La gata perduda talks of the struggle of a neighbourhood which refuses to be manipulated, a united district which rebels against the powers that be and is itself a leading character in the opera, played by the joint local amateur choirs. Round about the Raval several characters appear who want to speculate and use it to promote their own interests: the Magnate, a man with a secret, surveys it from the upper part of the city and enlists the help of a healer, an architect and a detective to resolve the tangle of problems that are opposed to his interests.
The Cat undergoes a transformation in the course of the opera: she decides to be free, refuses to tolerate abuse, and embodies hope.
In this project more than ever before the Liceu acts as a mediator and La gata perduda is the ideal medium for giving diversity a voice. It is also a veritable path towards individual integration and development.
