Looking for a more secure way to let your cat in and out of the house when you’re not there? Consider microchip cat doors. Not only do they allow your cat the freedom to come and go as they please, but they also provide more security than a standard cat flap.
The built-in radiofrequency identification or RFID technology can be programmed to recognize your cat’s microchip or collar tag and let them – and only them – in when they return, protecting them and your home from predators, strays, and other neighborhood cats.
Let’s get into our top product picks, and if you like the idea of microchip-powered tech for your cat, check out our list of the best microchip cat feeders, too!

The handy display at the top lets you know its current operating mode and battery life status, though it can also be used with the brand’s plug-in power adaptor, and you can use both to protect against power outages.

FAQs
How do microchip cat doors work?
Microchip cat doors use radiofrequency technology to connect to your cat’s microchip or RFID (radiofrequency identification) collar tag and recognize when they’re approaching, ensuring it opens only for them and keeps your home secure from unwanted guests.
Are microchip cat doors safe?
Microchip cat doors are perfectly safe, so long as they’re set up correctly and monitored over time. However, RFID tags, like any collar tag, can fall off, and no tech product is immune to malfunctions or wear and tear. So, whilst they’re great tools for making life easier, they’re no substitute for care and attention.
Which types of doors can microchip cat doors be installed in?
Microchip cat doors can be installed in most door types, including wood, glass, and plastic doors, as well as in walls, so long as they come with the appropriate adapter kit. If you’re unsure, ask the manufacturer.
Can a microchip cat door be installed in a door with metal panels?
It depends on the manufacturer; some microchip cat doors can be installed into a door with metal panels if a special adapter kit is available. Otherwise, the metal can interfere with the signal and make it less effective.
Final Thoughts
In the ever-expanding world of pet technology, microchip cat doors are one of the best creations so far, ensuring neither freedom nor security needs to be compromised for your cat – or your home!
