The star of South by Southwest Interactive? Tardar Sauce of course! The famously sour-faced kitty graced the Mashable booth at SXSW, receiving a reception worthy of the Beatles. Lines to see her stretched for three blocks, with fans waiting up to ninety minutes to get their photo taken with the cat. Tardar Sauce’s guardian, Tabatha Bundesen, sat close by to watch her cat, and worked with SXSW organizers to make sure that Tard’s schedule wasn’t too taxing. For the Grumpy One herself? Tard napped through the majority of her appearances – no doubt because she’s so OVER SXSW.
