What is the source of nearly all the water required for the kangaroo mouse's survival?

Answer

Moisture derived metabolically from the seeds they consume

Kangaroo mice can subsist entirely on the moisture released during the metabolic breakdown of the dry seeds they eat, a process yielding metabolic water, allowing them near-total independence from liquid water.
