Best Outdoor Cat Enclosures and Catios (2026)
An indoor cat gets safety at the cost of the outdoors. A catio gives some of the outdoors back without taking the safety away.

Everyone in this category says they tested twenty litter boxes. We have not tested any, and we say so. What we do instead: compile the published specs, read the manuals, and do the arithmetic on what this gear costs to run and how it behaves once there is more than one cat using it. Every spec is linked to the document it came from. Prices are checked daily — last verified November 12, 2026. Here is exactly how we pick.

Keeping a cat indoors is the safe choice. It is also a choice that takes away a whole world of smells, sounds and air. A catio is the most complete way to give some of it back.
What the outdoors adds
The Ohio State Indoor Pet Initiative treats environmental enrichment as essential for indoor cats, and some of the best enrichment is simply the outdoors: moving air, birdsong, the smell of rain. A window gives a cat sight. A catio adds everything else, behind mesh.
There are three ways to do it: a fixed enclosure, a harness, and a stroller. They differ in how much training they need, how much of your time they take, and how much of the outdoors they reach.
How much space the catio actually gives
Floor: 63.8 x 24.2 = 1,544 square inches, about 10.7 square feet.
Split across the two to three cats PawHut rates it for, that is 5.4 square feet each at two and 3.6 at three — which is why the six platforms and two ramps matter. Floor alone would be tight.
Height: 99.2 inches, so the territory is stacked rather than spread. PawHut publishes a 22 lb load figure but not the wire spacing, which is the specification we would most like to see.
What the three publish
| Product | Size | Safety feature | Needs from you |
|---|---|---|---|
| PawHut Outdoor Catio, 6 platforms | 63.8" x 24.2" x 99.2" | Waterproof roof, 22 lb published load; wire spacing not published | Assembly, a secure base, ideally a window link |
| Kitty Holster Harness | XS to XL | Wide vest, hook-and-loop, metal D-ring | Training and supervised walks |
| Pet Gear Happy Trails Stroller | Interior 25" x 12" x 20.5" | Zipperless enclosed cabin | Your time, every trip |
Manufacturers' published figures. The stroller's capacity is 35 lb.
The picks
The PawHut catio is the most complete answer. It stands 99 inches, gives six platforms and two ramps of vertical territory on a small footprint, publishes a load figure when most enclosures publish none, and has a waterproof roof. What it does not publish is the wire spacing, which is the specification we would check first -- so check it on arrival. The fir frame needs treating to last outdoors and assembly is substantial. The most important decision is not the model but the connection: a catio a cat can walk into from a window gets used.
The Kitty Holster is the alternative for a cat that will accept a harness. It is a wide cotton vest rather than straps, which spreads the load over the ribs and is harder to back out of. Harness walking needs patient training and constant supervision. Our harness roundup covers fitting.
The Happy Trails stroller is for the cat that will not walk on a lead, or an older cat that should not. It gives the air and sounds of a walk inside a closed cabin, with a 35 lb capacity. Our stroller roundup compares it with the alternatives.
Setting up a catio well
- Connect it to the house. Through a window or a cat door, so the cat chooses when to go out.
- Secure the base. Anchor it so it cannot be lifted or tipped.
- Shade and water. Always, and bring the cat in during extreme heat or cold.
- Check what grows nearby. Nothing reaching through or beside the mesh should be toxic to cats.
- Inspect the mesh regularly. Look for gaps at joins, especially after storms.
If you have no outdoor space
Not every home has room for a catio. The next best thing is bringing the outdoors to a window:
- A window perch, covered in our window perch roundup.
- A bird feeder on the glass, covered in our window bird feeder page.
- A screen the cat cannot claw through, so the window can open for air. Our window screen page covers pet-resistant screening.
- An indoor pen, for a different job entirely. A pen is temporary containment rather than enrichment — introductions, fostering, supervised recovery. Our indoor cat playpens page ranks them on usable floor once a litter box is inside.

