Research overview: water economy and dietary moisture in desert-dwelling cats

Several small cats thrive in deserts, and this overview reviews how they manage water balance where free water is scarce. Desert cats such as the sand cat obtain much of their water from the bodies of their prey, relying on metabolic and dietary moisture rather than drinking, and they pair this with behaviour and physiology that limit water loss. This lets them persist far from open water. Researchers study water economy through field observation and physiological measurement. Why it matters: water balance is a central challenge of desert life, and the cat solution, extracting moisture from prey while minimising losses, exemplifies how a predator can colonise arid lands. It connects feline physiology to extreme environments and frames the sand cat and its relatives as models of mammalian adaptation to water scarcity.
