Everything you need to know about catios ā from choosing the right type to buying, building, and setting one up for maximum enrichment. Use this as your starting point and follow the links into each topic.
What Is a Catio?
A catio (cat patio) is an enclosed outdoor space that gives cats safe access to the outdoors without the mortality risk of free-roaming. Cats get fresh air, outdoor stimulation, and enrichment. You get peace of mind. It's the single best investment for an indoor cat that wants outdoor access.
Catios range from a $100 window box to a $5,000+ custom permanent build. The right option depends on your space, budget, and how much outdoor time you want your cat to have.

How to Choose the Right Catio
Four questions narrow it down fast:
- Do you rent or own? Renters should stick to portable, window box, or freestanding options that don't require permanent installation. Homeowners can consider attached permanent builds.
- Do you have a yard? No yard = window box, balcony enclosure, or portable. Yard = freestanding kit or permanent attached.
- How many cats? One cat can do well in a 4x4 ft enclosure. Two or more cats need significantly more space to avoid territorial stress.
- Supervised or independent access? Portable and basic freestanding catios are best for supervised use. Attached catios with cat doors allow independent access.

What Makes a Good Catio
- Secure wire mesh: 16-gauge galvanized welded wire, not chicken wire. Chicken wire is too weak ā cats can push through it and predators can breach it.
- Solid frame: Pressure-treated lumber or powder-coated steel. Untreated wood warps and rots within a few years.
- Escape-proof latches: Cats figure out simple latches. Use a two-step latch or padlock on any door.
- Weather protection: A covered roof section keeps the catio usable in rain and protects from direct sun.
- Enrichment: Shelves, ramps, and perches at multiple heights dramatically increase how much time cats spend in the catio.
Catio Size Guide
| Number of Cats | Minimum Size | Recommended Size |
|---|---|---|
| 1 cat | 4x4 ft (16 sq ft) | 4x8 ft (32 sq ft) |
| 2 cats | 4x8 ft (32 sq ft) | 6x8 ft (48 sq ft) |
| 3+ cats | 6x8 ft (48 sq ft) | 8x10 ft or larger |
Buying vs Building
Buy a kit if: You want something up quickly, your budget is under $600, or you don't have the tools or time for a DIY build.
Build DIY if: You need a custom size or shape, your budget is over $600 (DIY wins on cost per sq ft at larger sizes), or you want a permanent attached catio.

Setting Up Your Catio for Maximum Use
Cats use catios more when they're enriched. After installation:
- Add shelves at multiple heights ā cats prefer elevated positions
- Include a scratching post or pad
- Add cat-safe plants: catnip, cat grass, valerian
- Place a bird feeder nearby ā watching birds is high-value enrichment
- Add a weather-protected sleeping spot for year-round use
