Good Gosh, K&L, I am moving to Arizona! That is such a cool cat COMPOUND! Did you two build it? And, is that 'typical chain link? And, did you use one inch poles? How did you figure out the side mount? Is it attached to the house? See, I have a covered porch, and, I would like to build something (smaller, of course) and let my cats access it with my bedroom window, which is under the porch (kinda sounds trashy, doesn't it?). I was wondering if I could get away with chicken coop...but, what if someone (Allie) tries to scale the wall?
