Types Of Cat Doors
There are lots of different types of cat doors that can attach to different places around your home. The one you choose will depend on your cat’s needs and the easiest and most convenient place for it to be installed in your home.
Doors
Installing your cat door on a door in your home is one of the most common places to put a cat door. This can be great because a front door usually leads directly into a front yard or a back door leads directly into a back yard, so your cat has immediate access. The main thing to consider here is your door’s thickness and you will need to check the cat door properly to ensure the measurements align correctly.
Walls
Installing a cat door to a wall for wall entry is pretty similar to installing it through a door. The only difference is that a cat door installed through a wall will be a lot longer, because of the greater distance between the interior wall and the exterior wall.
Windows
There are also cat doors that can be installed through a window. These can be a lot trickier than installing a cat door through a door or a wall, and they usually come in a sliding style or sash-style. In more recent years they have been made of aluminium and tempered glass.
Sliding Doors
If you have a sliding door in your home you might choose to install the cat door onto this. This is similar to the window sliding style. They are quite easy to install and you can normally use the same track that your existing sliding door sits on.
Electronic Doors
Electronic doors normally have a sensor that detects when your cat is near the door and opens only for them. Your cat will wear a collar that has a transmitter inside, or it can be linked to your kitty’s microchip, and the electronic door opens when it receives a signal that the transmitter is nearby. Once your cat has gone through the door and has moved away from it, the electronic door will shut again and lock. These doors can be especially great if you are worried about your neighbor’s cats getting into your house or other wildlife animals — they won’t be able to do so if they don’t have the transmitter on them. These doors are also easy to install.
Things To Look For In Cat Doors
There are a few things to look for in a cat door before buying to ensure you are getting the right door for both your cat and your house.
Size
First and foremost, the size of the cat door is very important. If the door is too small, your cat won’t be able to fit through it and won’t use it. If it is too big, then it is taking up unnecessary space on your door, wall or window. Therefore, you’ll need to measure your cat and add an inch to each measurement to make sure the door is the correct size. First measure the width of your cat, and then measure their chest or torso height from their shoulder all the way down to the lowest level of their chest or tummy, whichever is lower.
Shape and Color
Cat’s have quite wide bodies so you will want to purchase a cat door that is more square-shaped, rather than a tall design. You should also buy a door with almost transparent flaps because cats like to see where they are going and you run the risk of your cat never using the door if they can’t see through it. Color-wise, you want something that’ll blend in with the surface that you attach the door to, so it doesn’t ruin the decor of your house too much.
Security
The type of security you get on your cat door depends on the area you live in. If you live in a quiet area with very few other animals or signs of large wildlife, you may not need any security on your door. This will mean that your cat can come and go as they please and you won’t need to worry about a collar or locking mechanism. However, if your neighbors have cats or you are worried about other wildlife getting into your home, you may want to install a door that has a locking system. We mentioned above that this can be an electronic door that works with a transmitter in your dog’s collar.
There are two types of locking systems — a 2-way lock and a 4-way lock. A 2-way locking cat door works by unlocking and letting your cat pass through, then locking again to ensure nothing else can get in or out. A 4-way lock also allows an in-only access or an out-only access, determined by signals it picks up form your cat’s collar. With many advanced designs today you can adjust these locking mechanisms to suit you and your cat’s needs.
Easy Installation
You don’t want to buy a cat door that is very complicated to install or takes a long time. Also, if you live in a rented property or a temporary property, you might have to take the cat door out again when you leave. Therefore, you should look for one that is easy to install or one that is only temporary if needs be.
Durability
You want the at door to be durable. If your cat is passing through it multiple times a day and it isn’t made well, it is going to break in no time. Unfortunately, there is no way to know how well a cat door is made or how durable it is going to be. You should always read the reviews of the cat door you buy to double check that it is going to be durable.
How To Install A Cat Door
Installing a cat door should be pretty easy. The manufacturers will include instructions on how to install your cat door, too. Firstly, the cat door should come with a cutting template for your door or wall. Use this to outline the pet door onto your door or wall. Then, you should cut the hole using the correct tool based on the material of your door or wall. If you are cutting into your door, it is best to take the door off it’s hinges so you can get to it more easily.
