Lily and her family are going for a walk with their dog, Hugo, when Hugo sniffs out an amazing secret. A litter of kittens have been abandoned in the woods! Without their mother the kittens may not survive the night, so Lily’s family take them in. Lily loves caring for the kittens – and even Hugo does his best to protect the new arrivals. But her little sister is afraid of cats and Lily knows all along that she won’t be able to keep any of the kittens – even her favourite, the adorable Stanley.
