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 Cat Flap is a convenient solution for cat owners looking to control their pets' entry and exit without worrying about stray animals. One of its key strengths is its selective entry feature, which uses RFID technology to read your cat’s microchip, ensuring only your pet can access the door. It supports up to 32 microchip IDs, making it suitable for multi-cat households.

If your cat isn’t microchipped, RFID collar tags can be purchased separately. Programming the device is straightforward with its single-button setup. The door’s opening of 4 3/4” (H) by 5 5/8” (W) fits well for most cats and can be installed in various locations, including doors, windows, and walls. This flexibility is a big plus for different home setups. Powered by 4 AA batteries, it boasts an impressive battery life of up to 12 months, with a low battery indicator to alert you when it’s time for a change. The weather-resistant design ensures durability in different conditions.

It’s important to note that the batteries are not included, which could be an inconvenience. Additionally, while the flap is secure, it might not deter very determined intruders. The plastic frame may not be as sturdy as some metal alternatives. Nonetheless, this cat flap serves as a thoughtful gift for cat lovers, backed by a three-year warranty for added peace of mind. It’s an excellent choice for those wanting a hassle-free, secure pet door solution.
