Thanks! Yes that is Scout, my rescued baby I found on my doorstep at 11 weeks. The cardboard tube is called a Quik-Tube(the brand name)...you should be able to find it at any home improvement store. It's suppossed to be used as a concrete building form...but I think it's great for the kitties. In the store, it's usually around the concrete or building forms. Only cost about $7.
