In "The Cat Inside," William S. Burroughs reflects on the timeless behavior of cats, particularly their calm routine of grooming after eating. This ritual has been passed down through generations and illustrates a deep connection to their instincts. Cats seem to thrive on a balance between independence and domestication, highlighting their practical nature and preference for having humans supply their meals.

Burroughs further suggests that there is a historical divergence among felines; some embraced domestication while others maintained their wildness. This observation reveals the complexity of cats as both companions and independent creatures shaped by their evolutionary journey with humans.
