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.

Life Enhancer

This has made such a difference in the lives of our cats. We know both our cats have a safe haven in our back yard and get the stimulation they need to live happy, healthy lives. I have seen it keep our cats in and other cats and wildlife out. We have a 6ft privacy fence and the equipment was easy to install and took us just a few hours to complete, even with a large yard! We love it!!!

Perfect fit, cats are secure.

We added this to our enclosed Townhouse Deck/Fencing, it's perfect. Our cats are secure and I no longer worry about them trying to escape. They love the freedom of being outdoors and I love not worring about them and their safety.

Love, love, love it !

We recently sold our home in Miami where our cats roamed free. Since we are no longer comfortable letting them run loose on our rental property, the Purrfect Cat Fence was a perfect solution. We now have a cat yard and a dog yard and everyone is happy and safe !

Easy to assemble, great quality.

Stopped the panic attacks

Waited a long time for these two kittens because we were robbed of another feline family member to a coyote after he got out and jumped fence a few years ago. Fast forward to today, we had two dogs perfectly trained by a doggie door. During CoVid’s initial quarantine months, we started fostering kittens. We had planned on getting another cat eventually so we were getting our dogs used to cats again and kittens and cats used to dogs in families. After many foster cats, we ended up adopting a pair of calico sisters. All was well and good in house until kittens became bigger and became curious about the dog door. It was a months’ long battle. Spray bottles, noise makers, even splurged for the hated correction collars but we were panicked to lose another cat. We even toyed with removing the dog door (more disruption to household). The correction barrier collars eventually were a bust also as they just ran like bulls past the correction and through the dog door.

We searched long and hard for solutions. Many home made solutions available but too much work and price involved. Happened upon your product and read reviews and decided to purchase.
Needless to say it has been a life saver. The panic of a missing cat has left. The kitties get to play all day/night with all kinds of flying flora and fauna. They can play with their dog siblings. They also sprawl in the middle of yard napping.

Easy to put up. They helped on what size I needed after I asked questions on line. I did struggle a bit with the corners of yard but they also gave me a solution for that.
Best animal related purchase, Ive made.

In pictures, you can see the barely visible fence and some content animals.

Keeping Cats in the Yard

We have a 300 Foot Perimeter, concrete brick, and two side gates. We bought a hammer drill and some anchor screws and got to work. It's not an exact science, so you have to be a little handy. The hardest part is getting the corners, but we got the hang of it. I recommend pulling the fence tight to get a straight line, it may require some adjustment after putting it together.

Liberated! Me and my cats.

The system went up super easy. I was able to put it up in small yard in a couple hours. My cats used to try to escape over the fence every time they went out. Now they don’t even try. I feel comfortable enough to leave them outside without supervision. We are all loving the new found freedom.
