This Saturday cat lovers will descend on San Francisco for the First Annual Intergalactic Feline Film & Video Festival for Humans. It should be a meow-valous time.The festival will share the best feline films, both well-known and new, and the event's programs include an opening ceremony featuring Japanese cat videos, a "brief history of Internet cat videos," a memorium award for felines past, and musical accompaniment to a 1944 film about cats. The festival will also include an award ceremony for Lil Bub, whose overly large and permanent sticking-out-tongue look has made her perhaps one of the Internet's most famous cats and has now apparently earned her the award for "Outstanding Achievement in Cat." Now that's a hard award to get. Due to the fact there will be so many cat videos in one day, it's been referred to as "a 2-week film festival in the span of 12 hours," and the Saturday festival will take place at the Roxie Theater. The opening ceremony (starring Lil Bub) will be at noon, the centerpiece event takes place at 4 p.m., and the closing night event (involving dancing and cocktails) begins at 8 p.m. In addition to Lil Bub, the website hints that there may be more feline Internet sensations present, although it also requests that guests don't bring their cats into the theater. Tickets are $12 per program or $30 for the whole day. Check out the event's trailer below.
