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 theConversion 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.

A relief! no more worrying

The Purrfect Fence extension onto our 6 foot chain link fence went up very smoothly; my husband and I did it by ourselves. Matt in customer service was very helpful in planning the project, as we had 3 gates to contend with and 350 feet of fence. We used U-Bolts and in some cases, screwed the brackets directly into the corner gate fence posts. Due to weather, we've just recently completed the extension and there's not been a lot of time for our cat Medley to try it out. But so far, I think just the fact that it's there is a deterrent. Before this, she was scaling the 6 foot fence in one leap -- with us watching! The Purrfect Fence is giving us peace of mind, knowing that if and when Medley tries to escape now, the articulated arms will fall down and dump her back into the yard. Before this, we considered using a regular generic extension, but realized that the special arms of the Purrfect Fence would be so much more effective against a Houdini cat like Medley. And with some cats, all it takes is one escape to get lost or eaten. Whatever it takes to keep Medley safe and inside the fence is worth it! (I'll be posting some photos on Instagram at StarkRavingCat when the weather improves.)

Works great! Easy installation.

I’m a 65 year old Grandma and was able to do most of the installation of a 200 ft barrier myself. My nephew helped put up the netting as that was a little awkward, but we had it finished in about 8 hours. My cat is now free to play outside and none of the neighbor cats have been able to get into our backyard. Great product!

So pleased my cats are safe!

I can't believe how well the Purrfect Fence works to keep my agile cats safely in my yard. After one of my cats was hit by a car in front of my house, I have been struggling with the decision to make my cats indoor or outdoor cats. With the new fence, they get both!

Had a young stag hound who could jump our fence. We used the cat fence because of the hinged supports. Worked like a charm. Figured she wouldn't be able to climb either due the hinge and she couldn't.

This has been a life changer. I’m so glad I finally got this existing fence conversion system. It also helps keeping neighborhood cats out which was causing my male cat to spray. It was easy to install and customer service was so helpful and supportive with all my questions. Thank you!

Purrfect fence is the BEST!

My cats are super happy and absolutely love it now that they go out in the backyard! When they were exclusively indoors, I used to play with them everyday to avoid behavioral issues but now, they chase insects, butterflies, and an occasional squirrel so I don’t have to play with them that much anymore. They also fight less with each other. I think they appreciate being able to go out because they’re definitely a lot cuddlier with me now. LOLOL

Purrfect fence gives me peace of mind that my cats are safe and can’t escape. At first, I was concerned about the price and how it would look. Turns out it looks good! Installation wasn’t a problem and the price was worth it! The Purrfect fence team was also very helpful and responded back quickly whenever I have questions (and I did have a lot) lololol.

All-in-all, my cats and I are very happy with the fence and I wish all cat parents would get it for their indoor cats! :D

PurrFect!! Kitties are so happy!

We’ve had our PurrFect fence up for over a month now and our two kitties are loving it. They are more active than ever and we have the confidence it will continue to keep them in the yard. The system is super flexible too. I was able to install just under 300 feet around obstacles such as small trees and trellises without issue. I couldn’t be happier and neither can Lulu and Poppy.
