Catios are enclosed outdoor patios for cats, and sometimes their humans, designed to keep cats safe while enriching their lives in the great outdoors. Catios come in a variety of designs and sizes, from a small window box to a large back yard enclosure, that add a unique feature to your home and provide a safe outdoor space that supports your cat’s happiness and well-being.

While being outside provides stimulation and enrichment, the dangers of the outdoors puts free-roaming cats at risk and poses a serious threat to wildlife. Catios are the perfect compromise, giving cats the enrichment they crave while keeping them away from wildlife and other dangers.

Catios are becoming increasingly popular around the world as cat parents seek peace of mind while satisfying their cat’s natural instincts to be outdoors.

Should I consider a catio?

There are many benefits of catios including protecting wildlife, reducing common behavioral challenges and deepening the relationship between you and your cat. Multi-cat families can face challenges such as territorial conflicts. Catios can help issues like cat aggression or even help keep door-dashers from escaping. They can also be fantastic for senior and special-needs cats, or any feline who longs to feel the wind in their whiskers.

Every cat is unique both in personality and behavior. If your cat is becoming destructive, bored, fighting, gaining weight or using your indoor plants as litter boxes, it might be #timetogetacatio. There are many signs that your cat needs a catio.

“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 that I feel safe giving my cats permanent access, even at night. People just can’t believe we built it ourselves!”

Your catio plans were super easy to follow and it turned in to being a great weekend project. The finished catio looks, and is, like an extension of our house. Our little felines took a quick liking to it and the catio has given my wife and I peace of mind. Thank you from the bottom of our hearts for the DIY plans and giving our cats the freedom to enjoy the outdoors in a safe environment!
