Cat Fence Topper for Existing Fences


The Existing Fence Conversion System's revolutionary Cat-Proofer™ extensions make it easy and affordable to convert most any 5' or 6' (or taller) fence or wall into a cat-proof barrier.

The pivoting fence extensions are attached near the top of the inside of your fence and the high strength mesh material is stretched between them attaching with the included zip ties. Simply secure the lower portion of the mesh material to your fence or wall and your cat-proof barrier is complete.

The system will adjust to fit just about every gate and corner situation making it very versatile. Included with each 100' kit are (12) Spring-loaded arms (12) Arm Mounting Plates w/ arm setscrew, 100' of 4' high heavy duty black poly fence (1.75" x 1.75" grid) and (100) zip ties (for 50 ft order increments it will include half of the listed components.) Keep in mind that every fence is different and there are no universally followed guidelines for post spacing, height, materials used,etc. A 50ft kit is designed for the average 50 linear feet of fence. 100 ft kit is designed for an average 100 linear feet of fence. A 200 ft kit is designed for the average 200 linear feet of fence. If you have gates, turns, short or long spans between posts then you may find that you need more or less components than comes with the kit. If in doubt, contact us first!

❗ Have a fence or wall under 5 feet? Use the Conversion System for Shorter Fences to cat-proof fences and walls as short as 3' high!

The system is built to last. All arms are galvanized steel with a black powder coat finish, the arm hardware and springs are stainless steel and the fence material is UV stabilized with carbon black and additional chemical UV inhibitors.

IMPORTANT: The fence mesh is the same 1.75" x 1.75" very strong poly material we use in our Free Standing System. - NOT a flimsy netting.

Accessories are available for, decorative aluminum, wrought iron, and PVC fences as well as walls. 2-Pack of Arms are also available. Please call us 888-280-4066 for custom orders or special needs.

- Fasteners for holding hardware to building/home are not included. Fasteners should be chosen based on the type of material covering the building/wall/fence (wood screw, masonry screw, etc.)

-As the table above shows, a 50-foot kit comes with 50 feet of fencing material, not 60 feet.  A 150-foot kit comes with 150 feet of fencing material. It is advised that you consider ordering approximately 10% or more than you need to allow for cut pieces and minor errors in installation.

-The above table applies to orders placed after 12/26/19.



Installation

Items of note when planning your order/layout:

-Each existing fence is unique! The maximum span between arms is 12-14 feet. 8-10 Feet is preferred. Count and measure the distance between your posts to ensure that a kit will cover your fence.

- Keep in mind that our Existing Fence Conversion System will provide up to 12" inches of additional height from wherever the mounting bracket is secured. So, if the bracket is mounted at the top of a 6FT fence, then the finished Purrfect Fence height can be as tall as 7FT. This is adjustable and can be set at any height you prefer based on changing the height of the mounting bracket.

- Our patented system works by forcing your cat(s) to climb up the fence which activates the spring-loaded arm from the bottom if they are able to reach the top (most are not.) So, for maximum effectiveness, it is important that the finished height of your Purrfect Fence be tall enough so your cat cannot simply leap over it. For most domestic cats the minimum finished height (measured from the ground to the tip of the Purrfect Fence extension) we recommend is 6FT, though we prefer it to be taller when possible. Even so, we have had customers tell us it was effective for their cat(s) at shorter heights. However, higher is always better and may be necessary if your particular cat or cat breed is capable of leaping higher than the average healthy and athletic (domestic shorthair) cat. 

Fasteners for holding hardware to building/home are not included. Fasteners should be chosen based on the type of material covering the building/wall/fence (wood screw, masonry screw, etc.)

-Gates in your fence line require special consideration. Read below for more information on gate planning and installation.

Gates

Gates need to be considered separately for your layout plan. Each gate in your existing fence is likely to need additional components depending on the location and operation.

Inward Swinging Gate

Many inward swinging gates require 1-2 extra arm/bracket(s) per gate. Your situation may vary. If you have questions please contact us.

Outward Swinging Gate

Many outward swinging gates require 2-3 extra arm/bracket(s) per gate. Your situation may vary. If you have questions please contact us.

We love installing Purrfect Fence

The Purrfect Fence is a suitable and effect way of restricting your furry pets from jumping over the wall. It is easy to assemble & install. If I may add, I loved the quick response from your team. Right from solving the issue to preparing a schematic drawing for installation.

It really works

So far the fence has worked as it was designed to. We had a neighborhood cat get into the yard and as desperate as he was get out he couldn't. He was only able to get out by going under the gate. My cat doesn't even try to get out anymore.

Really Purrfect cats love outside

So far so good we even went to grocery store yesterday evening and returned to purrfect kitties lounging in the back yard safely. We did have our jumper make an escape attemp but she failed and was returned to earth safely. Install on masonry wall was pretty straight forward.

Works great!

I put this up in a residential neighborhood to keep my cats in. It works great. No cats have escaped and I did have someone else's cat get in and panicked couldn't get out. Easy to install and again it works great.

Relieved my cats are safe

Easy installation and quality components. Expensive for what is included. I didn’t mind paying the high price for the convenience.

The perfect solution for our escape artist!

We have tried many different systems over the past 3 years, but one of our cats - a very determined Houdini - always found a way to get out of our garden, even when we had coyote rollers. Since we installed the Purrfect fence about 2 months ago she hasn't been able to get out. The system looks great too. Our only regret is we didn't find out about it sooner. It's such a relief that we can keep her safe now, while she can still enjoy all the thrills of being outside!
