i've been meaning to do this for years now. i wanted to build it inside the house but we don't really have the lay-out for it. so against the fence it goes. this stuff is time consuming. i spent today getting supplies and building the main runner. off of this i will add rooms and more runners connecting the rooms. the kitties like it so far. they were climbing the post to get on the roof. now they have a nice runner.
