🐾 DIY Guide: Hook & Wire Canopy over Window

A step-by-step guide to creating a mesh canopy above your window to prevent your cat from leaping off the sill and escaping into the garden.

How to Build a Mesh Canopy Over Your Window to Stop Your Cat Escaping the Garden

Cats are clever climbers and curious explorers, and sometimes, all it takes is a well-placed windowsill or flower pot for them to make a leap to escape and bypass the Cat Fence Barrier. The solution is to create a mesh canopy using a hook and wire framework. In this guide, we’ll show you how to build a simple canopy over your window to keep your cat safely within bounds.

🧰 What You’ll Need:

Wall hooks or eye bolts (stainless steel recommended)
Galvanized wire (strong enough to hold tension)
Cat mesh netting
Wire cutters
Drill with a masonry bit (for brick walls)
Measuring tape
UV-stable cable ties
Shears

🛠️ Step-by-Step Instructions

Step 1: Measure and Cut the Mesh

Begin by measuring the distance from the edge of your overhang barrier to the window edge.
Using this measurement, cut a section of mesh from your 1-metre-wide roll. This will form the main covering of your canopy. In some instances, you may need a 2-meter-wide roll

Step 2: Install the Wire Support

Drill holes into the brickwork or mortar directly above the window, aligning with where the wire will run.
Screw eye hooks into the holes to create anchor points.
Thread the galvanised wire through the eye hooks, and tighten it to create a firm, straight line. You can increase tension by twisting the eye hook.

Step 3: Secure the Mesh Canopy

Use UV-resistant cable ties to attach the mesh to the wire framework above the window.
Stretch the mesh down and fix it to the edge of your overhang barrier.
Finally, use shears to trim the mesh into a clean, triangular shape that sits neatly against the wall and canopy edges.

Frequently Asked Questions

We suggest keeping a minimum of 6ft/1.8m between the highest leap point and the cat barrier. Window sills can create leap points for cats when they are located next to the perimeter. We suggest building a window sill canopy and you can read further guidance on this here.

If you have a mature garden with lots of plants, the cats will absolutely love the enrichment it offers. In order to install the fence barrier, you may need to undertake some pruning and trimming. For example, you'll generally need the top 1ft/30cm of your fence or wall to be clear of plant growth. For more detailed guidance on preparing your garden, please see our blog.

Yes. Fence-top barriers can be fitted to existing fencing to prevent cats from climbing over garden boundaries. The angled overhang design makes it difficult for cats to gain the leverage needed to complete a climb.

ProtectaPet’s overhang features the patented BengalBend™, which is specifically engineered to deter even agile breeds, allowing cats to enjoy a safe outdoor territory.

The only sure-fire way to ensure your cat won't venture further than your garden is to use a cat containment system. Cat Fence Barriers are the easiest method to convert your entire garden into a cat safe territory, if you have suitable pre-existing fencing or walls.

Whether you have small garden or a large garden, there are lots of options for making your garden cat proof. Cat fence barriers are a neat and simple solution to giving your cat access to the whole garden. Or, if you have a small garden, you could consider an outdoor cat run or catio.
