The Nursery is the strongest den of them all. It is in the shade of a willow tree, with twisting branches. The den is underground, beneath the tree. It is a large open area, with little sleeping hollows off the side. The tree is a good place for Kits to play, since it is only a fox-length away from their cozy nests. It is very warm underneath, but it never heats up in Green-Leaf, or freezes in Leaf-Bare.
