Mother rabbits like to keep their kits underground in their hand-created “warehouse” aka warren. Typically the newborn kits are surrounded by fur or food materials. Soon-to-be mother rabbits usually pull their fur to keep their upcoming babies warm. Since these small newborns are buried in soil by their mother for their safety, the dirt is loose right on top of them, and between the dirt, the air pockets are enough. Mother rabbits usually cover their holes with a thin layer of soil or the nest created by straws or hay, to keep the predators away. Moreover, the mother comes to check on them from time to time, so she digs up again for feeding.
