It’s easy to build a catio with our award winning DIY CATIO PLANS! Build one yourself…or hire a carpenter to build a catio plan for you!

Catio Spaces offers a variety of DIY CATIO PLANS that take the guesswork out of building a catio to SAVE TIME AND MONEY!

Best of all, you don’t need to be an expert carpenter. Each DIY catio plan is easy to follow and rewarding to build!

Keep your cats safe, healthy and happy in a catio, an outdoor cat enclosure, that complements your home.

Life is good in a Catio!


We offer a variety of DIY catio designs and sizes for a window, patio, deck, garden or yard. First, consider the location for your catio and how much space you have. Next, decide whether you’d like your cat to enter the catio through a cat door in a window, wall, or door. That’s the basics. If your space is limited, consider our compact Window Box™, Cat Tunnel™ or Haven™ catio plans. Looking for a catio you can enjoy too? The Sanctuary™ and Oasis™ plans are a purrfect choice with space for human seating.

DIY Catio Success Stories….what clients are saying!

“Your DIY Catio Plans were a perfect solution for us and the directions are great! Every detail was considered and the plans were easy to follow. The catio is so beautifully professional and secure. I feel safe giving my cats permanent access, even at night. People just can’t believe we built it ourselves!”
-Emily S., OR

“I’m a 55 year old nurse, and if I can do it, anyone can! I priced out several pre-built options from other companies, and just couldn’t afford it. I investigated your website and with my home improvement skills I realized I could do this. I had my husband help with holding panels for the joining panels step, but I essentially built it myself. I think it’s a fantastic option for people who really love their cat companions!”
Jacki H., WI

Between what I saw at Global Pet Expo and the products that were sent to me over the course of the year, I saw thousands of pet products in 2017. It’s hard to choose only 10 favorites, but with the help from my two product testers, and my cats (Allegra and Ruby), we’ve selected Catio Spaces’ DIY Catio Plans as one of our 10 best cat products of 2017!”
