This is the den where the apprentices eat, sleep and mingle. Most of the apprentices being energetic and restless even at night, the moss is scattered everywhere and it is rather messy in there. Just like all the other dens, the apprentice's den is in a tangle of reeds and ferns with a strong roof made from branches and feathers. The den is beside the medicine cat's den, therefore being across from the warrior's den and the nursery, as well as the river.
