Bernard Werber. The Cat's Tomorrow

Meet Bastet and Pythagoras, two amazing cats. Their lives are full of incredible adventures, and they are truly admirable.
Bastet, tired of her monotonous apartment life, dreams of understanding people and learning to communicate with them. Pythagoras lives in a laboratory, with a USB port on the top of his head that allows him to connect to a computer and thus gain knowledge about the world. Observing people, Bastet and Pythagoras decide it's time to save humanity from its vices and counter human aggression with the spiritual enlightenment of cats. But this task proves more difficult than it first seemed, forcing the cats to retreat and accept the rules of human civilization themselves. But perhaps it's not too late to change everything?
