What Is A Cat Door?

Cats are known for their often mischievous and skittish behavior, which makes many cat aficionados fall in love with them even more. While they are often depicted as dog’s worst enemy, most have a gentle temperament perfect to suit any home. Having a cat door in your home can make adjusting to the surroundings easier for your cat. 

Often, pet doors are automatically associated with dogs, however, pet doors are just as well suited for cats. This can have many wondering though, what is a cat door? Is there a difference between a cat door and a dog door? Depending on the type of door, there may not be a distinguishing between whether it’s a dog or a cat door.

A cat door is a small door that can either be placed in a wall or on a door. Often referred to as a pet flap, cat flap, or cat door, it is a small door that your cat can use to exit and enter a building or adjoining room. PetMD reminds owners that:

“Cat doors offer an excellent option for pet parents who want to manage their pet’s access to areas inside and outside the home.”

Cat doors are not to be confused with a pet gate or similar barrier, as a cat door only occupies a small opening in the wall or door it is placed in. A pet gate takes the place of a door or wall opening. Cat doors often have an array of features for your pet’s protection such as a hinged flap, weather resistance, and locking hatches.

Cat Door Features To Consider

When in search of the perfect cat door for your feline friend, it’s important to think about what features your cat would consider. For instance, if you know that your cat doesn’t enjoy squeezing through small places, try looking for a cat door with extra room for your cat.

Another feature to consider is the cat flap. This is the main component of a cat door, as it is what allows the cat to pass through whenever it uses the door. Think of it as the door essentially. Cat flaps can come in the traditional flap style, a sliding door style, and a simple open and close design. 

“Cats like being able to see where they’re going, so transparent flaps make them feel safer using the door. Soft door flaps drag along your cat’s back when she’s going through the door. Hard flaps are easier for cats to push through . . ..”

With the advancement of technology and innovation, cat doors have grown to include additional features such as electronic flaps, adjustable catches, as well as various locking mechanisms. In addition to these features, you should also consider these:

  • The type of flap (electronic, weighted, hard, soft, spring-aided)
  • The type of panels (soft vinyl, plastic, plexiglass, acrylic)
  • Time controlled
  • Sensor-equipped
  • Automation
  • The type of locking mechanism

A cat door that features a soft cat flap may be good for allowing your cat to move through the door easily. Likewise, if you prefer extra added security and protection for your cat, consider a door with a sensor or one that is time controlled

This prevents intruders from using the door and will only allow the door to operate during certain times of the day.

What Is A Cat Flap?

While the door as a whole refers to all of the components, a cat flap specifically refers to the portion of the door that allows your cat to enter and exit when preferred. A cat flap is named for the flapping movement it makes when a cat uses the door. The features specific to cat flaps have also grown to include extra security and convenience.

In addition to the concern of your cat being able to get through the door, another concern of many cat owners who have doors is intruders using it as well. Because a cat flap makes using the door easily accessible, it’s important to consider what features prevent intruders like squirrels, birds, and other curious creatures from using the cat door.

Luckily, features like an automatic locking flap and a sensor-controlled flap have lessened the chances of this occurring. 

Likewise, you can also manually lock the cat flap when it is not being used. Some cat doors even feature magnetic locks that can be unlocked with a special cat collar. Whenever the cat collar is detected, the flap will unlock.

Cat flaps come in a range of sizes and varying designs sure to make your cat’s use of the door simple and easy. Some even come big enough for a dog to use. A cat door equipped with a bigger flap is highly recommended for owners who own both a cat and a dog. 

Where To Place A Cat Door

Typically, a cat door is placed in a wall or door. This could be a garage door, a sliding door, and any other type of door suitable enough. The key aspect to consider when properly placing a cat door is the purpose that the door will serve. In addition to this, considering the best convenient place for the cat door is also an idea.

For instance, your cat may enjoy stepping outside for fresh air every now and then. In this case, you would want to install the cat door on an actual door. Doing so would give the cat easy access to the outside. If you would like to give your cat easy access to their litter box that’s in a different room, you should place the cat door in a wall.

When looking for the best spot to place a cat door, consider:

The size of your cat  This will ultimately determine the best size of cat door to get. As a result, this will also influence the size of the cat door, which will then determine how much space it takes up. Having a smaller cat comes with its perks, as the door will not need to be as big.

The size of the area  If you have a narrow door or the designated wall space isn’t large enough, you may need to reconsider where you place the cat door. Other aspects such as door frames, wall outlets, and door type should also be considered.

The size of the cat door  Taking proper measurements of the cat door is important for understanding how much space it will take up. Pet doors that are usable by both dogs and cats may be larger depending on the size of the pet it accommodates. 

Before placing the cat door, measure your cat. Once you have the proper measurements, you can find a cat door with a flap that is big enough for your cat. Whether you choose to place the cat door in a wall or door, take note of the thickness of each. If either or too thick, the cat door may not fit properly. 

How To Get A Cat Through A Cat Door

As mentioned before, some cats are naturally uneasy feeling when it comes to being introduced to new things and concepts. Being introduced to anything new, whether animal or human, can be a bit scary at times. For this reason, don’t be deterred if your cat isn’t naturally willing to use the cat door.

If your cat jumps through the door on the first try, that’s great also! For those owners of cats unwilling to use the door, it may take some training and extra encouragement to get your cat through the door. Sometimes having another pet in the home that uses the cat door is an added bonus. This can influence a reluctant cat to use the door.

For kittens especially, learning to use the cat door can be quite a daunting task. Kittens tend to be frightened of unfamiliar sounds, especially if they are newly introduced to their new surroundings. Some may also jump at the sound of the flap closing behind them or their tail getting caught as they go through the door.

Propping the cat flap open may be the best starting point in training your cat to use the door. This will allow your cat to go through without having to encounter the flap and risk getting stuck in the door. At the beginning of the process, it may take slowly guiding your cat through the door. Introducing a reinforcement like a tasty treat should help!

How to Help a Scared Cat Get Used to a Cat Door

Some cats have a harder time than others getting used to this strange new hole in the door. For them, we have a few tips to help:

  • Make sure to take it slow! Cats, like any animal, need time to get used to new objects or changes in their environment.
  • Start by taping the cat door completely open. This way, your cat (or kitten!) can walk through unimpeded. As any cat owner knows, cats hate things touching them when they don’t expect it. This helps them get past that hurdle.

Is A Cat Door for You?

It’s important to take note that not all cats like cat doors. It’s important to take note that not all cats like cat doors. Likewise, not all humans are expected to like them either. As many conveniences having a cat door can provide, there are some downsides to consider as well.

For instance, if you have an exterior and interior cat door, there’s the chance of insects and other outside pests coming into your home. This goes for harsh weather as well. While some cat doors protect against the weather, that protection isn’t always foolproof. 

Aside from these minor downsides, having a cat door may actually be beneficial to you. Think of it, you’re able to control what places of your home your cat has access to. Not only are giving your cat access to certain areas, but you’re able to manage that access in a better way. 

The only way to tell if a cat door is for you is to try it! Especially since you can’t just ask your cat directly. If you’re not up to installing a cat door before asking your cat, consider your cat’s personality type. If your cat is not fond of squeezing through smaller spaces in general, this may not be for you.

Final Thoughts

Cat doors are a great addition to any cat owner’s life, especially those who have active cats who roam often. When in search of the best cat door, it can be easy to consider your concerns and needs first. It’s important to remember, however, to consider the needs of your cat. 

Ultimately, your cat will be the one using the door, so it comes down to their personality. Some cats will take better than others, but kittens trained with them from their childhood are more likely to take to them.
