Amy, Molly, Lily, Ruby, Ella and Mia meet whilst choosing their adorable new kittens from a litter born at a local farm. The girls quickly become firm friends and form Kitten Club so that they can get together and swap stories about their gorgeous new kittens. Molly's house is already full of pets - two lively dogs, a hamster and old cat called Humbug - but Molly's sure there's room for Smoky, her beautiful fluffy kitten. Smoky just wants to have fun and her lively games quickly get her into trouble with the other animals, especially Humbug. Can Molly help Smoky to make friends...?