PawHut Outdoor Catio Cat Enclosure, 99 in
PawHut · Catio · Our score 7.2/10
#ad Price as of November 12, 2026. Prices move; we check daily. How we're funded.
A fir-wood catio that goes up rather than out: a published 63.8 by 24.2 inch footprint carrying six jumping platforms and two ramps to 99.2 inches, with a waterproof roof and window access.
Published specs
| Overall | 63.8" W x 24.2" D x 99.2" H |
|---|---|
| Footprint | About 10.7 sq ft |
| Platforms | Six, plus two ramps |
| Published max load | 22 lb |
| Rated for | 2 to 3 cats |
| Frame | Fir wood |
| Roof | Waterproof |
| Mesh grid | Not published |
63.8 x 24.2 inches is 1,544 square inches, about 10.7 square feet. Split across the two to three cats PawHut rates it for, that is 5.4 square feet each at two and 3.6 at three. The six platforms are what make that workable -- floor alone would be tight at three.
What the specs favor
- Publishes a load figure, which most enclosures do not
- Six platforms and two ramps give real vertical territory
- Waterproof roof
- Window access, so it can be connected to the house
What they don't
- Does not publish the wire spacing, the safety-critical specification
- The 22 lb load figure is published without saying whether it is per platform or overall
- Fir wood needs treating to last outdoors
- Assembly is substantial and it is a permanent-looking object
You cannot connect it to a window or door. A catio a cat is carried to and left in is a cage in the garden, and a supervised window perch may serve that cat better.

Kitty Holster Cat Harness
Kitty Holster · Cat harness · Our score 8.3/10
#ad Price as of November 12, 2026. Prices move; we check daily. How we're funded.
A cotton vest with wide hook-and-loop closures rather than straps, which spreads the load over the ribcage and leaves far less for a cat to twist against.
Published specs
| Sizes | XS, S/M, M/L, XL |
|---|---|
| Most common fit | S/M or M/L, per the manufacturer |
| Material | 100 percent cotton |
| Closure | Wide hook-and-loop |
| Leash attachment | Metal D-ring |
| Measuring point | Snug around the widest part of the ribcage, behind the front legs |
| Made in | USA |
A strap harness concentrates a bolting cat's force on two narrow bands. A vest spreads the same force across the whole ribcage, so no single point reaches the pressure at which a cat can lever a leg through. That is the mechanism -- not a claim about how tight you can pull it.
What the specs favor
- Vest geometry rather than straps, the design cats find hardest to reverse out of
- Four sizes, with both neck and chest ranges on the published size chart
- Cotton, so it washes and does not hold heat the way mesh does
- Metal D-ring rather than a plastic clip
What they don't
- Hook-and-loop collects fur and loses grip over time
- Cotton takes longer to dry than mesh
- Sizing needs both neck and chest, which is fiddlier than one number
You need something that goes on in five seconds. A vest is more harness to put on a cat that does not want a harness on.

Pet Gear Happy Trails No-Zip Stroller
Pet Gear · Pet stroller · Our score 7.5/10
#ad Price as of November 12, 2026. Prices move; we check daily. How we're funded.
Publishes interior as well as exterior dimensions, so you can tell whether a cat can lie down in it rather than merely fit in it.
Published specs
| Interior | 25" L x 12" W x 20.5" H |
|---|---|
| Exterior | 24.5" L x 17.75" W x 40" H |
| Capacity | 35 lb |
| Shell | 600 denier polyester |
| Entry | Zipperless |
| Features | Elevated paw rest, panoramic window, storage basket |
Sleepypod's Air publishes 21 inches of interior at full extension. This publishes 25. Four extra inches is the difference between a cat curled and a cat stretched out, which matters when the whole point is a long, slow trip rather than a short one to the vet.
What the specs favor
- Interior dimensions published, which most strollers omit
- 25 inches of interior length is more than any carrier we track
- Zipperless entry, so it opens one-handed with a cat in your other arm
- 35 lb capacity covers a cat and its bedding with room over
What they don't
- 40 inches tall, so it takes real storage space at home
- Not a car restraint and carries no crash certification
- Mesh panels are a determined cat's escape route if left unlatched
Your cat has never been outdoors. A stroller is a good answer for a cat that already wants outside and cannot walk to it; it is a stressful one for a cat that does not.
