In a very fine house, on a very grand street, lived the tiniest mouse you could possibly meet. The youngest of twelve, he was timid and slight, but he was always, ALWAYS very polite.
When tiny Horatio Squeak is invited to a mysterious party at the top of the stairs, he finds himself in the unexpected company of kittens with dreadfully bright teeth and dreadfully sharp claws. Despite their intimidating appearance, the kittens are welcoming hosts who seem to enjoy Horatio's company. But when they spot a bird in the window, they cannot resist the urge to catch it. As Horatio watches on with horror, he finds the courage to speak out and save the scared bird. With his newfound bravery, Horatio returns home feeling stronger and not nearly so small.
