Snooki rocked Halloween eve in aRoma cat costume

Snooki looked absolutely purr-fect while signing copies of her new book Snooki: Confessions of a Guidette at Barnes & Noble in Las Vegas this Sunday. The Jersey Shore star rocked the signing on Halloween eve in a cat costume provided by Roma Costume. While at the bookstore, Snooki even ran into a fan dressed like herself and tweeted a picture posing with her own doppelgänger.
