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.

- 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.

Improves cats' quality of life

We love our Purrfect fencing! Being able to - safely - go outside has greatly improved the quality of life for our two cats.

Effective at keeping my cats contained and my mind at ease!

I installed the netting and supports myself (I'm a grandma in her 60s). One of my cats escaped twice before I found all the small openings that needed to be rectified. The instructions caution you to think like a cat & figure out where they would try squiggle out. After just a couple of weeks, it seemed like the cats just accepted that this was their enclosed space and they quit trying to find places to squeeze through. This product allows my cats to enjoy the outdoors in a safe manner.

Safe freedom!

I love having this fence around my back yard! I can safely let my kids roam the "wilds" of the back yard with less worry about one of them escaping. As you can see from the photo, they try to escape but don't quite make it.

Life changing for four cats and owners!

I have had cat's all my life. Persian's that have been indoors and DSHC that have been allowed outside. I have a 180cm tall wooden fence around my garden but it has never held the cats on our side🫤 Last year I bought a Bengal and started to look for a solution to keep him along with the others inside our garden. That's when I came across Purrfect fence and my life changed! I got the best customer care I have ever had, great notes and recommendations on all the photos and measurements I sent and even a comment on how to make the system more "Bengal safe"
I simply love the fact that all my cats can now play safely in my garden thanks to furrfect fence!

Keeping Nusha safe

coming from Slovenia where it's very difficult to buy a product like this, I've had great experience buying it with friendly help from staff.
My cat Nusha loves the freedom that the new house feature provides. She tested it the first day and learned the lession well.
Even thouh it's a small garden she finds lots of things to do. She's keeping neighbors cats away. The fence is doing it's job as well of course. But I think this fella on the picture is just trying to seduce her. I call him Romeo.
Every day I hide her favorite toy somewhere in the garden and every morning she finds it and brings it back near the entrance. Then I pretend to eat it so she doesn't have the feeling of working for nothing. The teeth marks on the toy are mine (joke!!).
Thank you Purrfect fence team for making Nusha's life better and my indoor space cleaner.
Warm regards,
Darjan
