The internet said goodbye in its own unique way.
Possibly the internet's most viral animal star, Grumpy Cat, passed away this week, and fans from all over are mourning the loss of the famous frowning feline. Since then, the Grumpy Cat Twitter account has amassed over 1.5 million followers and her Instagram account has over 2 million followers.
I can't even come to terms as I'm writing this that Grumpy cat passed away.
Some days are grumpier than others.
Christened Tardar Sauce, her mother was a Calico domestic shorthair cat named Callie and her father had grey and white strips.

In 2014, a report claimed that Grumpy Cat had a net worth of $100 million.
The mourning for Grumpy Cat will continue throughout the day, as many fondly remember the cat as the grumpy face of memes in the early 2010s.
Known for her grumpy expression, Tardar Sauce wasn't permanently perturbed in real life.
"She's super frisky, especially between 3 and 6 a.m. -when you're trying to get your deepest sleep, she's wanting to play", Bundesen said.
She is survived by her mom, Tabatha, and family members Bryan and Chyrstal.
Grumpy Cat, whose dwarfism and underbite give her the permanent frown she's famous for, became a superstar-turned-merchandising-machine after her owner Tabatha Bundesen first posted pictures of her in 2012.
Some stated that they were "heartbroken" at the loss, passing their sympathies on to the family at this hard time.
