Best Base for a Catio: Concrete, Pavers, Grass, or Deck?

Does an outdoor cat enclosure need to sit on concrete, pavers, grass, or a deck for best stability?

It doesn’t have to sit on one specific surface, but it does need a flat, firm, and well-supported base. The “best” option depends on whether you want maximum rigidity, drainage, portability, and how permanent the setup should be. In general, hard, level surfaces (concrete or properly installed pavers) are the most stable, while grass can work well with the right anchoring and a prepared pad.

Concrete: the most stable and low-maintenance

A concrete patio or slab usually provides the strongest, flattest foundation. The enclosure stays square, doors tend to align better, and you’re less likely to see wobble from shifting ground. It’s also easy to sweep and sanitize. If your enclosure will be up year-round and you want “set it and forget it” stability, concrete is typically the top pick.

Pavers: stable when installed correctly

Pavers can be nearly as stable as concrete if they’re installed over compacted base material and sand, and leveled carefully. The advantage is drainage and the ability to reconfigure later. The downside is that poorly set pavers can settle unevenly, which can twist an enclosure frame over time.

Grass: workable, but plan for ground prep and anchoring

Grass is convenient and comfortable underfoot, but soil shifts with rain, frost, and foot traffic. For better stability, create a level pad (compacted gravel is common) and consider a perimeter barrier to reduce sinking. Anchoring is important to resist wind uplift and racking, especially for tall enclosures.

A deck: solid support with extra checks

A deck can be very stable if the structure is sound and the boards are level. Confirm the deck can handle the enclosure’s footprint and any added platform weight. Use secure fastening or anti-slip measures so the enclosure doesn’t “walk” as pets move around.

FAQ

Should I anchor a catio to the ground or patio?

Anchoring is strongly recommended, especially in windy areas or for larger enclosures. Use surface-appropriate anchors (concrete anchors for slabs, ground stakes or augers for soil, or secure brackets for a deck) to prevent shifting and tipping.
