10 Best Cat Doors 2026 in the United States

The PetSafe Doggy Door for Sliding Glass Doors is an excellent choice for cat and small dog owners, especially those living in apartments or rental homes. It fits pets up to 15 pounds, with a flap sized to comfortably allow small pets through without stress or injury. Its no-cut, DIY installation is a big plus if you want to avoid tools or permanent modifications, making it ideal for renters. The adjustable height feature helps it fit a variety of sliding door sizes, adding to its flexibility. Made with a sturdy aluminum frame, it includes weather stripping and a slide-in closing panel, which provide solid weather protection to help keep drafts and rain out. The flap is flexible and tinted with magnets to help it close quietly, reducing noise when your pet uses it.

Security is well covered with a latch kit that locks the sliding door, ensuring your home stays safe even when the pet door is installed, and you can also control your pet’s access by closing the panel when needed. On the downside, the door is designed only for small pets, so larger dogs won’t fit. Some users might find the flap a bit stiff initially, requiring pets to get used to it. Also, while weatherproofing is good, extreme weather conditions might still affect the door’s performance. If you want a secure, easy-to-install pet door that won’t damage your sliding door and fits small cats or dogs, this product offers a practical and user-friendly solution.

The Endura Flap Pet Door is designed for wall installation and works well for large pets, including big dogs or cats up to 28 inches tall, thanks to its sizable 10" x 19" double flap. The use of sturdy aluminum for the frame and a flexible polymer flap ensures durability and resistance to extreme weather, from freezing cold to strong winds, making it a solid choice for year-round outdoor access. Its double flap design is energy-efficient, sealing tightly with magnets to keep drafts and noise out, which helps maintain comfortable indoor temperatures and reduces energy costs.

The door also includes a secure locking cover for added safety when you want to restrict pet access. Installation is supported by detailed instructions and a telescoping tunnel fitting walls between 2" and 7.75" thickness, but homes with thicker walls might need to consider a different model or additional parts. While it’s built tough and weatherproof, the installation process might be more involved than simpler door-mounted options, so some DIY confidence is helpful.

The magnetic seals are adjustable, which is great for training pets who might be shy at first, allowing a smoother transition. Customers rate it well for performance and durability, though it’s heavier and larger than many door-mounted pet doors, reflecting its robust construction. This product suits pet owners looking for a high-quality, insulated, and weather-resistant wall pet door that balances security, energy savings, and long-term reliability.

The SureFlap-Sure Petcare Microchip Pet Door is designed for selective entry, making it a good fit for households with multiple pets or concerns about stray animals. It uses RFID technology to read your pet’s implanted microchip, which allows for secure entry while keeping out unwanted animals. It supports various microchip formats and can store up to 32 identities, making it suitable for multi-pet homes. The door is controlled by a simple one-button programming system, and you can set curfew times for added security.

However, only the entry is restricted, while any animal can exit, which might be a limitation for some users. The door opening measures 6 11/16” by 7”, and it can be installed in doors, windows, or walls with available accessories, providing flexibility in installation options. Made from plastic and glass, the door is sturdy but might not offer top-tier weatherproofing. It operates on 4 C batteries, with an indicator for low battery, but users need to remember to replace the batteries periodically.

Weighing 3.28 pounds and with dimensions of 10.31 x 4.92 x 11.02 inches, it is relatively compact, making it suitable for small dogs and cats. While its noise level isn't specifically mentioned, some users might find the locking mechanism audible. If you are looking for a pet door that provides selective entry and is easy to program, the SureFlap-Sure Petcare Microchip Pet Door is a solid choice, with the caveat of battery management and potential weatherproofing concerns.
