As of this past weekend, cat conventions are officially a thing. The Los Angeles Times reports that Downtown LA's The REEF played host to the first annual CatConLA, where an estimated 10,000 attendees spent Saturday and Sunday hitting up cat-themed panels, meeting Internet-famous cats, and hazzing cheezburgers like they never could haz before. Check out photos from the event below. (And for more cat photos, check out this photo of a cat that's allegedly the oldest photo of a cat ever.)
