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.

The PetSafe Never Rust Wall Entry Pet Door is designed for both cats and small dogs, with a flap opening size of 5 1/4 inches wide by 8 1/8 inches high, suitable for pets up to 15 lbs. Made from durable plastic, this pet door offers a significant advantage over metal doors as it doesn't rust and provides better insulation. The use of PVC for the frame ensures it can withstand UV exposure, adding to its longevity. The telescoping tunnel design makes it adaptable for wall installations of varying thicknesses (4 3/4 to 7 1/4 inches), with extension kits available for even thicker walls. This makes it a versatile option for different home setups where door installation may not be feasible.

One of the standout features is its energy efficiency, thanks to the double-flap system that provides excellent weatherproofing and insulation, helping to maintain indoor temperatures. Additionally, the slide-in closing panel offers extra insulation when the door is not in use, which is a thoughtful touch for energy-conscious users. DIY enthusiasts will appreciate the ease of installation, as the product comes with a cutting template and detailed instructions. However, some users may find the DIY aspect challenging if they are not comfortable with basic home improvement tasks.

While the plastic construction is durable, it may not match the aesthetic of all homes, and some users might prefer a more premium material. Noise levels are generally low, but the flap could make some noise when pets use the door, which might be a consideration for light sleepers or those sensitive to noise. In conclusion, the PetSafe Never Rust Wall Entry Pet Door offers a practical, durable, and energy-efficient solution for pet owners, with the main drawbacks being aesthetic preferences and potential installation challenges for less handy individuals.

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.

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.
