Our fence conversion system for cats attaches to any type of fence, including wood, metal, brick, chain link, and vinyl.

Your cat will remain in your yard safely enjoying the sunlight and fresh air.

 

Cat Fence Topper for Existing Fences

The system stops cats from jumping over a fence and is compatible to nearly any existing fence. Each 100’ kit of fence conversion system for cats comes with 12 spring-loaded arms, 12 arm mounting plates with screws, 100 feet of 4-ft heavy-duty black poly fence (1.75" x 1.75" grid), and 100 industrial grade zip ties.

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, attached with the included zip ties. Simply secure the lower portion of the mesh material to your fence or wall and your fence conversion system for cats is complete. If you’re looking for ways to stop a cat from jumping over a fence, Purrfect Fence’s Existing Fence Conversion System for Cats works for most 5-6 ft. or taller fences or barriers. If you have a shorter fence, consider our fence conversion system for cats for shorter fences.

Every fence is different, and there are no universally followed guidelines for post spacing, height, or materials used. Because of this, we also offer kits designed for 50 and 200 linear feet of fence. If you aren’t sure what you need, contact us! The experts at Purrfect Fence are happy to help you over the phone, by email, or through live chat.

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 fence conversion systems for cats 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 email or call us at 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.

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.

No more cat fights

I'm really thankful to have a protected backyard now with Purrfect Fence. I have always had indoor-outdoor cats, but my "big guy" had developed a habit of getting in terrible fights with a neighbor cat. He came home several times with scratches all over, and I was worried that he or the other cat could get worse injuries if it kept going. That inspired me to enclose the backyard using Purrfect Fence. It has worked out so great and really gives me peace of mind, while the cats still get to enjoy their outdoor time. Now my big guy doesn't have to defend his own property. It took a few tries to seal up all of his potential exits, because he is a Houdini. But now we have gone several months without an escape, and everyone seems happy. I also feel more comfortable leaving the cat door open more of the time when I know they will only go so far, so they enjoy that freedom.

Greater security for keeping our cats in the yard

The website for Purrfect Fence shows many examples of how it can be used with various types of fences, or as a stand-alone fence. We used the arms and netting to attach to our existing wood fence. We ended up having to order a couple of additional arms as we have a couple of corners that required several arms close together. It's not the most attractive thing to have on your fence, but it does the job of discouraging cats from jumping, so we can relax in our back yard, knowing that we don't have to watch them every minute. There are some sections of the fence where I went up to 14 feet without an arm, and I was able to do so without the fence sagging much. It takes a bit of skill to get it right, as the first few sections I I put up do not look as good. I highly recomment watching the installation video on their website, as it covers everything you need to know, particularly how to deal with corners. The cost is a bit high, particularly when ordering separate arms (over $70 for two). The netting itself is ideal, and we could not find the exact same thing online or at local big box hardware stores. Most of the netting on the market is not as well suited for this purpose.

Wow!🤩

We purchased the fence in December and installed in Feb. the cats cannot escape. They tried and you know what? I have to hand it to them, they are still trying. I am relieved they cannot run in the street anymore and I am not stressed out about it. That is worth its weight in gold to me.

Their customer service was unbelievably wonderful. I kept saying to my husband, “I can’t believe how great they are.” When one of the boxes arrived with a hole and a part was missing, in less than 24 hours a replacement was shipped to me at no cost.

The installation was relatively easy, considering we installed in the first week of Feb. I cannot recommend the tools enough! The hog ringer—chef’s kiss!!

This fence is an investment in your cats. It keeps them from roaming and it keeps the neighbors happy too. So glad we purchased.

Happy for my cats!

Very well. Also happy that it is almost invisible so the HOA won’t complain. We were even able to enclose their favorite climbing tree!
