To ensure proper ventilation and temperature control in a catio, cat owners should use mesh or wire screens that allow airflow while keeping the space secure. In extreme heat, providing shaded areas, fans, and cooling mats can help keep cats comfortable. For cold weather, incorporating insulated shelters, heated beds, and windbreaks is essential. Using weather-resistant materials and regularly monitoring the temperature can prevent discomfort and health issues. Adding removable panels or covers can offer flexibility to adjust the catio environment according to changing weather conditions. Regular maintenance ensures a safe and comfortable space year-round.
