So you want to keep your cat indoors and out of harm's way, but you've noticed them staring longingly out the window — especially as the weather turns warmer and more critters are out and about. A DIY cat enclosure offers the best of both worlds. Cat patios, or "catios," let your cat relish the great outdoors with grass under their paws and the breeze on their fur.
Walking your cat outside on a cat halter and leash offers many benefits, too, but it can take some time to get used to. Learning how to build a catio opens up the world to your cat, which can lower stress, relieve boredom and improve overall health.
What Is a Catio?
A portmanteau of "cat" and "patio," catios come in many sizes and configurations with one overarching purpose: to provide a safe outdoor experience for cats with a protective barrier that keeps danger at bay. You can purchase a ready-made catio, but learning how to build a catio yourself has advantages. Namely, you get to design the perfect DIY cat enclosure for your cat's needs — and take pride in your accomplishment.

How Can Catios Benefit Your Cat?
Catios allow your cat to enjoy the benefits of the outdoors without many of the usual risks. Providing your cat with a secure outdoor enclosure also protects bunnies, birds and squirrels from your mighty feline hunter.
Keeps Cats Safe Outdoors
Free roaming is associated with significant risks for cats. Many veterinarians encourage cat lovers to keep their cats exclusively indoors for safety reasons. Cats who roam outside can become lost, encounter dangerous wildlife, like coyotes, and catch parasites or other diseases from feral cats. They may also get into conflicts with cats or other animals and become wounded.
And then there's cars. According to one review of the risks associated with free-roaming cats, traffic accidents pose the largest risk, reporting a 70% fatality rate for cats involved in traffic accidents. Outdoor cats' higher risk of injury or death from car accidents, animal attacks and diseases can all contribute to shorter lifespans.
Provides Environmental Enrichment
While indoor confinement keeps cats safe, it can also increase stress by inhibiting their ability to explore, hunt and play. If you have multiple indoor cats, crowding increases the potential for unwanted behaviors, including inter-cat aggression and litter box problems.
Environmental enrichment provides indoor-only cats with resources that help alleviate stress and improve quality of life at any age. Enrichment supports cats' sensory experiences, encouraging them to play, scratch, bite, sniff out fun smells and engage with the world around them. For example, you can offer your cat a box of crunchy leaves to play in or a puzzle toy filled with healthy treats.
Catios offer an even more intense natural experience for your cat. From the security of their DIY cat enclosure, they can encounter fresh scents; nibble treats or cat grass; watch and chase bugs; and feel the wind ruffling their fur.
