Le Mystère des quinze chats
Twelve cats yesterday, fifteen today—yet no cat has arrived. Count the portraits and help Sacha and Inès uncover what changed at the shelter.

The story
A mystery to solve
Au refuge des Tilleuls, les chats ont un endroit où vivre en attendant une famille. Sacha y vient avec sa mère, qui aide la responsable, Amira. Son amie Inès les accompagne aujourd’hui. Les enfants préparent un panneau avec les portraits des chats. Amira leur montre le panneau d’hier : « Douze chats au refuge ». Puis elle dit : « Ce matin, nous en avons quinze. Pourtant, personne n’a amené de chat pendant la nuit, et aucun chat n’est parti. » Sacha regarde Inès. D’où viennent donc les trois chats de plus ?
