This is a very spacious and comfortable cave, more than den. It stretched many tail lengths back, and its roof is very high.
The floor is covered in clean sand. It can be a little chilly at night, so moss lines the nests of the patients area, and the Medicine Cat's nest. The herbs are stored torwards the front on a flat boulder with crevices in it.

This is where the Warriors retire to rest. Each warrior has his or her own nest, lined with comfy moss, that is replaced and replenished bi-daily. Warriors can be found in here night to day, depending on their patrol times

The Apprentices of ThunderClan are normally scurrying about camp, working on repairs, feeding the Clan, out training, and cleaning other dens, but they retire here to rest at night.

The retired warriors of ThunderClan reside here for the remainder of their lives. This place is quiet, and peaceful; located next to the Medicine Cat's Shelter.
It has strong pines that surround it, with many thickets and bushes. in fact, the only way to get in is through a small entrance.
This is a very spacious place, with a sandy area, and grassy nests.
