What Is A Catio? (& Why Build One?)

If you’ve ever wished your cat could safely enjoy the outdoors without the risks that come with it, a catio might just be your new favorite project. These secure outdoor enclosures are becoming more and more popular with cat parents, and for good reason! Let’s dive into what a catio is, why cats, and humans love them, and how you can get inspired to build one of your own.

First Thing’s First: What Is a Catio? … And What Is It For?

What is the purpose of a catio?

A catio is short for “cat patio”, and is an enclosed outdoor space designed specifically for your cat to enjoy fresh air, sunshine, and all the sights and sounds of nature, without the dangers that come from roaming freely outside. Think of it like a screened-in porch, jungle gym, and lounge zone all rolled into one, but made just for your feline friend! 

Cats are naturally curious creatures. They love watching birds, chasing bugs, and sunbathing, but letting them roam outside comes with some serious risks, from traffic, to predators to exposure to diseases. A catio gives you the best of both words: your cat gets their outdoor fix, and you get peace of mind knowing they’re safe. 

Whether it’s a simple window box or an elaborate multilevel play space connected to your home, the main goal is the same: to enrich your cat's life in a secure, enriching environment.

Benefits of a Catio


Adding a catio to your home isn’t just a treat for your cat, it comes with perks for you too. Here are just a few reasons cat lovers are falling in love with catios: 

  • Safe Outdoor Access: Your cat gets the sights, smells, and stimulation of the outdoors, without the dangers that come with free roaming. 
  • Reduces Undesirable Behaviors: Cats with outdoor enrichment tend to be more content and less likely to develop behavioral problems like aggression, spraying, or destructive scratching. See our blog about common cat behavior issues here!
  • Encourages Exercise and Play: Climbing shelves, cubbies, and vertical elements in catios help keep your cat active, and mentally stimulated. See our blog here about cat enrichment.
  • Fresh Air for Indoor Cats: Cats love lounging in the sun, and watching the world go by. A catio provides them a safe way to do just that everyday. 
  • Stress Reduction: Having a space that’s “theirs” can help reduce stress for shy, or anxious cats, especially in multi-pet households.

    Catios are a fun, functional way to show your cat some love, and they make for a great DIY weekend project, or a thoughtful investment if you’re buying one pre-kitted. In the next section, we’ll explore some creative catio ideas to inspire your build! 

Catio Ideas to Inspire Your DIY Build

Covered porches make the perfect spot for a catio. Since the roof is already in place, you only need to enclose the sides, making installation simpler and more cost-effective. Being attached to the house means you can easily add a pet door, giving your cats 24/7 access to the outdoors without you needing to open a door for them. Plus, a covered porch offers natural shade and protection from rain, keeping the space comfortable in all weather while you enjoy peace of mind knowing your cats are safe.

Consider building Tunnels to Provide Cat Only Sections

By adding tunnels that run through the cat enclosure, we created a space that’s exclusively for the cats while still allowing the rest of the area to remain open for people. These tunnels extend beyond the patio, giving the cats their own private run while leaving a comfortable, pet-free spot where people can relax and enjoy the outdoors. It’s the best of both worlds. Cats get adventure and safety, and people get an uncluttered place to hang out.

Create Multiple Routes

Incorporating multiple routes around the catio keeps your cats engaged, confident, and active. Cats love to explore and choose their own paths, so having more than one way to navigate the space prevents boredom and reduces territorial disputes—especially in multi-cat households. Multiple routes also give shy cats a way to avoid more dominant ones, making the catio a peaceful and enriching environment for everyone.

Long-Lasting Wood Protection with Outdoor Paint

Outdoor cat furniture faces constant exposure to sun, rain, and temperature changes, which can cause wood to fade, crack, or warp over time. Using a durable outdoor paint helps seal the surface, protecting it from moisture damage and UV rays while keeping it looking fresh and vibrant. This not only extends the life of the furniture but also ensures your cats always have a safe, sturdy, and attractive space to enjoy outdoors.

Shelter from the Storm: Roofing Your Catio

Adding a roof to your catio keeps your cats dry and comfortable during rainy days while also protecting the wood from moisture damage. By shielding both your pets and the structure from the elements, you’ll extend the life of your catio and ensure it stays safe, sturdy, and inviting year-round.

The Under-Deck Catio Your Cats Will Love

Building a catio under a deck is a smart way to turn unused space into a safe, enriching spot for your cats. Since the deck above already acts as a built-in roof, you get instant protection from rain, and snow so your cats can enjoy the outdoors in comfort all year long.

A Barrier Against Wind and Snow

My sister recently built this clever catio under her deck, and I thought it was too good not to share. She used clear corrugated panels along the sides to block the wind and keep snow from blowing in during the winter—making the space comfortable for her cats year-round. While I didn’t build this one myself, it’s a perfect example of how you can adapt materials and existing structures to create a cozy, weather-protected cat enclosure.

Furnishing Your Catio for Play, Climbing, and Comfort

A catio isn’t just about giving your cats safe outdoor access, it’s about creating a space they’ll truly love. Adding the right furniture and enrichment transforms it from an empty enclosure into a playground, lounge, and lookout all in one. From climbing shelves to cozy hideaways, here are ideas to make your catio a place your cats can’t get enough of.

Give Your Cats the Key to the Catio

Including a pet door makes it easy for your cats to come and go from the catio whenever they want, day or night, without you having to play doorman. It encourages more frequent use of the space, gives them freedom to explore, and allows them to enjoy fresh air and sunshine on their own schedule.

Cat Enclosure FAQs

We know there’s a lot to consider when giving your cat a safe outdoor space. From choosing the right size and materials to figuring out the best layout for climbing, lounging, and exploring, our FAQ is here to help. Whether you’re curious about safety, weather protection, or how to enrich your cat’s outdoor experience, you’ll find tips and answers to make your catio both fun and secure.

What is the best size for a catio? 

The best size depends on your available space, and your cat’s activity level. Even a small window box-style catio can offer enrichment, but if you have room, larger catios with vertical elements allow for more exercise, play and lounging options. The more space and variety you can offer, the better!

Can I build a catio if I live in an apartment?

Yes! There are many catios in apartments. Most choose to use a compact window box, secure balcony enclosures, or even custom builds that extend slightly from the sliding doors. Just make sure it's safely secured and follows your buildings guidelines. If you’re short on space, even a small screened unit can offer your cat fresh air and a view of the outdoors. See our blog here about how to catify your apartment!

Can other animals get into catios?

When built properly with secure wire mesh, and latches, catios can keep out most wildlife. A catio should keep out most predators, pests, and neighborhood pets. If you live in an area with burrowing wildlife like raccoons or opossums, avoid placing your catio directly on the ground by installing it on a raised platform, concrete, or adding flooring to the space. Be sure to use sturdy materials and routinely check for wear and tear to maintain security. 

What is the best wire to use for a catio?

Welded wire mesh is a popular durable choice for catios. It’s sturdy, chew, and weather- resistant, and can support climbing cats. Look for 16-gauge galvanized steel mesh with 1” x 1” or 1” x 2” openings for optimal visibility, and safety. There are vinyl- coated versions for added rust protection, and smoother edges. 

Another option is hardware cloth. Despite the name, it’s a type of mesh and not cloth. Opt for a 16-gauge or heavier (lower number = stronger) and ½” spacing to prevent access by small animals or paws getting stuck. It’s great for smaller or more discrete catios. 

Avoid chicken wire, or soft plastic mesh, which are not secure enough to protect your cat.
