Tracy Stewart, wife of former Daily Show host Jon Stewart, will be speaking at Z Space tonight at 7 p.m. about her new book, Do Unto Animals, as part of San Francisco Litquake.

Stewart, a former San Francisco resident, was a veterinary technician and founded a farm sanctuary for abused animals in New Jersey, where she and her husband live. Her book, part memoir and part how-to guide, details how people can more ethically interact with animals and offers “practical humane solutions to common animal-human conflicts,” according to the New York Times.

In any case, Stewart will be at 450 Florida Street tonight, and $25 secures a signed copy of her book and a chance to hear her speak with Litquake co-founder Jane Ganahl.

From the event’s page:

Longtime animal advocate Tracey Stewart, founder of a new farm sanctuary in New Jersey, imparts her wisdom about our four-legged friends. Did you know that pigs have superpowers? That cows swap babysitting duties? That there are scientific reasons why mutts make the best pets?

Join us for a good-humored evening with Tracey, who, along with her rather famous husband Jon, is now devoting her life to helping animals. Ticket price includes a signed copy of her new book, which she will personalize after the event. Tracey will be in conversation with Litquake co-founder (and fellow critter rescuer) Jane Ganahl.
