In the book Burroughs, a noted lover of cats, reminisces about the many cats in his life. Gysin, a frequent collaborator with Burroughs dating back to the early 1960s, died in 1986, making this possibly the last work he did with Burroughs. Gysin is also referenced by name in the text.

Burroughs reads excerpts from the novella, "Kill the Badger!" and "Warning to Young Couples", on the albums Dead City Radio (1990) and Spare Ass Annie and Other Tales (1993).
