It's a Kitty Collision as Grumpy Cat and Lil Bub Finally Meet

This is the one we've all been waiting for, friends. Grumpy Cat and Lil Bub, two of the biggest celebrities in the feline world, have finally met.

To be fair, there's no actual collision. Bub mainly wags her tongue around like a little weirdo, while Grumps just does what she does and appears generally unhappy. Watch the Vines below.

Fun fact: Grumpy Cat's actual name is Tardar Sauce. Not Tartar; Tardar. Go figure.
