This week, I figured I would combine two things that are loved by both me and the internet as a whole: cats and memes.

So, without further ado, here is a collection of cat memes that have captured our hearts and changed the way we look at the internet.

1. Grumpy Cat

Single Dad Laughing

Grumpy Cat is such a classic meme. Known by his loved ones as Tardar Sauce, Grumpy Cat’s adorably irritable face makes anyone’s heart warm and fuzzy (much like a cat).

2. Keyboard Cat

Know Your Meme

Keyboard Cat is for those who love music and cats. Watching this little orange fluffball go hard on the keys is bound to make any music lover sing with joy.

3. Long Cat

Know Your Meme

Why is this cat so long? It’s okay, buddy, you’re still cute.

4. Fire Cat

Meme Center

Listen, I love cats, but this cat scares me. He looks like he just killed a whole bunch of people, and it’s really unsettling.

5. Science Cat

Meme Super

As someone who isn’t crazy about science, I love Science Cat. He takes something I’m not crazy about and makes it fun. Good for you, Science Cat. Good for you.

6. Business Cat

Know Your Meme

There seems to be a cat for every mood—happy, sad, angry, scared—but Business Cat encompasses that once in a blue moon feeling where you just need to get things done. If anything, Business Cat is a motivator.

Honorable Mention: Nyan Cat

Mashable

Nyan Cat doesn’t make the cut only because he’s not an actual cat. However, his classic yet highly annoying tune will never get un-stuck from our heads. (You’re thinking about it right now, aren’t you? Me too. If you want to listen to it for an incredibly long time, click here.)
