If you want your cat to enjoy fresh air without roaming the neighborhood, you have probably come across two terms: catio and outdoor cat enclosure. They overlap a lot, and plenty of people use them interchangeably. But the shape of your home, the space you have and the way your cat likes to spend the day all point toward one style over another. This guide walks through the main options, from a window catio to a walk-in cat run, so you can pick the one that fits.
Catio vs. cat enclosure: what's the difference?
A catio (cat + patio) is an enclosed outdoor space built for cats. The word usually suggests somewhere furnished and lived-in: shelves to climb, a box to nap in, a roof for shade, and often a connection to the house so your cat can come and go.
An outdoor cat enclosure is the broader term. It covers everything from a simple welded-wire run on the lawn to a large multi-level structure in the yard. Enclosures are more often freestanding, and cats usually visit them with you rather than wandering out on their own.
In practice, the name matters less than two practical questions: how will your cat get in and out, and where will the structure sit?
The main types of catio for cats
Window catio
A window catio attaches to the outside of a window, so your cat steps straight from the sill into a secure lookout. It's a strong choice for houses with a ground-floor window facing the yard, and for cats who like to come and go on their own schedule.
The Window Box Catio with UV-Resistant Roof & 5 Platforms (from $359.99) is built for exactly this, with five platforms, two lounging boxes and rust-resistant steel mesh that keeps insects out. Measure your window opening before you order.
Walk-in catio
Walk-in catios are tall enough for you to step inside, which makes cleaning, rearranging and playing with your cats much easier. They suit multi-cat homes and anyone with a patio, deck or lawn to spare. If you like the height but have less floor space, a tall catio such as the Large Wooden Catio 73" Tall with 7 Platforms & 2 Resting Boxes (from $339.99) gives several cats room to climb, has a large front door for cleaning, and can stand on its own or sit against a window for indoor–outdoor access.
Outdoor cat run
A run is the classic outdoor cat enclosure: a long, secure pen, usually made from metal panels. Runs are practical for larger yards and for households that want a sturdy, simple structure. The Heavy-Duty Outdoor Cat Run with Roof & UV Cover (from $259.99) uses welded wire panels, adds a waterproof cover for shade and shelter, and comes in three sizes up to 98 inches long.
Compact catio on wheels
Short on space, or renting? A compact catio on wheels can live on a deck or balcony and roll back inside at night. The 4-Tier Outdoor Catio on Wheels with Waterproof Roof (from $239.99) has four levels, four doors for easy cleaning and a small 24.4" x 23.4" footprint.
Portable playpens and tents
If you only want occasional outdoor time, or you aren't sure your cat will enjoy it, a pop-up playpen is a low-commitment way to start. Browse our cat playpens and pop-up tents, and keep in mind that mesh playpens are for supervised use.
How to choose: six questions to ask
- Where will it go? Window, patio, deck, lawn or balcony. Measure the spot, including height, and leave room for doors to open.
- How will your cat get in? Through an open window, a cat flap in a door or wall, or carried out by you. Access shapes every other decision.
- How many cats? More cats need more levels and more than one resting spot, so nobody has to share against their will.
- Will your cat be out there alone? Anything your cat uses without you needs a solid roof, sturdy mesh and secure latches.
- Do you rent? Freestanding and wheeled designs avoid drilling into walls. Check your lease, HOA or building rules either way.
- What's your weather like? Hot summers call for shade. Wet climates call for a waterproof roof or cover.
Quick guide: which style fits which home
- House with a yard and a usable window: a window catio, or a walk-in catio placed against the window.
- Multi-cat household with outdoor space: a walk-in catio or a long run with several platforms.
- Apartment or balcony: a compact catio on wheels, or cat netting to turn the whole balcony into a catio.
- Not sure yet: start with a pop-up playpen and watch how your cat reacts to being outside.
Safety checklist for any catio or enclosure
Whichever style you choose, a few simple checks make a big difference:
- Gaps: look along the base, the corners and the roofline. If your cat can fit their head through a gap, close it.
- Doors and latches: close every door fully and check the latches each time you leave.
- Stability: place the structure on level ground, and secure it if your area gets strong wind.
- Shade and water: provide a shaded corner and fresh water every time your cat is out, especially in warm weather.
- Plants: keep anything toxic to cats out of reach, both inside the catio and around it.
- Supervision: stay nearby for the first few sessions until you know how your cat behaves in the new space.
- Regular checks: inspect mesh, fixings and roof covers for wear every few weeks.
Help your cat feel at home
A catio only works if your cat wants to use it. Add a familiar blanket or bed, scatter a few treats on the platforms and keep the first visits short. Climbing levels and an enclosed resting box give your cat both a lookout and a place to tuck away, which helps cautious cats settle in.
Some cats take to a catio on day one. Others need several calm visits before they relax. Let your cat set the pace, and never shut a nervous cat in and walk away.

Frequently asked questions
Is a catio the same as an outdoor cat enclosure?
Mostly, yes. "Catio" usually describes a furnished space connected to the home, while "outdoor cat enclosure" covers any secure outdoor pen, including freestanding runs. Both give your cat outdoor time without roaming.
Can I set up a catio on a balcony?
Yes. You can place a compact freestanding catio on the balcony, or enclose the balcony itself with cat netting. Check your building's rules before attaching anything to walls or railings.
Do I need a cat door for a catio?
Only if you want your cat to come and go without you. A window catio, or a catio placed against a door, pairs well with a lockable cat flap so you control when the catio is open.
Can my cat stay in the catio overnight?
We recommend bringing your cat inside at night and during extreme weather. A catio is meant for times when you're home and can check on your cat.
How much space does a catio need?
Less than you might think. Compact catios fit on a balcony or deck, while walk-in models need a patio or a patch of lawn. Measure your space, including height, compare it with the details on each product page, and email us if a measurement you need isn't listed.
