I had built and enclosure at our old house. It took 3 months to build all the frames, the gate, put a roof on it, and frankly I was ugly. Our escape artist found a way out in about 30 minutes. Purrfect Fence went up in one day and none of our cats have made it more than about 4 feet up the fence before jumping back down. They also have twice as much space as before and it feels like more because there is no screen above them. We even have trees for them to climb inside the enclosure that don't come near the fence where they might jump out. When we decided to change the design, we ordered a few more posts and it was done in a couple of hours. Customer service has also been great in advising us what problems to avoid. I could not have asked for a better solution!
