In Richard Brautigan's work, there is an intriguing examination of the notion of intelligence being transferred through blood, using the concept of fleas as a metaphor. The passage suggests that fleas living on Siamese cats, perceived as more refined and intelligent creatures, would inherit superior qualities compared to those living on commonplace alley cats. This line of thought raises questions about inherited traits and the nature of intelligence.

By attributing intelligence to fleas based on their hosts, Brautigan prompts readers to reflect on how external influences shape understanding and perception. The playful yet thought-provoking assertion stands as a commentary on the interconnectedness of life forms and the arbitrary nature of what we consider intelligence, ultimately revealing deeper insights into expectation and identity.
