This essay focuses on several categories of Wallace Stevens' use of animals in his poetry that is arguably posthumanist. It argues on the emotional ambivalence made by "Mountains Covered with Cats" which points out that animals are also living entities to experience and know with a mixture of positive and negative emotions. It cites Sigmund Freud's concept of ambivalence where he transcribe and reflect on the most well-known dream of a predatory animal in the modernist milieu.
