At the foot of the village of Colicchio there is a mysterious laboratory carrying out secret experiments. No one knows what is really going on until an extraordinary fact is revealed that will change reality and reverse the roles of humans and animals. A cat, a monkey, a dog and a mouse lead the revolt. A story that knows how to touch people and make them think. An intense and fast-paced book. A manifesto that is not only antivivisectionist but also antispeciesist, it presents us with a truth too often ignored: revenge is never the right path to take.
