A catio combines the safety of indoor living with the stimulation of the outdoors, making it the ideal compromise for cat owners who want to protect both their cats and local wildlife.
Catios have become the gold standard recommendation from veterinarians and cat behaviorists for providing outdoor enrichment without the risks of free roaming.
Planning Your Catio
Start by assessing available space, access points from your home, sun exposure, and local building codes. Window catios attach to existing windows. Patio catios convert existing porches or decks. Freestanding catios can be placed anywhere with a protected walkway from the house.
Size Considerations
Bigger is always better, but even a small window-box catio provides meaningful enrichment. As a minimum, each cat should have enough space to move around, stretch, and access different levels. Multi-cat households need proportionally more space to prevent crowding stress.
Material Selection
Two-by-four or two-by-two pressure-treated lumber for framing, galvanized or vinyl-coated wire mesh for walls and ceiling, and corrugated polycarbonate panels for partial roofing are standard materials. Avoid chicken wire, which predators can tear through and which has sharp edges.
Access Points
A cat door through a window or wall provides convenient access. Commercial cat doors with microchip readers prevent unauthorized entry. Some designs use a tunnel system connecting the house to a freestanding catio. Ensure all access can be secured when the catio is not in use.
Interior Design
Include multiple levels with platforms, ramps, and shelves. Add a scratching post, a hammock or bed, a litter box for extended stays, and fresh water. Cat-safe plants like cat grass and catnip add sensory enrichment. A solid roof section provides weather shelter.
Safety Checks
Inspect the completed catio for any gaps or weak points. Wire connections must be tight and secure. Ensure no toxic plants are accessible. Check that no sharp edges or protruding hardware could injure a cat. Test the structure for stability before allowing cat access.
