8 Best Collar Activated Cat Door 2025 in the United States

The Power Pet Large Electronic Pet Door PX-2 is designed primarily for medium to large dogs, making it a solid choice for pet owners looking for a convenient way to allow their pets to come and go freely. One of its standout features is the motor-driven, vertically-sliding door, activated by an ultrasonic collar. This technology prevents the door from opening unless your pet is approaching directly, which minimizes accidental openings and drafts, enhancing comfort and efficiency.

The door offers versatile access control with four options: In Only, Out Only, Full Access, or Closed & Locked. This flexibility is great for managing your pet's movements based on your preferences.

Weather resistance is another strong point. The door is wind and weatherproof, featuring an airtight seal and an automatic deadbolt lock, providing a high level of security against outside elements and ensuring that your home stays safe.

The Plexidor Performance Electronic Dog Door is designed primarily for large pets, accommodating dogs up to 125 pounds. This door stands out with its collar-activated mechanism, which ensures that only pets wearing the special collar can enter or exit, enhancing security. Its robust construction from stainless steel gives it durability, making it a long-lasting choice for your home. The door's dimensions allow for installation in various exterior doors up to 12 inches thick, which adds versatility for homeowners. It’s also American-made and comes with a five-year warranty, providing significant peace of mind.

One of the main advantages of the Plexidor door is its ease of access, allowing your pets to enjoy the outdoors without needing your assistance. The smart label technology ensures that the door operates securely, preventing unwanted animals from entering. However, this door's focus on larger dogs may not suit cat owners looking for a more compact option. Installation might be straightforward for some, but those who are not handy may face challenges, especially with the requirement for fitting into thicker doors.

The door’s weather resistance is another highlight, helping to keep your home protected from the elements. The Plexidor Performance Electronic Dog Door is a reliable and secure option for large pet owners seeking an automatic solution. Its specific design may limit its appeal for those with smaller pets, and the installation might require a bit of DIY expertise.

The SureFlap Microchip Pet Door is designed for pet owners looking for a secure and selective way for their cats or small dogs to enter and exit without allowing other animals access. One of its standout features is its RFID activation mechanism, which reads your pet's implanted microchip, ensuring that only your pet can use the door. This is excellent for preventing stray animals from coming inside. Additionally, it can learn up to 32 microchip identities and offers a simple one-button programming feature, making it user-friendly.

The door’s dimensions of 6 11/16” high by 7” wide are suitable for smaller pets, and it can be installed in various locations such as doors, windows, or walls, which adds versatility. The battery-powered operation (using 4 C batteries) is convenient, with an estimated battery life of up to 12 months. A low battery indicator is a nice touch, alerting you when it’s time to replace them.

Some users may find the installation process a bit challenging, especially if they are not handy. The need for batteries, while common, means an ongoing cost and maintenance concern that some pet owners might prefer to avoid. Additionally, the door is specifically designed for small pets, so larger animals won't benefit from this product. While it offers good weather resistance, extreme weather conditions might still pose a challenge. This product is a fantastic choice for cat lovers and owners of small dog breeds looking for a secure, well-thought-out pet door solution, but potential buyers should consider the installation complexity and battery usage before making a purchase.
