Meet the airport therapy pig hogging all the attention at San Francisco International Airport

Lilou isn't your average pig.

She's spreading smiles to harried travelers everywhere as the world's first airport therapy pig. About once a month she heads to San Francisco International Airport to comfort stressed fliers, play with kids and generally make air travel a bit more fun.

Danilova reveals when Lilou will be coming to the airport on social media in advance of the visit. "It's kind of like a lottery," she said. "People get so excited if they're going to be traveling that day."

If you should find yourself at SFO, Lilou usually hangs out in terminal 3 on her volunteer days. "It's because of her hoofs, which we call her high heels," Danilova said. "She prefers the carpeting."
