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.
