Keeping cats safely outdoors in Houston is a genuine challenge — not just because cats are accomplished escape artists, but because Harris County's urban coyote population poses a real and serious threat to outdoor cats. Griffin Fence specializes in cat containment systems: small-mesh cat-proof fencing, inward-angled overhang systems, and complete catio enclosures.
Get a Free Cat Fence EstimateContaining a cat outdoors presents a fundamentally different engineering problem than containing a dog. Dogs are runners and diggers — a fence tall enough and buried deep enough at the base will generally contain a dog. Cats are climbers. A standard 6-foot cedar wood privacy fence that perfectly contains a German Shepherd presents essentially no barrier to a determined cat. A cat that wants to be on the other side of a standard fence will be on the other side of a standard fence.

The physical challenges cats pose to standard fencing:
Effective cat containment requires a different approach: surfaces that prevent climbing by using inward angles the cat cannot overcome, or complete enclosures that remove the escape option entirely.
Harris County has a significant urban coyote population that is present throughout the metro — not just in the outer suburbs. Coyotes have been documented in Katy, Cypress, The Woodlands, Pearland, Sugar Land, Spring, and even within the Loop in some Houston neighborhoods. They are active primarily at dawn, dusk, and nighttime, which correlates with the times many cats go outdoors.
Coyotes actively hunt outdoor cats in Houston suburban environments. This is well-documented by Harris County Precinct wildlife management and reported regularly in community social media groups throughout the metro. A cat that is not contained is at risk whenever it is outdoors near dawn or dusk in virtually any Houston-area neighborhood.

A properly designed cat containment fence serves a dual purpose: it keeps your cat inside the yard, and it keeps coyotes from accessing your cat while it is in the yard. The same inward-angled system that prevents cats from climbing out also helps prevent coyotes from climbing in.
Griffin Fence builds cat containment systems using specialized small-mesh chain link and custom structural components. Our approach is confirmed from our experience with these systems and from the needs of Houston cat owners who require reliable containment.
For properties with an existing fence, the most economical option is adding a cat-proof topper to the existing perimeter. Griffin Fence installs angled arm brackets at the top of fence posts — the arms extend inward at a 45-degree or greater angle toward the interior of the yard. A mesh or flexible barrier is attached to these arms, creating an inward-curving overhang that prevents cats from climbing over the top.
When a cat reaches the top of the fence and attempts to continue climbing, the inward angle of the overhang reverses the direction they would need to climb — they cannot get a grip on a surface that is coming back toward them. Most cats abandon the attempt and return to the yard.
Permit Check: Houston city limits don’t require permits for residential fences under 8 ft. Fort Bend County requires permits over 6 ft. HOA approval is separate from city permits.
This system can be added to existing wooden privacy fences, chain link fence Houston, TXs, and masonry walls.
For property owners who want complete containment certainty, a fully enclosed cat yard — chain link on all sides and over the top — eliminates all escape possibility. The enclosure is built with 1-inch or smaller mesh chain link to prevent cats from getting a foothold through the mesh. A full top prevents any jumping or climbing exit.
Full enclosures are sized to cover a portion of the yard — typically a dedicated outdoor cat zone — or can encompass the entire backyard for properties where this is practical. The enclosure is constructed with proper gate access for the humans and any needed maintenance entry.
A catio is a screened outdoor enclosure attached to the house at a window, door, or cat door, allowing cats to access the outdoors within a fully contained structure without unsupervised yard access. Catios range from small window box extensions to large walk-in structures spanning an entire deck or porch.
Griffin Fence builds catios using galvanized 1-inch or smaller mesh chain link on a structural frame, sized and configured to your specific house exterior and outdoor space. Access from inside is through a cat door or a modified window or door opening.
Every cat containment project is unique. Some properties require a combination of approaches — a full perimeter topper for most of the yard with a catio attached to the main bedroom window, for example. Griffin Fence performs a site assessment at your property to design the most effective and cost-appropriate system for your specific situation.
Standard residential chain link is manufactured in 2-inch mesh — the diamond openings are 2 inches across. A cat can easily get all four paws through 2-inch mesh and climb like a ladder. Griffin Fence uses 1-inch mesh (or smaller) for cat containment applications. At 1-inch mesh, a cat cannot get a meaningful foothold through the openings, which significantly reduces climbing ability even without the overhang topper system.
Galvanized steel chain link is specified for cat systems — it provides strength and corrosion resistance appropriate for Houston's climate without the cost of vinyl-coated options for structural applications.
