Ordinarily, the cat is a gentle and kind animal. The four cats in this story are not! On the contrary, they love to torment everyone who crosses their path. One morning, a mouse arrives in town, an animal known for its docility. But this mouse hates cats more than anything! For the first time, the cats find themselves bullied by someone meaner than them and decide to become kind. Kind, really? And can kindness overcome such an adversary? In a story shaped like a farce, Delphine Chedru joyfully deconstructs appearances through an adventure of the biter bit.
