We were first introduced to 'Grumpy Cat' a few weeks back, when her hilarious scowl face went viral. Of course this begs the question, "why so grumpy lady kitty?" Maybe "Tard" (the cat's real name) likes being known as the cat with a permanent case of the kitty cat blues. Or maybe she's just ticked her owner keeps sticking a camera in her face. Either way, Tard has gained an impressive fan base.

Ever since her internet debut, the grouchy kitty has been meme-ified tons of times and has inspired costumes for Halloween. Now, all this fame has amounted into getting her very own website.

'Grumpy Cats' allows followers to keep up to date with all the crabby happenings of this seemingly down-in-the-dumps cat and -- perhaps the best part -- send in fan art of everyone's favorite sour feline.

Some are strange (like Grumpy Cat riding a giant bunny) but others are hilariously clever, like the submission that proves Tard IS Paul Ryan's doppelganger.
