I first heard the story told on Cbeebies story time. I re-enacted it much to my son's amusement and we bought the book at the earliest opportunity. Its a great book with a simply premise- several pets are sent by the zoo and all are unsuitable until the last one "he was perfect. I kept him". Its a lift the flap book with just enough text to keep their attention on each page. The illustrations are simple and bold and the book presents opportunities to talk about proportions and appearances and of course, to make funny animal noises. My son, in his enthusiasm, has wrecked the first one we bought him and we are going to have to buy a new one. That's how much he loves it. Since this book, he has really learnt to enjoy books as a one to one activity with me, which makes me really happy.
