In the four years since Simon's Cat first leapt in to our lives he has starred in more than 15 films, appeared in three best-selling books and has entertained and delighted millions of fans across the world. Along the way he has swotted flies, pulled down Christmas trees, and generally terrorised his long-suffering owner, Simon. And for the most part, he has had things his way. Until now. This year the nation's favourite cat faces up to his toughest challenge yet. With a new kitten in the house, a new girlfriend for Simon and endless new visitors to the garden, it is time to reassert his position - once and for all - as the undisputed Top Cat.
