Boo the tabby cat is born on a Lincolnshire farm and seems destined for a simple life. Everything changes when she's put up for adoption and taken in by Ellie Caldwell, an adventurous Cambridge graduate student who loves animals and is studying to become a wildlife conservationist.
Between lectures, Ellie heads to the countryside for camping trips, her Instagram-anointed 'adventure cat' in tow. On rocky trails, Boo discovers that, like Ellie, she has a passion for the natural world, and because she's able to communicate with all animals, she can relate their challenges back to Ellie. But there's a serious problem: whenever Boo tries to tell Ellie something, all Ellie hears is "Meow."
Can they work out a communication system, and in doing so, save endangered animals from harm while encouraging public support of nature and wildlife?
