The mice at Rodent College are unhappy. The school is demanding an extra whisker off every animal's face. The mice gather, assemble a wheel so complex, even the Rodent Board of Directors can't quite jump aboard--it's too fast, too new. The High Queen wants to protect the health and security of her students. So when the group reaches its critical mass, she summons the cats, who pad back and forth, tails twitching. The mice spin faster and faster until the cats collectively hiss. The force of their breath knocks every last student down. Days later, the wheel still spins.
