The dynamic Cedar Falls family behind the social media accounts "I've Pet That Dog" and "I've Pet That Cat" — as well as the book, "Pet That Dog!" — are at it again. Next summer, Rachel Braunigan and her son, 11-year-old Nigel Kidd, will release the family's second book, a companion to "Pet That Dog!" called "Pet That Cat!" The new book will feature quizzes, cat facts — which Braunigan said are her son's specialty — as well as tips on how to pet and care for cats. Like "Pet That Dog!", written by Braunigan and Nigel's older brother, Gideon, it will be published by Quirk Books.
