I, too, agree with Margaret -- our cat is an indoor cat. In our neighbourhood, there is simply too much traffic and too many racoons for him to be safe outside. However, we would very much like to give him some (limited) 'safe' time outdoors, and taking him out on a harness is tedious (for both of us). Does anyone have any experience with building enclosed cat runs, or know of where instructions / ideas can be found on the net?

Thanks!
