Then Isla meets Poppy, a gorgeous cat in need of a loving home, and comes up with the perfect way to convince Mum. It's not long before Poppy has transformed life at the Palmers - everyone is happier, especially Gran, and even Isla's older sister Tilda admits she likes having Poppy around. But Poppy isn't the only one in need of a home and soon their house is full of cats. With Mum at her wits' end, Isla needs to come up with a plan and fast!
