This chapter analyzes the role of animals in Matéi Visniec’s novel Syndrome de panique dans la Ville lumière, showing how they function both as ethical and poetic agents within a dystopian narrative. Through the figures of a cat and a dog, Visniec destabilizes anthropocentric perspectives, granting animals autonomy, emotions, and narrative voices. Their stories reflect central concerns of contemporary animal studies, such as the redefinition of human-animal boundaries, the critique of speciesism, and the search for new axiologies capable of overcoming Cartesian dualisms. The novel stages animals as vectors of ecological awareness and symbolic resistance against modern technicist obsessions. Literature thus becomes a privileged space for rethinking interspecies relations and for preserving endangered forms of life.
