Holly has a cat flap, but no cat. When one day a star fell from the sky, she made a wish, and CRASH! Tom arrived on her window sill. It was a mistake! cried Holly. I wished for a kitten. Tom was no kitten but a big scruffy cat with a crooked smile. Holly didnt want him, and shooed him away. But Tom was determined taht he should be her one and only wish cat.
