The purrfect fence is 99.99% effective due to 20 years of research into cat containment and the use Purrfect Fence’s patented spring-loaded arm. In those situations where escapes are reported we worked with the cat parent to address the root cause of the escape 100% of the time. Often times, this is due to a mistake during installation, environmental issues such as trees, window sills next to the fence, or other common yard features assisting in the escape such as furniture.
Even so, our incredible track record is due to several factors, but most importantly to the flexible/unstable nature of the polypropylene grid, the arched top, and the chew resistant bottom that gets overlapped 6" onto the ground. For the handful of expert climbers that might be able to make it near the top of the fence, they will then be denied escape due to the effectiveness of the pivoting extender arms that turn your cat(s) back toward the ground. Having said this, installation technique is still very important because any small opening can be a potential escape route for a cat. It is important that our written and video instructions are followed.
