¡Qué hambre tiene Gato! Se comería... un pastel de arándanos... o una magdalena... ¿o quizás la rosquilla? ¿Y un pastel de chocolate? Un momento! ¿Quién se ha comido el pastel de Gato?

Federico the cat travels from roof to roof to visit all his families; among them are Tadeo, who lives with his grandparents, Ana and her two moms, and Virginia with her father and mother. They are different families and Federico loves them all equally.
