The fifth story in the New York Times bestselling Questioneers chapter book series following Ada Twist, Scientist and friends

Blue River Creek has a problem: there’s a pet thief on the loose! Or at least, Sofia and Iggy are convinced that there is once their pets go missing. But as a scientist, Ada knows it’s important not to jump to conclusions and to follow the facts.

How will they find out what really happened to the town’s pets? By using the scientific method, of course! Through making a hypothesis, collecting data, and experimentation, the Questioneers must find the missing animals before even more pets disappear!

From the creator of Can Cat and Bird Be Friends comes a delightful story featuring an adorable cat and an inquisitive dog. Dogs chase cats. Everyone knows this, especially cats. When Dog wants to chase Cat, he politely asks, "are you a cat?" To outrun and outsmart Dog, Cat pretends to be other animals that dogs wouldn't ordinarily want to chase. It's a masterful plan indeed. But when an unexpected creature walks by, it's impossible for Cat to play pretend for much longer. In a charming picture book filled with pleasing banter and hilarious quips, rising talent Coll Muir creates the perfect story about staying true to yourself. Perfect for fans of Jon Klassen's I Want My Hat Back, This Is Not My Hat, and We Found a Hat.
