The Ideal Cat Door for Your Home

The need for the best cat door arose after we discovered that the cats were going bonkers while trying to go outside. One was found hanging on the doorknob on three occasions. The others were scratching the hell out of the door, the furniture, the couch and just about anything else.

The three of them covering near the door gives you the impression that they are plotting to take over the world. And it looks very ominous. So, we decided to roll up our sleeves and get some elbow grease in the process of finding the best cat door.

Tons of research ensued. We tapped into our cat parenting network. Spoke to cat parents who had installed cat doors themselves and whether it worked for them. And as always we found that what’s being sold in bold is not always the best choice.

Top 10 Best Cat Door Reviews

If you are facing a similar conundrum, then this article will help you narrow down on an ideal cat door for your home.

Sit back and enjoy.

1. PetSafe Wall Entry Aluminum Pet Doors

Whoever said that cat doors are only meant to be installed on the front or rear doors of the house?

PetSafe’s wall entry doors allow you to create a cat access door in just about any wall of the house. That sounds like an uphill task but it is made quite simple with this all-inclusive package that avoids the need for framing.

This is a telescoping tunnel that requires minimum knowledge of carpentry. Even if you are a carpentry-noob, you can still install it in a day without breaking a sweat. That’s coming from someone who has never attempted carpentry in their lives.

This best cat flap door itself is based on a double flap system which when clubbed with the tunnel creates an air-pocket that does not compromise on the insulation system of your home. Weather drafts will not be able to find their way in.

The entry is approximately 8 ¼ inches Wide and 12 ¼ inches tall which makes it perfect for even the largest of our cats. We even tried it with our neighbor’s beagle and he was able to waltz right in.  All our cats are now using the new door and sparing our furniture and door knobs.

When not in use or when our large family is out holidaying, we use the sliding panel to secure the door and prevent access. PetSafe also sells a separate sliding door that can be used on the outside to secure the door and prevent varmint from finding their way into the house.

The only reason why someone may choose another product over this is because they find cutting a hole in the wall too cumbersome. But it is pretty simple. The package includes just about everything you need for an easy installation. That includes all the hardware, a cutting template and detailed instructions.

Best features

7. Cat Mate Electro Magnetic Cat Door

The Cat Mate Electro Magnetic Cat door is an ingeniously designed product that clubs automation with simplicity to create a very effective solution for giving pets easy access to the outside. This is an electromagnetic system that relies on a simple magnet which can be attached to your pet’s collar to automatically open the door.

What makes this so effective is that your pet can go outside from inside the home anytime without activating the cat flap. But when your pet returns to the house, the magnet is required for them to enter the home. It acts like an identifying tag that will grant them access.

This is the easiest way to restrict raccoons or possums from entering the premises if you are using this on an outside door. It works equally well for cat litter rooms and other areas of the house that are for cat-only access.

Unlike some of the other electromagnetic cat doors that we tested, the sensor on the Cat Mate was super fast and it retracted instantly. There was no lag or delay in the flap opening.

The only possible glitch that we found with this was that the magnet had to be aligned in a precise position to face the sensor. Only then does the flap get activated. If you have an active cat who likes to explore and may accidentally change the position of the magnet, then the door will remain locked. Not the best of scenarios especially if you live in cold climatic conditions.

Otherwise, this brings automation at a fraction of the price of some of the other ones that we have tested.

Best features

  • High-quality electromagnetic access system that gets activated with a magnetic collar
  • Gives your cats easy access to the outside and identifies the magnetic collar
  • Prevents possums and raccoons from entering the home
  • The package includes two magnets for two pets
  • Brush stripped to prevent insulation loss


This is the best magnetic cat door that you can buy. It is priced under $40 and works flawlessly provided that you position the magnet correctly.

8. SureFlap Microchip Cat Door

When we rescued Jerome, a cuddly little ball of fur, we had to put him up at a friend’s place for a while. He was eventually adopted by the same family. But the neighborhood that they live in has a notorious gang of bobcats that roam around at night looking for potential prey (small cats). So, they needed a system that would allow him to get out of the house at specific times and restrict access at other times.

Enter the SureFlap Microchip Cat Door which simplifies preset access times with an in-built curfew mode. Once activated and programmed, the curfew mode gets activated automatically at a preset time and the cat door is locked from both directions.

During the day time or other times, it allows the pet to go outside and automatically reads their microchip to open the flap and let them into the house. So, a raccoon trying to pry their way in will not be able to do it.

You can install this on a side wall or on just about any door without too much effort. What does take some effort is to get your cat used to it, especially if they are habituated to you opening the door for them.

The SureFlap Microchip Cat Door features a tunnel extension and the cat has to get used to popping their head/shoulder into the tunnel for the microchip data to be read. If you find that your cat freaks out, then give them some time. They will eventually figure it out. Cats are smarter than any other pets that we have owned.

If your pet is not micro chipped, then you can use the SureFlap Cat door with the SureFlap RFID collar tag that is included in the package. This is very beneficial if you only want to grant selected pets access outside or to a particular part of the house.

Best features

  • High-quality construction
  • Reads microchip data fast and accurate
