We’ve always known those feline Internet sensations were destined for bigger things. Now, several of our favorites will appear in the documentary Lil Bub & Friendz, which debuts at the Tribeca Film Festival in New York City on April 18.

The 65-minute film, produced by VICE, follows the lovable perma-kitten Lil Bub as she and her owner, Mike Bridavsky, hit the road to meet other cat celebrities.

They include Grumpy Cat (aka Tardar Sauce), who always looks like she’s frowning; Keyboard Cat, known from a video shot in the 1980s that was posted on YouTube in 2007; and Nyan Cat, a cat animation with the body of a Pop-Tart who flies through space to a Japanese pop song.

And, on the sillier side, Lil Bub flies around in a spaceship.

“I got Bub because I thought she was amazing,” Bridavsky recalls in the documentary. “I took her home. I posted pictures of her on the Internet, and then that one photo just like blew up.”