Of course, there is no way to do this if you are installing it into your wall, so you will need to cut directly into the wall using the template. You may need to add a tunnel between the walls depending on the thickness between your interior and exterior walls.
If you’re ready to find the perfect cat door for your kitty, take a look at the cat doors we recommend below on Amazon.

Best Cat Door FAQ’s
Should I let my cat outside?
This is completely up to you. Cat’s have learnt to adapt to live indoors and can stay indoors and play for many hours at a time unbothered. One of the reasons you may want to let your cat outside is to let them explore their natural instincts, such as running and jumping, climbing trees and scratching. Being outside helps to satisfy their natural hunting senses too, which may in turn make them happier animals.
However, there are also many reasons pet owners don’t want to let their cat’s outside. This can be down to other animals that are outside which may result in your cat getting hurt. Being outside they are also more prone to picking up diseases or fleas or ticks. They could also end up getting lost. Therefore, it is completely up to you as to what is going to be best for both you and your cat.
What is the difference between a dog door and a cat door?
There are not too many differences between a dog door and a cat door. They both allow animals in and out of the house and both attach to either the wall, door or window. They also come with the same locking mechanisms that can be triggered by your pet’s collar or microchip.
One of the main differences between a cat and a dog door is the size of the door. Cat’s have a wider body in relationship to their height, meaning that cat doors are generally more square than dog doors. Dog doors are normally thinner but taller, because dogs are taller than they are wider. Another difference is that cat doors are often transparent because of a cat’s natural predatory nature. Cats like to be able to see where they are going whereas this is not such an issue for dogs. Cats also don’t like their backs being touched, so cat flaps will generally be softer than the flaps on dog doors.
How big does a cat door need to be?
As we mentioned above, this depends solely on the size of your cat. While cat doors are normally square shaped, you need to measure your cat to double check you are getting the right size. If the cat door is too small your cat may still be able to fit through it (we all know cat’s can get through tiny spaces!) but they may not want to, so they might end up not using it at all. Therefore, you should definitely measure your cat to be sure.
How do I measure my cat?
We touched on this earlier. When measuring a cat, you should measure the width of your cat first. Then you can measure their chest or torso height from their shoulder all the way down to the lowest level of their chest or tummy, whichever is lower. You should add an inch to both of these measurements to be sure you are getting the right size of cat door.
How do I get my cat to use their cat door?
When you first install your cat door, your cat might be quite reluctant to use it at first. This can be frustrating especially as you’ve spent money on it and you’ve gone to the trouble of installing it. Firstly, remember to be patient with your cat as they get used to using it. Getting angry at them is not going to help, and never push or drag them through the door. You can help train them to understand how the door works by using treats, leaving treats either side of the door that they must pass through the door to get. Gradually, they will catch on to how the door works.
How does a cat door prevent other animals from coming into my home?
If you buy a regular cat door, preventing other animals from entering your home can be difficult. If your cat has access and can get through the door, other animals can too, whether it be your neighbor’s kitty or wild animals.
This is where an electronic door can be very useful. As we said above, electronic doors work by detecting a signal from a transmitter either in your cat’s collar or in their microchip. When your cat goes near the door, the door will unlock and allow them to pass through and will then lock again once they move away from the door. You can also purchase cat doors that have special mechanisms and locking systems so you can ensure your cat only goes one way, especially if you need them to stay outside for a while or if you need them inside.
Many of these cat doors allow you to customize the locking system to your needs. This way, no other animal except your cat is going to be allowed access to your home.
Conclusion
If you want to give your cat freedom of coming and going in your house but don’t want to have to be there every time to let them in and out, a cat door is for you. Available in different styles that can be placed on your door, window or wall, with many featuring locking systems that ensures only your cat has access, you can live peacefully knowing your cat can go out and explore but can get back into the house without an issue. Always remember to measure your cat properly before buying a cat door and follow the instructions carefully when installing it.
