When Nora Auston moved to a new house in Portland, Oregon, a few years ago, she鈥檇 long been thinking about building a catio. Her family had revoked roaming privileges for Bertie, 鈥渙ur grouchy old lady cat,鈥 after three strikes: Bertie had harassed a neighbor鈥檚 elderly dog, and she needed professional rescue when she got stuck 50 feet up in a redwood. And then there were the dozens of dead birds Bertie brought home. 鈥淭hat cat was a total pain in the butt outside,鈥 says Auston, who has never allowed her younger cats, Peaches and Herb, outdoors unrestrained; she鈥檚 concerned they鈥檇 cause trouble, too.聽

When the pandemic hit, Auston, an oncology nurse, needed an outlet for work pressures. 鈥淲hen I get stressed, I build things,鈥 she says. 鈥淚 think that explains the magnitude of the catio.鈥 Her pets enter their sprawling outdoor oasis through a cat door in an entryway cupboard, which leads to a sky bridge and a 20-foot-long elevated walkway and ends at a 100-square-foot structure with a fountain, tunnels, and shelves. As soon as she started construction, the cats took to it鈥攁nd caterwauled for their contractor to hurry up. 鈥淭hey were like a tiny little supervisor crew,鈥 she recalls. 鈥淲hatever section I had just completed, they鈥檇 cram up in there, stick their paws through it, and wait expectantly for me to finish the next spot.鈥澛

Now the cats spend their days snoozing in the sun, rotating perches, and observing insects and birds buzzing around the yard, safe from the reach of their claws. 鈥淚t鈥檚 really nice to see the lives they live in their catio,鈥 Auston says. 鈥淲e鈥檙e just here to serve them; that鈥檚 how they think, right?鈥 While Auston acknowledges that her catio is above and beyond, a few rules of thumb are useful for even the most modest DIY projects.聽

Plan Ahead
There鈥檚 no need to start from scratch: For plans to guide or inspire, check out and . Auston found it useful to attend the annual in Portland before starting her project; several cities host these events, in which catio owners provide the public the opportunity to see their structures up close. Auston sketched her design and calculated the cost of materials, then revised as she went, scaling back when lumber prices skyrocketed during the pandemic. The top question she gets from newbie catio builders is whether to include a litter box; she suggests prioritizing room for cats to play, since owners typically have litter boxes inside.聽

Consider Safety
While cats are safer inside than out, build with an eye toward ensuring there aren鈥檛 inadvertent hazards. The cat door gives Auston鈥檚 pets direct catio access, so there鈥檚 no risk of them getting loose if she were to carry them to it. She doesn鈥檛 provide food outside to avoid attracting coyotes or rats, and she installed cat-safe plants and covered areas for shade and protection from the elements.

Provide Enrichment
Cats need places to climb and hide, like cat trees and cubbies. 鈥淚 see a lot of catios that are empty spaces,鈥 Auston says. 鈥淓ven if you just add a cardboard box with a hole cut in it, that鈥檚 going to be a much more appealing feature.鈥 A simple shelf can provide a sunny napping perch, and exterior bird feeders and suncatchers offer additional stimulation that adds to cats鈥 contentment.

Remember You聽
Many owners like to spend time with their felines in their catio. Auston made sure there was a space for her to enjoy her morning coffee and the family to gather for al fresco happy hours with the cats. 鈥淲e all enjoy it,鈥 she says. Except maybe Bertie, who often takes advantage of everyone congregating in the catio to have the house to herself.
