At Animal Ark, Mandy Hope helps her parents treat animals of all shapes and sizes. Even outside the clinic, Mandy can't resist helping any animal in need. A stray tabby cat has turned up in Welford and Mandy is worried. The poor cat is about to have kittens and she has no one to look after her. Bill Ward, the mailman, comes to the rescue, allowing her to live in his garden shed. But the tabby isn't the only cat in the neighborhood having kittens...and some of the kittens need extra-special care. Will Mandy be able to help the kittens and their mothers?.
