Why Should You Choose Your Cat Door Carefully?

Selecting the best cat door for your pet could be quite confusing, due to the vast diversity of products. Still, this doesn’t mean that you should take this decision lightly.

The item you select should be right for your pet, in terms of size and comfort. On that note, you should also think about the space to install it. What would your companion prefer a window, a door or wall cat door?

Assessing the size of your cat is also highly recommended for the best results. Truth be told, you’ll install a pet door only once, which means it should stick and reach its purpose from the very beginning.

Here are the aspects we find to be primordial when you’re in the market for the best cat door.

What To Look For When Choosing Your Cat Door?

Material and safety are the most important things to consider before making a purchase.


For starters, bear in mind that installing a cat door requires cutting a hole in the wall, door or window. That’s why it should be made of high-quality material.

Overall quality and build are equally important. Plastic and PVC are two common choices of materials. Vinyl is another popular choice; however, it won’t keep unwanted intruders at a distance (such as raccoons or stray cats).

For instance, if you live in an area with extreme temperatures, you should select a product that would keep the cold out (or the heat).

Truth be told, not all cat doors are made to withstand cold weather. The hard plastic could become brittle in temperatures below zero. Consequently, the cat door is likely to crack or break.

In addition, certain mechanisms could fail in cold weather. Extreme temperatures make the door stiff, preventing it from opening properly. This could lock your little companion outside.

On the other hand, if you live in an area with tremendously hot summers, the risks are different. The plastic may deform if the temperatures are too high. This, of course, could lead to malfunctions.

Keeping your cat safe in such instances is primordial. On that note, perhaps you should consider an automated cat door, so that you could control when your pet leaves the house. A magnetic cat door could be handy as well.

In short, the quality and the material of the door could reduce heating or cooling, keeping out bugs, slugs, and other intruders.


Another crucial consideration when it comes to picking the best cat door is safety. You want to grant your little companion the freedom to explore the outdoors, but you also want to ensure its safety at all times.

On that note, selecting an electronic cat door could be the best decision. These devices are automatic, which means they are more convenient, in comparison with other models.

These work in association with your pet’s collar. It unlocks only when your cat attempts to enter the house.

If your pet’s safety is a primary concern as you live in an area with predators or extreme weather conditions, this could be your best pick in terms of security.

Apart from that, you could control the hours when your cat could go outside. For example, a microchip cat door unlocks only in contact with the pet’s microchip.

Moreover, there are pet doors with infrared locks, which open only if the collar-mounted device delivers the correct code to the receiver. This enables owners to have multiple flaps for more than one pet.

You can select whether you allow a pet outside or not (if one is ill, disabled, the weather is inappropriate, so on and so forth).

To sum up, automated or electronic cat doors are recommended if you want to ensure your pet’s safety at all times. Plus, this could prevent burglars from having access to your house, as well as other unwanted incidents.

The downside is that these products could be pricier than other options.

Our Recommendations

Considering that your pet’s needs differ, the market provides a variety of products that could pass off as the best cat door. In that direction, we have five excellent options for you.

The main advantage of this cat door window insert is that it fits easily. In addition to that, installing it isn’t that challenging. We encountered no difficulties whatsoever in putting it on, which is a great plus.

However, fitting in the cat door according to your liking could take a while. The window sash has springs on every side. This enables you to push the sides in. As you let go, they stretch back out, fitting the window perfectly.

By using the small silver knobs, you can tighten the mechanism as you wish so that the window sash stays put. As you can see, the installation process appears to be simple. And it actually is, with one exception.

It could take a while to get the sides in place. The white plastic frame should prevent creating a large gap, letting air in and out.

Secondly, the aluminum construction guarantees that this is a high-quality, long-lasting product that would withstand the test of time.

The amount of air that enters or leaves the room is minimal, compared to opening and closing the doors all day long.

Installing the door a little bit higher off the ground is an excellent tip. It minimizes the likelihood of raccoons or possums making an unwanted visit.

Still, we wouldn’t recommend this if you’re living in an area with extreme temperatures. This particular item is quite drafty. What you could do is place a weatherizing plastic film over the door, which could help with cold air leaks.

The clear vinyl flap is the simplest model. We would suggest you to get durable ChubbyKat door models.
