How to Build a Catio: A Safe and Enriching Outdoor Space for Your Cat
A catio—short for cat patio—is a secure, enclosed outdoor space that allows your cat to enjoy fresh air, sunshine, and the sights and sounds of nature while staying protected from potential dangers like traffic, predators, and disease.
Building a catio can improve your cat’s physical and mental well-being while also keeping local wildlife safe from hunting. Whether you live in an apartment, townhouse, or house with a backyard, there are plenty of ways to design a catio that suits your space and budget.
In this guide, we’ll walk you through the benefits of catios, different design options, and step-by-step instructions to build one for your feline friend.
Why Build a Catio?
1. Safety First
Outdoor dangers such as traffic, wild animals, poisonous plants, and contagious diseases pose serious risks to free-roaming cats. A catio provides a safe alternative where your cat can experience the outdoors without exposure to these hazards.
2. Protects Local Wildlife
Cats are natural hunters, and even well-fed domestic cats can kill birds, small mammals, and reptiles. A catio helps protect local wildlife by keeping your cat confined to a designated space.
3. Reduces Boredom and Behavioural Issues
Indoor cats can become bored, leading to destructive behaviours like scratching furniture, excessive meowing, or even stress-related health issues. A catio adds enrichment to their environment, keeping them entertained with fresh air, natural light, and the ability to observe wildlife.
4. Provides Mental and Physical Stimulation
A catio encourages exercise by giving cats space to climb, jump, and explore, reducing the risk of obesity. It also provides sensory stimulation, which can help alleviate anxiety and depression in cats.
5. Increases Longevity
Cats that live exclusively indoors or have access to a secure outdoor space like a catio tend to live longer than free-roaming cats. By reducing risks of accidents, disease, and predators, a catio can help ensure your cat enjoys a longer, healthier life.
Types of Catios
Before building your catio, consider the different styles available to determine which one best suits your home and space.
1. Window Box Catio
• Small, enclosed structure that extends from a window.
• Ideal for apartments or small spaces.
• Provides a sunbathing spot with fresh air.
2. Balcony Catio
• Encloses an existing balcony with secure netting or wire mesh.
• Great for apartment dwellers with a balcony.
• Provides a safe way for cats to enjoy a higher vantage point.
3. Porch or Patio Catio
• Converts an existing porch or patio into a secure enclosure.
• More spacious than a window box catio.
• Can be integrated into a backyard design.
4. Free-Standing Catio
• A larger, detached enclosure that sits in the yard.
• Often features multiple levels, ramps, and hiding spots.
• Can be customized with tunnels or connected to the house.
5. Tunnel System Cat
• Uses tunnels to connect different parts of the home or yard.
• Ideal for multi-cat households.
• Offers freedom of movement while remaining secure.
Materials Needed for Building a Catio
Before starting your DIY catio, gather the following materials:
✔ Wood (for the frame) – Cedar is ideal due to its durability and weather resistance.
✔ Wire Mesh or Hardware Cloth – Use sturdy, escape-proof mesh with small holes (½ inch or smaller).
✔ Outdoor Screws & Nails – To secure the frame and mesh.
✔ Hinges & Latches – For doors to allow access for cleaning and maintenance.
✔ Roofing Material – Plexiglass, polycarbonate panels, or waterproof fabric to provide shelter.
✔ Cat-Safe Enrichment – Platforms, shelves, climbing structures, scratching posts, and hiding spots.
✔ Outdoor Flooring – Pavers, grass, turf, or wooden decking.
Step-by-Step Guide to Building a Catio
Step 1: Choose a Location
• Determine where your catio will go. Ideal spots include near a window, sliding door, or backyard patio.
• Consider factors like sunlight exposure, wind direction, and accessibility.
Step 2: Measure and Plan
• Sketch out your design and take accurate measurements.
• Decide on entry points (e.g., a cat door from a window or patio).
• Plan for multiple levels and climbing areas to keep your cat engaged.
Step 3: Build the Frame
• Cut wooden beams to size and assemble the frame using screws and brackets.
• Ensure stability—the structure should be sturdy enough to withstand wind and weather.
Step 4: Install the Wire Mesh
• Secure hardware cloth or wire mesh to the frame using staples or screws.
• Check for any sharp edges that could harm your cat.
Step 5: Add a Roof
• Install waterproof roofing to provide shade and protection from rain.
• If using a wire mesh roof, ensure your cat has a covered area for shelter.
Step 6: Create an Entryway
• Cut out a section for the cat door or tunnel connection.
• Attach hinges and latches to the access door for easy maintenance.
Step 7: Install Flooring
• Choose flooring that’s safe and comfortable for your cat’s paws.
• Popular options include artificial turf, outdoor carpet, or wooden decking.
Step 8: Add Enrichment Features
• Install shelves, ramps, climbing poles, and perches for exploration.
• Place hiding spots and shaded areas to give your cat a retreat.
• Add a scratching post to encourage natural behaviour.
Step 9: Safety Check
• Inspect all edges, screws, and mesh for potential hazards.
• Ensure doors and latches are secure and escape-proof.
Step 10: Introduce Your Cat to the Catio
• Let your cat explore the catio at their own pace.
• Place familiar items like blankets or toys inside to make them feel comfortable.
• Supervise the first few visits to ensure they adjust well.
