Pet selfies: yep, it's an actual thing. And while celebs like Marc Jacobs, Lauren Conrad, and Zooey Deschanel certainly didn't start the trend, they do have some of the most stylish pets we could find on Instagram -- which is how they came to be nominated in that very-named category in InStyle's first-ever Social Media Awards. Check out the nominees (which also include the adorable pups of Amanda Seyfried and Mariah Carey) and vote for your favorite by this Sunday, September 15 at 11:59 p.m. ET, when polls close. Be sure to hashtag your support using #InStyleSMAs, and look for the winner in December on InStyle.com and in that month's issue.
