You're lucky to have a pine tree in your yard! With the pine cones you would wash them and either just hang them in the cage, or you could stuff some treats into the little openings and make it a foraging toy.
And that's a BRILLIANT deal you got on the cage. You should post a photo in the cage thread in this forum.
