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.

* 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.

Purrfect Fence Conversion Explained

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.

Frequently Asked Questions

Will this actually contain my cat?

Yes! When properly installed, Purrfect Fence has an industry-best 99.9% effectiveness rate, and has helped over 100,000 cats safely enjoy the outdoors.

How much fence do I need?

We can help you outfit any size yard. Our planning engineers can recommend the best setup based on your yard's size, your cat's needs, and your budget. Use our free Fence Planner Tool to trace your yard, browse our sample layouts, or fill out a design form for a custom plan and estimate. As a guide, a 100-foot kit makes roughly a 24' x 24' enclosure (576 sq ft), and most customers use the back of their house as one side to enclose even more space.

Do I need any extra posts or parts?

Each kit includes everything sized to your selected length. If your layout has multiple turns or specific side lengths, you may need extra posts. Every end, corner/turn, and change in grade needs a post, and posts should be no more than 14' apart. You can always add more components or posts as needed. We advise ordering about 10% more fencing material than you think you need, to allow for cut pieces and minor installation errors.

Is there a discount if I add a gate?

Yes. Add any gate to your order and get $69 off your Freestanding System automatically at checkout. Many enclosures need at least one gate for access, and many customers often add a second wider gate for their mowers or if other equipment needs its own entrance.

How long does shipping take?

All kits ship free within the continental US. Most orders ship within 1-3 business days and arrive within 5-7 business days depending on your location.

How hard is installation?

Our systems are designed for DIY installation with basic tools you probably already own. Most homeowners complete their install in a weekend. If you'd prefer professional help, we have a nationwide network of installer partners. The free-standing system requires a power drill, wire snips, and a sledgehammer. Each kit comes with detailed written instructions and helpful videos, and our expert staff are available to guide you if anything is confusing or unexpected!

What is the Escape-Free Guarantee?

If your cat escapes through a properly installed Purrfect Fence system, we'll work with you to solve the issue at no additional cost. We've maintained a 99.9%+ success rate across nearly 100,000 cats.

How long will my fence last outdoors?

Purrfect Fence systems are built to last. Many customers report 15+ years of use. All parts and materials come with a 3-year warranty, and every component is individually replaceable if needed.

The posts, arms, and metal components are galvanized or stainless steel, with black components powder-coated for added outdoor durability. The welded-wire chew/dig guard and the polypropylene mesh are both UV-stabilized to resist damage from sunlight. The mesh has a breaking strength of around 600 lbs.

We've even tested our materials against competitors by submerging them in saltwater brine for weeks, and we stand behind Purrfect Fence as the strongest, most durable cat containment fence available.

Why is Purrfect Fence the most secure cat fence available?

The secret is our patented Cat-Proofer™ extender arms: if a cat climbs to the top, the arms pivot downward under their weight, and the sensation causes cats to naturally let go and drop safely back to the ground. Our patented design has seen 19 improvements over the past 20 years.

Why Purrfect Fence Is the Most Secure Cat Fence Available

The secret is in the patented Cat-Proofer™ extender arms, which enable the entire upper section of the fence to pivot. If a cat climbs to the top of the fence, the extender arms pivot downward under their weight. The sensation causes cats to naturally let go of the fence, dropping safely back to the ground.

A Tough Cat Fence Built to Last

All of the materials and components used with our Freestanding Fence system were selected for a specific purpose: to work together and create a long-lasting fence barrier.

The posts, arms, and metal components are made with galvanized or stainless steel. Black metal components are powder-coated for durability outdoors. The bottom portion uses galvanized welded wire as a chew guard and dig guard, keeping cats from digging or chewing their way out and keeping unwanted critters from getting in.

The upper portion is durable polypropylene mesh — heavy-duty but flexible, with a breaking strength around 600 lbs and proven difficult for cats to climb. Like the welded wire coating, our poly mesh is UV-stabilized for longevity outdoors.

A Modular and Flexible Cat Containment System

Purrfect Fence is designed to easily secure a perimeter of cat-proof fencing. It can be configured to different sizes to make your system as spacious as you'd like. You can also use freestanding cat fence segments together with cat-proofed areas of an existing fence.
