These are smaller, simpler enclosures that typically attach directly to a window sill, providing a compact outdoor viewing platform. They are ideal for cats who enjoy short periods of outdoor observation.
Best for: Single cats in smaller living spaces, or those new to outdoor enclosures.Extended Window Boxes
Larger than basic perches, these enclosures extend further out from the window, offering more floor space for napping, stretching, and movement. They often feature mesh sides for ventilation and protection.
Best for: Cats who enjoy longer sunbathing sessions and more room to explore, suitable for one to two cats.Multi-Tiered Catios
These robust enclosures provide vertical space with multiple levels or shelves, allowing cats to climb and survey their surroundings from different vantage points. They are designed for enhanced enrichment and accommodate more active felines.

Key Buying Factors
Material Durability
We looked for enclosures constructed from robust, weather-resistant materials like powder-coated metal mesh or high-quality plastic. These materials are essential for standing up to the elements and resisting cat claws, ensuring a long-lasting and secure structure.
Security Features
A primary concern for any catio is keeping your cat safely inside and unwanted visitors out. Our team prioritized models with secure latches, sturdy frames, and fine mesh that prevents escapes while also deterring insects and potential predators.
Installation and Compatibility
We evaluated how easily each enclosure could be installed and if it required specialized tools or significant modifications to your window. Universal fit designs and adjustable brackets were considered a significant advantage for broader home compatibility.
Size and Comfort
The enclosure must provide adequate space for your cat to sit, stand, and turn around comfortably. For multiple cats, we considered larger, multi-tiered options. Internal perches or shelves were also a plus for enhancing feline comfort and enrichment.
Ventilation and Weather Protection
While allowing fresh air, an ideal catio should also offer some protection from harsh weather. We looked for designs that provide good airflow without exposing your cat directly to strong winds or heavy rain, possibly with shaded areas.
Ease of Cleaning
Maintaining hygiene is crucial for your cat's health. Our team considered how easily each enclosure could be wiped down or hosed off. Smooth, non-porous surfaces and removable components were favored for simplified cleaning routines.
Care, Cost and Maintenance
Regular Cleaning
We recommend wiping down surfaces and vacuuming or sweeping out any debris inside the enclosure at least once a week. Use pet-safe cleaners to remove dirt and grime, ensuring a hygienic environment for your cat.
Inspect for Wear
Periodically check the mesh, frame, and attachment points for any signs of wear, damage, or loosening. Early detection of issues can prevent escapes or structural failures, ensuring the long-term safety of your cat.
Seasonal Adjustments
Depending on your climate, consider adding a small, shaded area within the catio during hot months or a soft blanket during cooler periods. Ensure the enclosure provides adequate shelter from extreme weather conditions.
Our team advises introducing your cat to their new window enclosure gradually, using treats and positive reinforcement. Always supervise initial visits to ensure they are comfortable and secure, especially when first exploring their new outdoor territory.
