Cat Fencing Topper for Chain Link, Wood, Vinyl

The Conversion System for Shorter Fences will allow you to add up to 3' overall to the height of your existing fence... Now you can use Purrfect Fence to Cat-Proof your fence or wall even if it is only 3' high!

❗ Have a fence or wall over 5 feet in height? Use the Standard Existing Fence Conversion System to cat-proof fences and walls 5' or higher!

The Conversion System for Shorter Fences will convert your shorter fence into a escape-proof fence for cats. The kits includes Cat-Proofer spring-loaded arms, extender for each arm, the associated mounting brackets and a 6' tall roll of fence based on the size of kit you choose.

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!

The extension tubes are made of thick 14 gauge steel (an arm set as high as possible on an extension tube can hold well over 50lbs). The scrunched end of the extension tube slides inside of the leg of the Conversion System Arms. The included high-strength epoxy bonds the pieces together. Once glued up, the extended arms slide into two mounting plates spaced a minimum of 4" apart secured to your fence posts with the top mounting plate set as high as possible on your post. Slide the arm to be at the desired height, tighten a set screw on each plate and your arm is secured to your post. Repeat this for all your posts and the fence material is ready to install.

Please note: If the fence is chain link, decorative aluminum or other metal picket fence you will need U-Bolts to secure the mounting bracket to the posts. You can use only one U-Bolt per bracket with this system so purchase one set of U-Bolts per post.

- 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 your chosen kit will cover your fence layout.

- Keep in mind that our Existing Fence Conversion System for Shorter Fences will provide up to 36" inches of additional height from wherever the upper mounting bracket is secured. So, if the bracket is mounted at the top of a 4FT 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 between 12" and 36" above where the uppermost mounting bracket is secured.

- 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 any 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 any questions please contact us.

Happy Cats!

One of our male cats was introduced to the outdoors on a leash for several months before we installed the Purrfect fence so we knew he liked being outside. We didn't really know the interest level of the other 3 cats. Since opening the Purrfect fence space in our backyard a few months ago, all 4 cats spend time out there each day. The 2 male cats will spend all day out there if allowed, and the 2 females especially like to enjoy the evening hours out there.
My experience on the human side of the Purffect Fence is that the product is high quality and the customer service was excellent. I shopped other systems that were less expensive, but I doubt I would have gotten the personal support during the purchase and install process that I got from Matt at Purffect Fence.
For those of you who want to enhance your pets' lives and enjoy an excellent customer experience, I recommend that you seriously consider (and ultimately buy!) the Purrfect Fence.

Works for cats and dogs

We had an existing chain link fence and we bought the fence extension. It was fairly easy to install. It takes time and it a two person job, but extremely happy with how it works. It keeps the cats in our yard and other animals out! My animals love being able to come in and out as they please and I know they are safe in the yard.

Perfect solution

When we adopted cats that were used to being outside, we felt it was unfair to only keep them inside but we wanted them safe. The Purrfect Fence was our solution. We attached the Purrfect Fence to the top of the existing fence enclosing our side yard, including a section for the gate. We used the extra netting to fill the vertical gaps between the fence and house. Originally we let the cats in and out through the sliding door from our bedroom, but recently we installed a cat door in the office window (so they don't wake us up every hour to go in and out at night) We also have been feeding a feral cat, Cleo, for many years and her favorite place to hang out has always been that patio. We were so surprised to see her there visiting Bob and Phil after we installed the Purrfect Fence. She figured out a way to slip down the fence head first through a small gap around a post. There was no way a cat could get out that way so we left it. She comes in for dinner at night and we let her out through the gate after feeding her breakfast in the morning. Sometimes she also spends time during the day in the catio. Occasionally we have coyotes in our neighborhood but I know my cats are safe and happy on their catio

Cats seem to feel safer

After a few missteps it is working purrfectly. It was more work to install than we expected, but the instructions were clear and understandable. We are very happy with it and think the cats are too.

Cats love being outdoors!

This is the best present I could have given my kitties. They love being able to explore their back yard and watch birds and squirrels. My Buttons will run full sprint, leaping with glee when let outside. I hear the song Born Free in my head every time I watch him. Neither of my cats have offered to try to escape their space. Although I had to install guards on a few trees located near the fence line so they couldn’t climb up the tree to leap over the fence. But overall it’s a winner with my Buttons and Buttercup and warms my heart to provide this freedom to explore for them. We love it. Best investment I could have made.

Cats happy, humans relieved

Having tried, and failed, to design and build diy fencing for our cats, we can say that cats are extremely good at escaping. Part of our specific problem is that we have a very difficult yard to fence in, with 3 terraced levels and mismatched fencing materials/heights, but proximity to predators and traffic made it mandatory (since we refuse to restrict our beloved cats to indoors-only). Frankly, had this not been possible, we would have sold our house and bought one in a quieter traffic area, so the purrfect fence actually saved us a great deal of time and money. Their staff designers gave us the plan, full install (by my wife and I) took about 3 days, which includes all of the fence patching and screening to plug holes, and now we have a 5,000 sq.ft. outdoors play area with trees to climb and mice to chase. When our new kitten gets bigger we plan to leave the cat door open at all times, so the yard becomes part of their living area - something we can do because in addition to keeping our cats in, these toppers/netting also keep predators (coyotes, mountain lions, foxes) out. This is absolutely the best option on the market for protection versus freedom for our loved ones. And as far as I can tell, Purrfect Fence is the only company doing it. We are glad we found them before we listed our house for sale!

Secure environment, great service

The cats are no longer jumping over the fence or going under the fence. I feel comfortable letting my cats out knowing they are in a secure environment. Customer service was top notch.
