Just putting up some very secure shelving would work. You can get shelving and supports at hardware stores. Just make sure it is properly secured to supports and the wall. As you know, I got a bunch of plastic bins and I can move them around to keep the cats interested. If I put blankets inside to weight them down them I can stack a few too. The cats do enjoy getting on them. The other place you already have is the cage top. I got rubber door mats at the dollar store. 3 bucks each and lined the tops of the cages with them to make it a safe surface for cat walking. A little rubber backed rug on top and they love getting up there. Those rubber backed mats are something I use a lot to protect anything the cats are allowed to climb on.
