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.

Our Memorial Day was spent in Los Angeles, advocating for mental health awareness and bringing many therapeutic smiles to adults and kids! It was at a very well-organized event for @werise_la project of LA’s Department of Mental Health on a cool rooftop downtown. My fellow 🐶 therapists @deafdal @maggieandrossi @gigimakesmesmile @mistricks associated with @petsonq didn’t quite know what to think of me. @mistricks and @deafdal were especially hilariously curious 🙈😂🐷 I guess they don’t see a city pig every day. But everyone was awesome, warm and kind. I had a LOT of fun on this road trip. How was your weekend? 😘💕🐷 - - #sfpig #lilouthepig #lilou #therapypig #petpig #citypig #pigsofinstagram @buzzfeedanimals @theellenshow #buzzfeedanimals #thedodo #smileambassador #pigambassador #therapyanimal #bayareabuzz #cityofangels @cutepetclub @peopletv @9gag @overheardsanfrancisco @people @onlyinsf @overheardla #animalassistedtherapy #travelblogger #spreadlove #spreadjoy #socal #dressedtoimpress #lovemyjob #communityservice #mentalhealthawareness #mentalhealth #humananimalbond #tbt #californiadreaming #mentalhealthawarenessmonth

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."
