Why do kangaroo rats produce little urine and dry droppings?

Kangaroo rats produce little urine and dry droppings as an adaptation to their arid desert habitats, where water is scarce. They have highly efficient kidneys that conserve water by concentrating urine, minimizing fluid loss. Additionally, their diet primarily consists of seeds, which contain moisture, further reducing their need for water. These adaptations enable them to thrive in environments with limited water availability.
