Considerations When Choosing The Best Cat Door:

To get the perfect cat door for your pet, it’s advisable to do a little more than reading through a guide. It’s also important to consider factors such as the weight of your cat, the thickness of your interior doors, the behavior of your pet, and so on.

Putting in that extra effort to bring all possible factors into consideration will go a long way in helping you get the interior cat door that works best for both you and your cat.

Your cat deserves the best. You deserve the best, too! Look For The Type of Cat Flap That Best Suits Your Needs. There are different types of cat flaps available in the market. The most common ones are:

Lockable cat flap:

The lockable cat flap comes in two varieties: a 4-way lockable cat flap and a 2-way lockable cat flap. The 2-way cat flap comes with the regular “locked/unlocked” feature, while the 4-way cat flap features an “in-only/out-only” door design.

This means that if your kitty is out playing, you can set the 4-way cat flap to in-only mode. Activating this setting will ensure that once your cat comes back in, it won’t be able to go back outside. You can also apply this setting the other way round.

Traditional cat flap:

This simple, two-way cat flap allows your kitty to move conveniently from inside your home to the stimulating outdoors. This type of cat flaps are highly affordable, hence suitable for anyone on a strict budget. Unfortunately, traditional cat flaps have one downside: they give other cats or pets in the neighborhood easy access into your home.

Magnetic cat flap:

Magnetic cat flaps feature a magnetic tag or special collar that gives access to your beautiful kitty. The function of the magnet is to unlock the cat door to grant your pet free passage. These cat flaps feature a four-way locking system, too.

Infrared cat flap:

The infrared cat flaps come with an infrared transmitter that your kitty wears around the collar. This transmitter is responsible for sending a signal to the cat door, prompting it to open for only your cat.

If your goal is to prevent other cats and pets from getting into your home, then you should consider choosing the infrared cat flap. You have no cause to worry if you have more than one pet, as additional collar keys are available.

Microchip cat flap:

The microchip cat flap is similar to the infrared cat flap, as it also comes with a sensor tag. This cat flap allows your cat to enter or exit via the door. Some doors give you the option to program what time you want your kitty to go out.

This means that by entering a set of instructions, you can allow or deny your cat exit. The sensor tag can also be programmed to work with all your other pets. It’s worth mentioning that these extra features make this type of cat flaps quite expensive.

Decide on The Cat Door Location That’s Most Fitting

Before buying any type of cat flap, it’s important to put some thought into where it’s going to be installed. Sometimes, making up your mind about the perfect spot can be difficult.

Fortunately, you can install cat doors in different locations within your home, like for example the cat doors for glass. In that line, there’s a broad spectrum of cat doors available to choose from, as well as cat flaps for:

  • walls
  • glass doors
  • screen
  • timber doors
  • sliding glass doors

Getting the location for your cat flap installation right can help you save installation costs. Also, it’ll go a long way in giving your pet convenience. For the aforementioned reasons, be sure to do all that’s required of you to get this aspect properly handled.

Consider Your Cat’s Size:

Taking out time to measure your cat is one of the most important things to do before choosing a cat door. You don’t want to end up with a cat door that’s too small for your kitty, or big enough to let in stray pets. To get your cat’s width, use a measuring tape to measure its widest part, the hips or chest.

Add one or two inches to the measurement. For height, measure your kitty from the top of its shoulders to the bottom of its belly. Add about two inches again. With the measurements, find the cat flap that suits your cat best. If your cat is still a kitten, it’s advisable to account for its future growth.

Confirm The Ease Installation:

The ease installation varies for different cat doors. The cat door type and the area where you intend to install the cat door can both affect the installation process. Most products include a clear manual on how to install a cat door in the interior door.

For instance, getting a traditional flap door installed into wood is easier than installing it in a wall. It’s advisable to take every factor associated with ease of installation into consideration before choosing a cat door, as this will help to avoid difficulties down the line.

Decide on The Cat Flap Material:

There are many frames available in the market to choose from. A number of cat doors come in metal or plastic frames, the former being the more expensive/stronger.

If your door is usually exposed to extreme weather conditions, you should go for a metal frame, as this will make your cat door more durable. Materials of better quality ensure safety, excellent performance, and durability. It’s always a good idea to go for the best cat door for the indoor door, you will save down the line.

Benefits of Installing a Cat Door:

Outlined below, are a few benefits of having a cat door installed in your home:

  • Having a cat door gives your cat independence, but make sure you treat him with a good cat flea shampoo or a good flea spray for cats to keep him clean
  • A cat door helps to keep out stray pets from your home while granting your cat free passage
  • With a cat door, you don’t need to be stationed at your door 24/7 to grant your cat entry or exit
