This outdoor cat run is perfect! I use it for the feral cats that I take care of for feeding time and relaxation. I keep the door open but it allows for a little place of their own. Only problem I had was that one of the side panel was cut too short for the screw to fully engage on one end...but I looked over it and kept building. the cage is great just wish the top had a complete cover for rain. Easy to build and sturdy. One of the ferals enjoys sitting on the roof when there is nice weather.
