactions and art pieces. “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,” Tabatha, Bryan, and Chrystal, the kitten’s closest family posted in a statement. “Her spirit will continue to live on through her fans everywhere,” they concluded.
