In Little Cat Hide-and-Seek: A Playful Primer to Learn about Your Emotions, young children will learn to recognize and respond to emotions in themselves and others. The book introduces a range of emotions such as happy, angry, sleepy, anxious, and surprised. Each emotion is featured in a spread in the book, and each spread has a variety of illustrations with cats expressing different emotions. Children will match the emotion to the illustration that most closely represents it.

The book also offers children a chance to engage with their own emotions, asking such questions as "How about you? What makes you happy?" and "Whisper in Little Cat's ear the name of someone you love."

Little Cat is an appealing character that will appear in upcoming books about emotions published by Sounds True, including Little Anxious Cat and Little Angry Cat.
