"Whatever you do, don't pat Grumpy Cat! You can maybe--if she's not looking--touch some of her stuff, like her milk bowl and cactus. But don't even try to pat her soft fur. That will just make Grumpy Cat even grumpier!"--Back cover.
"Pokey makes every effort to get Grumpy Cat to join in the Christmas spirit! Pokey wants to build a snow-cat together, go sledding, decorate the Christmas tree and bake cookies for Santa. Ultimately, Grumpy Cat wants to live in her wonderland of NO."--Back cover.
Illustrations and simple text describe different reasons for being grumpy, such as eating "grown-up" cereal, getting a boring birthday present, doing chores, and being touched by your brother or sister.
