Custom Catio Builder for Your Home

A catio is a custom-designed outdoor enclosure that gives your cats safe access to fresh air, sunshine, and outdoor stimulation — while keeping them protected from traffic, predators, and other hazards. They range from compact window boxes to large multi-level structures with platforms, ramps, bridges, and cozy hideaways. Think of it as a screened-in patio designed specifically for your cats.

Projects vary based on size, materials, features, and site conditions. Indoor cat walls are the most affordable option, while large multi-level outdoor catios represent a bigger investment. Window box catios fall somewhere in between. Every project receives a detailed, transparent quote after a free consultation — so there are never surprises. We're happy to work within a range of budgets.

Yes. Monument Catios is a fully licensed and insured design-build firm. We hold an Arizona ROC License (#364641), a Maryland MHIC License (#167535-02), and a Pennsylvania Home Improvement Contractor Registration (#PA214722). We handle everything — custom 3D design, permitting, materials, and professional construction — under one roof. One company, one contract, one team responsible for your entire project from start to finish.

We currently serve Arizona, Maryland, Pennsylvania, and North Carolina. In Arizona, we cover 26+ cities including Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Tucson, Flagstaff, and many more across the Phoenix metro and beyond.

Contact us to confirm service availability in your specific area.

Typical timeline is 4-8 weeks from initial consultation to your cats enjoying their new space. This includes design development (1-2 weeks), permitting and HOA approval (1-3 weeks), and professional installation by our licensed crew (1-5 days depending on complexity). We provide a detailed timeline during your free consultation so you know exactly what to expect.

Permit requirements vary by city and county. Many municipalities require permits for permanent outdoor structures attached to homes. The good news: as a licensed contractor, we handle the entire permit process for you. Our team prepares all application documentation and works directly with the local building department throughout the process. You don't have to worry about paperwork or compliance.

Absolutely — that's the whole point. Every Monument Catios project is 100% custom-designed to complement your home's architecture, whether it's a Southwest adobe in Arizona, a colonial in Maryland, a modern build, or anything in between. We create detailed 3D renderings so you can visualize the design before any work begins. Unlimited design revisions ensure you love the final concept.

Yes. We engineer every enclosure for the specific wildlife threats in your area. In Arizona, that means heavy-gauge screening designed to deter coyotes, secure locking mechanisms, and structural designs that help protect against bobcats, javelinas, rattlesnakes, and hawks. In Maryland, we design for raccoons, foxes, hawks, and other local predators. In Pennsylvania, designs account for coyotes, hawks, great horned owls, and black bears. In North Carolina, we design for coyotes — now in all 100 counties — plus hawks, owls, black bears, and copperheads. Your cats' safety is our top priority and non-negotiable.

Yes. Alongside catios and cat walls, we design and build custom dog runs, chicken coops, duck coops, backyard aviaries, and tortoise enclosures — all to the same predator-proof standard, by the same licensed crews (AZ ROC #364641, MD MHIC #167535-02, PA HIC #PA214722), under one contract.
