You've probably heard this before; how the internet is like Ancient Egypt, and people write on walls and worship cats. Because that's what we've been doing in 2014. Liking cute cat pictures and going gaga about internet cat celebrities who've risen from hilarious memes to endorse products, star in movies and travel the world.

5. Nala Cat

Nala became famous when her owners shared images of her with an apparent shocked expression (her mouth was just open, really) and in cute costumes and funny poses. She has her own website which sells all kinds of merchandise branded with more of her wacky expressions.

6. Snoopy

Remember that cat in memes with her face sticking out through a piece of bread? She's officially the cutest cat online!
