Benefits of Installing a Cat Door1. Freedom for Your Cat

Cats love autonomy. A cat door allows them to explore, sunbathe, or retreat indoors at their leisure, reducing stress and behavioral issues.

Modern cat doors are often insulated and weather-resistant, helping maintain your home’s internal temperature.
