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 100 ft kit is designed for an average 100 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.

Accessories are available for, decorative aluminum, wrought iron, and PVC fences as well as walls. 2-Pack of Arms are also available. Please call us 888-280-4066 for custom orders or special needs.
