How to Make a Catio in Construction: A Complete Guide

Cats love the outdoors, but letting them roam freely can expose them to traffic, predators, diseases, and other dangers. A catio (cat patio) is the perfect solution—it allows your feline friends to safely enjoy the fresh air, sunshine, and outdoor stimulation while staying protected.

In this detailed guide, we’ll explore how to make a catio in construction, covering planning, materials, design ideas, step-by-step building instructions, and tips to create a safe and enjoyable space for your cats.

What is a Catio?

A catio is an outdoor enclosure designed specifically for cats. It’s typically attached to a house, porch, balcony, or backyard, allowing cats to enjoy the outdoors without the risks of free roaming.

Catios can range from small window boxes to large free-standing structures that resemble mini greenhouses. They can be DIY-built using basic construction techniques or purchased as prefabricated kits.

Benefits of Building a Catio

Before jumping into the construction process, let’s look at the key benefits of building a catio:

• Safety for Cats – Keeps them protected from cars, predators, and diseases.
• Reduced Stress – Outdoor stimulation helps reduce boredom and behavior problems like scratching furniture or excessive meowing.
• Health Boost – Exposure to sunlight provides natural Vitamin D and encourages exercise.
• Wildlife Protection – Prevents cats from hunting birds and small animals.
• Peace of Mind – Owners can relax knowing their cats are safe outdoors.

1. Choose the Location

The first step is deciding where to build your catio. Popular options include:

• Balcony catio – Encloses a balcony space for safe outdoor access.
• Porch or patio catio – Uses an existing outdoor area.
• Freestanding catio – Built in the backyard, connected to the house with a tunnel.

2. Decide on Size

The size depends on your available space and how many cats you have. General recommendations:

• Small catio: 2×3 ft, good for window boxes.
• Medium catio: 4×6 ft, for porches or patios.
• Large catio: 6×8 ft or bigger, for multiple cats and climbing structures.

3. Budget Considerations

Catio construction costs vary depending on size and materials:

Materials Needed for Building a Catio

You’ll need basic construction materials and tools:

• Framing: Pressure-treated wood or metal pipes.
• Enclosure: Galvanized wire mesh, hardware cloth, or pet-safe fencing.
• Roofing: Polycarbonate panels, weatherproof canvas, or wood.
• Flooring: Grass, pavers, wood decking, or outdoor carpet.
• Fasteners: Screws, nails, brackets, hinges, and locks.
• Extras: Cat shelves, ramps, hammocks, tunnels, or climbing poles.

Step-by-Step: How to Make a Catio

Step 1: Design Your Catio

Sketch a simple design or use free online catio plans. Ensure you include:

• Entry point (window, door, or tunnel).
• Climbing spaces and perches.
• Shade and protection from rain.
• Secure door for cleaning access.

Step 2: Build the Frame

• Use 2×2 or 2×4 pressure-treated wood to build a sturdy frame.
• Create rectangular panels for walls, roof, and floor.
• Secure corners with metal brackets for durability.

Step 3: Attach the Wire Mesh

• Cover each panel with galvanized wire mesh.
• Use a staple gun or screws with washers to attach securely.
• Ensure there are no sharp edges that could harm cats.

Step 4: Assemble the Structure

• Connect wall panels to create the catio shape.
• Attach the roof panel (solid or mesh with a weatherproof covering).
• Install a door with hinges and a locking mechanism for access.

Step 5: Add Flooring

Depending on location, choose flooring that is safe and easy to clean:

• For grass/dirt areas, place pavers to prevent digging.
• For patios, use outdoor carpet or decking boards.

Step 6: Add Cat-Friendly Features

• Install climbing shelves and ramps.
• Add hammocks, scratching posts, and hiding boxes.
• Place a water bowl and shaded rest area.

Design Ideas for Catios

Here are some creative designs you can consider:
