Cat memes took over the Web and now they’re taking over the Tribeca Film Festival with the new documentary “Lil Bub & Friendz.”

Premiering April 18, Lil Bub is the star of the Vice-made film, but several of her “friendz,” including Grumpy Cat, Keyboard Cat and Nyan cat also make appearances.

Mike Bridaysky adopted Lil Bub, a “permakitten” that will stay kitten-size her entire life, from a family who was having a hard time finding a home for her. The runt of the litter, Lil Bub was healthy, but unique.

She’s a dwarf, so her limbs are disproportionately small and she has a short, serpent-like body. Her lower jaw is shorter than her top jaw, and her teeth never grew in, which is why her tongue usually hangs out.

Lil Bub can’t run or walk well, but Bridaysky says she waddles just fine. She also can’t jump, but because she’s polydactyl, Lil Bub has an extra toe on each paw and 22 claws to help her climb.

Bridaysky calls her “one of nature’s happy accidents” and says there’s something very special about this feline. The Internet agrees.

The first photo he shared of Lil Bub went viral, and today the cat has more than 100,000 Facebook fans, as well as more than 8,000 Twitter followers — not to mention her very own documentary.

“Lil Bub & Friendz” shows what life is like for a famous feline and her owner, answering questions about how Bridaysky manages the cat’s career and how he responds to allegations that he’s exploiting his pet.

But the film makes it clear that Lil Bub is first and foremost a beloved pet. In the middle of the movie, Lil Bub gets sick and veterinarians aren’t sure how to help her. When Bridaysky comes home and discovers that she’s not in her usual spot, he fears the worst.

“There was a very scary week there. It was horrible. I actually thought it might be the end of Bub,” he told Time. “A lot of what was going through my mind was how much she means to so many people. I’ve gotten myself into a situation where even if I do have to put her down, I’m going to get blamed for it.

Luckily, Bub is now happy and healthy and ready to promote her film.

Laura Moss writes about a variety of topics with a focus on animals, science, language and culture. But she mostly writes about cats.
