Grumpy Cat — one of the most beloved viral pets online — has died at age 7, and the internet will never be the same.

Grumpy's humans posted the news on social media Friday morning, and fans of the the unimpressed-looking feline, whose real name is Tardar Sauce, have been paying tribute ever since.

As internet lovers remember the joy this cat's grumpy little face brought to their lives, Mashable decided to dive into the archives and reminisce on all the memories we shared with Grumpy Cat over the years. There are A LOT.
