This chapter tracks the figure of the rat across American short fiction, focusing in particular on H. P. Lovecraft’s “The Rats in the Walls” (1924), Ursula K. Le Guin’s “Mazes” (1975), and Karen Joy Fowler’s “Us” (2013). These stories illustrate powerful narrative effects that can be produced by constructing particular forms of animality, while also blurring, at times, the boundaries between what it means to be a human and what it means to be an animal. The chapter engages with the academic fields of human–animal studies, multispecies studies, and animality studies, exploring the short stories not only in relation to animal advocacy, but also problematic histories of animalizing certain human groups. Posthumanism cuts across these various fields, questioning constructions of the human as fundamentally different and superior to all other species on the planet. The chapter ultimately argues that some narrative techniques have more posthumanist potential than others.

What remains in life’s wake? Postapocalyptic literature long has imagined the end as a kind of beginning; someone or something always survives Armageddon, if only for a time. This is the postapocalyptic condition of possibility, enabling the genre’s cathected tropes of loss and redemption, regression and advance. Even when the survivors are not recognizably human—are androids, aliens, or nonhuman animals—“life” goes on. Engaging with a range of American fiction and nonfiction (from Ray Bradbury to Octavia Butler to Ray Kurzweil), this essay argues that what unites the posthuman and the postapocalyptic is, first, a shared, vitalistic investment in what might be called “life after death” and, second, a refusal or inability to narrate a final, lasting extinction. In H. P. Lovecraft’s radical take on Darwinian evolution, however, we can see the prospect of a posthuman sublime that never reconstitutes the autonomous subject. The chapter concludes with a brief meditation on the implications—metaphysical, biopolitical, and critical—of this self-alienation.
