What organ helps Kangaroo Rats conserve water?

Kangaroo rats have highly specialized kidneys that play a crucial role in conserving water. Their kidneys are capable of producing highly concentrated urine, allowing them to retain as much water as possible while excreting waste. This adaptation is essential for their survival in arid environments, where water is scarce. Additionally, they have a minimal need for drinking water, deriving moisture primarily from the seeds they consume.
