I take my on "walks" - for now I live in an apartment complex where they treat the grass, so he hangs out around my neck while we walk. I also give him new things, different rocks and logs, different textured bedding, and rearrange his stuff on a regular basis. In the fall I have also collected clean fresh dried leaves and put them in his cage after a decontamination period in the deep freezer.

I'm finally getting a house in November, so next summer he will be able to go out on the patio and in the grass for enrichment.
