As the irrepressible Foudini M. Cat regales us with his adventures, an exciting story unfolds. After his valiant but frail mother leaves him in search for food and never returns, the starving kitten is taken, hissing and spitting, to a frightening room with cages and men in white coats. Facing the specter of eternal sleep, the homeless cat is adopted by a woman he later calls "Warm." ("All cats like to make up strange names for things.")

From here Foudini enchants us with splendid tales of his unlikely but ultimately poignant friendship with Sam the Dog; their trips between Cold House in the city and Mouse House in the country; his mystical experiences with famous felines of the past; his near-death in a raging river that leads to a profound act of sacrifice; and his introduction to a silly young thing named Grace, which evolves into something completely unexpected.
