Things to Consider Before Getting an Electronic Cat Door

Before purchasing an electronic cat door, take note of the following factors to ensure you’re buying the right one for you.

Door’s Directional Sensitivity

This refers to the unlocking system of the electronic door.

You don’t want the electronic cat door to open each time your pet strolls by or when your cat rests close to the entryway. A directional detecting system allows the door to smartly stay locked if it doesn’t detect your pet’s intention to go out.

Alongside this, the sensitivity of the door is important to prevent locking your cat indoors as well. Some doors either lag or don’t open at all, which deems it virtually useless.

Door Size

When selecting your pet door, don’t forget to measure your pet to ensure you’re getting the right size!

Not all pet doors can easily accommodate larger breeds of cats and dogs, and you especially don’t need a larger-than-necessary door if your cat is small. With pet doors, we’d normally cut a new hole onto our doors or wall, so it’s essential to measure the right size before going to the point of no return.

Some of the brands listed above, like the High Tech Pet Power Pet Electronic Pet Door and the PetSafe Electronic SmartDoor, come in small, medium, and large. Consider these options if you have a chubby or bigger cat, or if you have another pet like a dog in the house.


The ease of the door’s installation is another factor to consider. Most electronic cat doors come with installation guides or videos on how to install the door, but it’s inevitable to have some doors harder to install than others.

This is important because it’ll allow you to decide whether you’re going to install the door yourself or have a contractor do it for you. That, of course, requires money, so make sure it fits your budget. Standard installation may cost an average of $100-$400, depending on the size of your door.

Access Control

This refers to the control the electric door gives you. Some doors have 2-Way access control, and some have 4-Way access.

2-Way access allows two modes: completely unlocked and completely locked.

4-Way access allows four modes: completely unlocked, completely locked, in-only and out-only access.

Microchip or SmartKey

A cat’s microchip is implanted through a syringe underneath the skin and is more or less permanent. SmartKeys, on the other hand, comes with a built-in chip inside your cat’s collar, and, can be removed at any time.

Some sat doors come with microchip-only compatible, SmartKey-only compatible, like PetSafe’s Electronic Smart Door, and with both, like the Sure Petcare and Cat Mate Microchip Cat Flap

Make sure what’s best for you before buying a cat door, as this will be your cat’s main “key” of identification.

Frequently Asked Questions

Know a little more about electronic cat doors here.

How do you know which size cat door to get for your cat?

Follow these three steps:

Step 1: Measure the width of your cat, making sure you’re measuring the widest part which is commonly the chest of hips.

Step 2: Measure your cat’s height from her shoulders to the bottom of her chest or belly, whichever taller.

Step 3: Select the size of the door based on your cat’s weight and height, making sure to give the door a few inches in between.

Are Electronic Cat Doors better than Manual Doors?

Both doors serve their purpose, but electronic pet doors have something manual doors don’t: security.

Electronic pet doors only unlock when they detect your dog or cat, which ensures rodents and unwanted strays out of your house. They also have automatic locking features that you can easily control.

The only downside is that they can be a bit pricey. However, with every good product, there comes a price.  And your pet’s security should come second to none.

Are Electronic Doors a safety risk?

Electronic doors are made with the utmost security and safety in mind. These doors, once locked, can’t be opened. It acts as burglar barriers as well, especially since it’s made of very hard plastic or metal.

The aluminum frames that oftentimes surround the electronic door, provide security themselves.
