The internet suffered a great loss today as Grumpy Cat, its most famous cat to date, is dead at the age of 7.

CNN reports that Grumpy Cat’s owner, Tabatha Bundesen, announced the sad news on Twitter. The feline was suffering from medical complications and sadly died on Tuesday.

Grumpy Cat, real name Tardar Sauce, became an internet sensation when Bundesen’s brother posted a photo of her on reddit in September of 2012. Grumpy Cat’s distinct features were attributed to feline dwarfism.

The photo reached over a million views within the first 48 hours of being posted. After countless memes were born, Grumpy Cat lent her likeness to cat food, shoes, coffee and more, cementing Grumpy Cat’s legacy as a pop culture icon. She also appeared on television shows and drew a massive crowd at SXSW in 2013.

You will be missed, Grumpy Cat.
