Similar to the medicine den, the apprentice's den is an abandoned burrow that warriors enlarged on the inside to accommodate the number of apprentices. A rock covers most of the entrance, but it's still possible to get inside, especially for cats the stereotypical size of apprentices. The entrance opens up directly to the clearing, so it's easy for apprentices to get bedding not only for themselves, but also for the elders and queens in the nursery. The inside is very dark, though, and apprentices have to be careful when walking around not to bump into walls or step on other cats' tails.
