This just might be almost too much concentrated cute for the Internet to handle.

Grumpy Cat and Lil Bub, probably the two biggest feline celebrities on the Web today, finally got the chance to meet Wednesday during the Internet Cat Festival in Minneapolis, Minn.

And the cats' owners caught their first encounter on Vine.

Tardar Sauce (Grumpy Cat's real name) and Lil Bub certainly have a lot in common. They each got a similar start on YouTube and they've each melted hearts and made their mark on the web; Tardar Sauce is soon to star in her own movie, and Lil Bub is the subject of a VICE documentary and will soon host her own Internet show.

So naturally, they must have much to talk about.

Tardar Sauce ended up winning the Golden Kitty at the Cat Festival, while Lil Bub grabbed a Hall of Fame award. Now that the festivities are winding down, they can get back to doing what they do best: being cats.

Although we hope to see a full-on collab video in the future, they're already Internet gold.
