CatCon LA, the first of its kind, debuts this weekend in downtown L.A.

Just like it sounds, it's a convention for cat lovers.

But unlike a cat show, it's not where the most pedigreed fluff gets crowned. Instead, think Comic-Con: This is strictly for cat fans and cat culture (and it's not BYOC, so don't bring your own cat).

"I expect this to be a really big event, a big gathering of the who's who of the industry," says Scott Stulen, creator of the Internet Cat Video Festival in Minneapolis.

It's also a rare chance for cat lovers to meet up.

"CatCon LA is like an oxymoron. It's like an introverts' conference," says Mike Bridavsky, who's the owner/manager of Internet star Lil BUB.

Here are some of the highlights:

• Lil BIB and Bridavsky are two of the headliners. On Sunday afternoon, they'll host "Lil BUB's Big Show Live," with special guest Jack McBrayer from "30 Rock."
• Mayim Bialik ("Big Bang Theory," "Blossom") introduces a talk on debunking the cat lady myth.
• "You Can Be a Cat Guy and Still be Cool," hosted by Keith Bowers, senior editor of Catster magazine (formerly known as Cat Fancy).
• Nearly 100 vendors offering cat-themed merch, including cat yoga mats, cat bow ties and more.
