Delip, a Hripirt immigration screener stationed in New York City, attended a Broadway performance of Cats to help her better understand the human mind. The play featured humans dressed up as small domesticated beasts, cavorting in a heap of garbage. The play was not simply animal-mimicry, as the actors playing beasts represented human characteristics, such as vanity and gluttony. From a Hripirt frame of reference, the allegory was similar to the morality plays of Tipli the Humble, although the concept of sentient actors playing beasts who behave like the actors' own kind had no precedent.
The beasts paraded before their Elder, hoping to be chosen to ascend to animal paradise, with their characteristics determining which one was to be selected. This amused Delip, for it seemed similar to her job of screening Earth candidates for work visa applications on Hripirt. Thus, Delip later told Mullnor and Bingokk that the play amused her, though not for the same reasons that the humans liked it.
While Cats is very clearly described, the story does not state its title nor the names of any characters.
