{As featured in Modern Cat magazine} Grumpy Cat fans rejoice! The internet-dominating frowny-faced feline that zinged her way through Twitter and Facebook now finally has a book out celebrating her eternal grumpiness. Likely to Grumpy Cat’s great displeasure, this collection of unsmiling photos matched with deadpan one-liners and quips is this year’s go-to gift pick for fans of the scowling internet sensation and/or silliness in general.
