Thanks, I really like these suggestions! I'll have to plan more fun things for him!Now you can really get fancy with the enclosure. Try some logs or large rocks to make a site barriers. If he can't see from one end of the enclosure to the other it will feel much bigger to him. You can add dirt here and there to make some hills and varied terrain. My tortoise likes to dig under a large piece of bark. Russians seem to like to hike up and around and over things. It's good for them and keeps them a little entertained. I really like designing and fixing up the enclosures.
