They obtain moisture from their food.
Most desert animals spend a significant amount of time underground and are primarily active at night, which allows them to avoid overheating. They require moisture infrequently and in small amounts. They extract it from the vegetation they feed on, such as fleshy cacti.
Sand rats living in desert conditions obtain enough liquid even from grains and roots. The food of these rodents, stored in their burrows, absorbs moisture from the air they exhale.
Sand rats can live their entire lives without quenching their thirst with water. In general, in areas where water sources are absent, only a limited number of mammal species are found.
