This is a little house cat scratcher thingy that I assembled for Joely a while back and he doesn't really use the house part as far as I can tell but he does use the scratching part.. I've noticed him playing it behind me while I play arcades.. it's his arcade basically..
These are built sort of like my arcades where. You basically start with one side panel.. add the middle pieces and seal it up with the other panel.. haha
