It's been reported that the inspiration behind one of the earliest internet memes passed away earlier this week, as Grumpy Cat has reportedly died at the age of 7. 

Grumpy Cat became an internet sensation went a photo of her trademarked grumpy face went viral on Reddit back in 2012, where since that time she's garnered 8.5 million Facebook fans, 2.4 million followers on Instagram, 1.5 million followers on Twitter, and more than 260,000 subscribers on YouTube. 

Additionally, the mixed-breed feline became the subject of book deals, Honey Nut Cheerios commercials, and even her own movie on Lifetime during her rise to fame. 

"Some days are grumpier than others," Grumpy Cat's publicist said in a statement this morning, as it was noted that Grumpy, whose real name is Tardar Sauce, died peacefully after succumbing to complications from a urinary tract infection. 

"Grumpy Cat has helped millions of people smile all around the world," the statement read further, "even when times were tough."
