How to Cat Proof a Balcony

Below you will find a step-by-step guide on how to cat proof a balcony.


Step 1) Plan & Measure Your Balcony


  • Measure your space and design your enclosure accordingly: determine the height and length of the railing.
  • Identify and measure any gaps or open spaces between railings or on open sides that need to be covered.


Step 2) Prepare the Netting


  • Use wire cutters to cut the chicken wire to the appropriate lengths, adding a few extra centimeters to each piece for securing the wire at the top and bottom.
  • Mesh or netting is one of the most efficient ways on how to keep cats off balcony railing.


Step 3) Mark Screw Locations


  • You’ll need to attach the netting to something at the top and on both sides of the terrace.
  • Mark the locations where you will install hooks or eye screws, spacing them every 15-30 cm.


Step 4) Install Eye Screws or Hooks


  • Drill pilot holes at the marked locations if needed. 
  • Securely screw in the hooks or eye screws into the solid base.


Step 5) Attach Wire to Hooks


  • Start with one section of your space and attach your prepared netting.
  • Loop the chicken wire through the hooks or eye screws and secure it with cable ties or wire, ensuring it is taut and securely fastened.
  • Note: For wooden bases, you can use staples.


Step 6) Secure the Bottom to the Railing


  • Continue by securing the bottom edge of the chicken wire to the base of the railing.
  • Use cable ties or wire to attach the wire to the railing at regular intervals, ensuring it is tight and secure.


Step 7) Secure to Base


  • If your balcony has a solid wooden base, you can use staples at 15cm intervals to attach the wire, ensuring the staples are securely fastened.
  • If your balcony has a cement/stone base, use same hooks as in step 4.

Step 8) Attach on the Sides


  • Pull the chicken wire up and secure it to the sides (to any vertical bars or posts) of the railing by using cable ties or wire. 
  • Ensure the wire is taut and that there are no gaps where your pet could squeeze through.


Step 9) Install the Remaining Areas


  • Following the process of how to cat proof a balcony described in steps 2-7, continue attaching the chicken wire to both sides of the terrace as well.


Step 10) Join Mesh Together


  • Join the mesh together at the corners using cable ties or wire ties. 
  • If your netting is not large enough, you can easily join two pieces of mesh together in the same way.


Step 11) Furnish & Supervise


  • Fill any gaps with smaller pieces of wire, securing as before in the process of how to cat proof a balcony.
  • Test the installation by pushing to ensure it’s secure before letting your feline out. 
  • Inspect the chicken wire edges for sharp points and loose spots.


Alternatives: Choosing the Right Material 

Cat netting

Lightweight, flexible, and easily customizable to fit different balcony sizes. However, it may not be the most durable choice and may not be suitable for kitties that are very determined to escape.

Plexiglass panels

Durable and weather-resistant, this option offers a clear view while effectively blocking kitties. However, it tends to be pricier and requires more effort to install than simpler netting alternatives.


Provides a secure outdoor space for cats, offering durability and customization. However, it requires more space and can be significantly more expensive and complex to install.



  • Also check if there are restrictions on what can be left out on your balcony and if temporary changes like adding netting are allowed.
  • Regularly maintain netting for security. Keep your space clean to prevent hazards, like sharp edges, loose nails or small objects that your kitty might swallow.
  • Opt for a PVC-coated mesh for weather resistance and choose a small hole size.
  • You can also paint the mesh to your liking.


Do’s & Don’ts

  • Replace poisonous plants like lilies and daffodils with pet-friendly options such as cat grass.
  • Remove bird feeders and wind chimes to prevent them from hunting.
  • Make the space entertaining with safe climbing and perching spots.
  • Furnish with a cat tree, shaded areas, and comfortable furniture.
  • Always supervise your kitty on the balcony to ensure safety.
