Frequently Asked Questions

How long does shipping take?

Orders are processed within 1–2 business days. Standard shipping to the US typically arrives in 3–7 business days. You will receive a tracking number by email as soon as your order ships.

Is assembly required?

No tools are needed. Our collapsible tunnels and playpens pop open in seconds, and catio kits click together in minutes. First-time assembly may take a little longer while you get used to how the mesh wraps over the frame — reviewers tell us it gets much easier on the second attempt.

How do I clean it?

Spot-clean with a damp cloth and mild soap. Most of our collapsible tunnels and playpens can be wiped down easily; fabric parts can be hand-washed and air-dried. Always let everything dry fully before folding it away.

Will it fit on my balcony or patio?

Yes for most standard balconies and patios. Reviewers with apartment balconies describe the Compact Kit as "fits perfectly on most balconies", while the Mega Kit is "really big for a click-together cat enclosure" and is best placed on a larger balcony, patio or in a garden. Check the dimensions above against your space before ordering.

Is it safe for outdoor use, and will the mesh hold up?

Yes. The mesh is made to withstand normal scratching, jumping and climbing — one reviewer says her cat "claws at it and it doesn't tear or rip", even when he jumps at squirrels. We still recommend placing the catio on a flat, level surface and supervising outdoor time at first.

Can I connect two catios together or add a tunnel?

Yes. Our catio kits are designed to connect to each other and to Kittyus tunnels using the included connector parts, so you can build a larger run or add a tunnel link as your cat's territory grows.

Can one person set it up, and how long does it take?

Yes, most customers assemble their catio alone in 15–30 minutes. A few Amazon reviewers of similar enclosures mention that a second pair of hands makes the first build easier — especially when stretching the mesh over the frame. Everything clicks or hooks together without tools.

Will it fit through a standard doorway?

Check the assembled dimensions above against your doorway before ordering. Some similar enclosures on the market are too wide to fit through an interior door once assembled, so customers who plan to move it indoors and outdoors usually measure first.

How does it hold up in hot weather and direct sun?

For best results, place the catio in a shaded or partially shaded spot. Reviewers of other mesh enclosures note that frames can soften and warp when left in intense direct heat all day, and mesh ages faster in full sun, so shade extends the life of any enclosure.

Is it really escape-proof?

Our catio uses zippered, closable openings and secure mesh. No enclosure can be 100% escape-proof if a cat is determined, so we recommend supervising outdoor time at first — one Amazon reviewer of a similar product lost a cat that found a way out through a door gap. Close all zippers fully and check the seams regularly.

Are all the pipes and connectors included? How do I check?

Your kit ships with every pipe and connector needed for the model on this page, and the included instruction sheet lists the exact piece count. Reviewers of similar enclosures found counting pieces before assembly worth the few minutes — a handful reported being short on pipes or needing to double-check the count, so verifying against the checklist first saves frustration. If anything is missing, contact us and we will ship it.

I have weaker hands — is assembly manageable?

Assembly is tool-free, but the connectors do need firm, even pressure to lock into place. Reviewers of comparable kits say a second person makes the first build noticeably easier, and one 71-year-old reviewer of a very similar enclosure assembled it on her own with concentration and effort. Take it slowly, press connectors in straight, and it goes together in 15–30 minutes.

Will the platforms and hammocks hold a heavier cat?

The platforms are designed for kittens and average adult cats. Reviewers of a similar enclosure warned that perches can rip sooner under very heavy cats, so if your cat is notably heavy, we recommend supervising first use and reinforcing the platforms with the included attachments.

How durable are the zippers over time?

We use reinforced zippers, and with normal use they hold up well — one long-term reviewer of a similar enclosure said the frame and structure were still perfect after 18 months. Zippers can wear faster if closed while fabric or mesh is caught in the track, so zip gently and check the track before closing.
