Photo-Op: Sasha Grey, the keynote speaker at the 2010 AVN Adult Entertainment Expo, will unveil her sexy PETA ad immediately following her speech and will be available for interviews on the topic.

“I think spaying and neutering is incredibly important,” said Grey in an exclusive PETA interview. “[I]t keeps the animals out of the shelters and there’s too many unwanted animals out there already.”

Each year, up to 8 million dogs and cats are dumped at U.S. animal shelters, and about half of them must be euthanized because of a lack of suitable homes. Sasha urges all her fans to help curb the overpopulation crisis by spaying and neutering their dogs and cats to prevent pregnancies.
