If you’ve ever watched your indoor cat gaze longingly outside, you’ve probably wished they could enjoy the outdoors—without the dangers. That’s where a catio (cat patio) comes in.

Building one might seem intimidating, especially if you’re not a seasoned DIYer—but don’t worry. Whether you’re working with a backyard, balcony, or sunny window, this guide covers everything from planning and materials to building your first frame.

Let’s get started on a catio your cat will love—and you’ll feel proud to create.

Why Build A Catio?

First off, what is a catio? A catio—short for cat patio—is a safe, enclosed outdoor space designed just for cats. It lets them enjoy fresh air, sunshine, and nature without the dangers associated with free roaming. Whether it’s a small window box or a full backyard retreat, a catio blends freedom and safety, enriching your cat’s life and giving you peace of mind.

More than just a play space, catios offer the sights, sounds, and scents of the outdoors—like rustling leaves and birdsong—that keep your cat mentally and physically stimulated.

Catio Health Benefits

  • Encourages exercise: Climbing, jumping, and exploring promote a more active lifestyle.
  • Improves mobility and joint health: Regular motion helps keep muscles and joints flexible.
  • Alleviates boredom: A constantly changing outdoor view keeps your cat mentally stimulated.
  • Supports natural instincts: Watching birds, smelling plants, and feeling the breeze satisfies their hunting and sensory needs.

Step 1: Plan Your Perfect Catio

Assess Your Space

Start by thinking about your cat’s personality. Do they love watching people or cars, or are they sensitive to noise? Choose a spot where your cat will feel safe and relaxed—it’s their retreat, after all. Aim for a balance of sun and shade, and consider access: will it connect through a door, window, or tunnel? These details will help shape a catio your cat will truly enjoy.

Consider Your Cat’s Needs and Personality

Each cat is unique, so tailor the catio to their needs. Energetic cats may enjoy climbing features, while older or shy cats might prefer low, cozy, or enclosed spots. Keep their age, confidence, and activity level in mind to create a space that feels just right.

Step 2: Choose Your Catio Style

Types of Catios

When it comes to catio design, there’s no one-size-fits-all. Choosing the right style depends on your available space, your cat’s personality, and how you want them to access the outdoors. Here are three popular types to consider:

  • Window Box Catio: A compact option that attaches just outside a window, perfect for apartments or small spaces.
  • Balcony Catio: Great for upper-level homes, this type provides fresh air and views while keeping cats safe above ground.
  • Freestanding Structure: The most spacious and customizable style, often built in backyards with multiple levels, shelves, and lounging zones.

Step 3: Gather Materials and Tools

Recommended Materials

When it comes to building a catio, choosing the right materials is essential—using cheap or flimsy components can put your cat’s safety at risk. We recommend using weather, rot, and insect-resistant lumber, such as pressure-treated wood or naturally durable options like cedar or redwood.

For roofing, check out this in-depth guide on the best catio roofing options. We suggest using a strong, long-lasting material like polycarbonate panels or corrugated metal roofing to provide protection from the elements year-round.

When selecting your screening or fencing, keep in mind that it needs to withstand even the most determined escape artists and curious predators. Our top choice is 1×1 black PVC-coated critter fencing—not only is it visually clean and unobtrusive, but it’s also tough enough to keep out predators like coyotes, owls, hawks, and more.

Additionally, be sure to use galvanized steel screws, rust-resistant fasteners, and heavy-duty hinges and latches. These elements will help your catio stand the test of time by resisting corrosion and maintaining structural integrity through all kinds of weather. Every detail matters when building a space that’s secure, durable, and built to last.

Step 4: Build Your Catio

Before picking up a hammer, start with a plan. A basic sketch can guide your build and help prevent costly mistakes. If designing from scratch feels overwhelming, you’re not alone. Companies like Cat Topia specialize in catio design and construction, helping bring your imagination and vision to life. DIYers can also find free templates and inspiration through online communities with a little digging. Having a clear design upfront makes the entire building process smoother and more enjoyable.

With your plan and materials ready, begin by constructing a level, sturdy frame—the foundation of a safe and lasting catio. Securely attach wire mesh or fencing, checking for gaps or sharp edges, and reinforce vulnerable spots, especially in wildlife-prone areas. Finish by adding a weather-resistant roof, durable flooring like pavers or decking, and entry points such as a pet door or tunnel connecting to your home. Don’t forget a secure door for human access. Prioritize safety, comfort, and ease of maintenance at every step.

Conclusion

Building your own catio is more than just a weekend project—it’s a meaningful investment in your cat’s health, happiness, and safety. Whether you’re crafting a small window box or a spacious backyard retreat, every step you take brings your cat closer to a life full of fresh air, stimulation, and adventure—all within the safety of your home’s boundaries.

Don’t be afraid to get creative, take your time, and most importantly, enjoy the process. Your cat will thank you with every sun-drenched nap and bird-watching session. And when you’re done, we’d love to see what you create—share your build, spread the word about humane outdoor alternatives, and be sure to check with the Humane Society of Utah for more resources and inspiration.
