What Does Cat Flap Mean?

Cat flaps are small openings that allow cats to enter or exit a home by themselves.

In other words, they’re cat doors…just, well, flappier! 

In their oldest designs, these flaps were simple holes without much technology intervention.

But cat flaps have evolved into rather complex constructions with some ingenious design features. 

For instance, you’ll find most modern cat flaps are flexible flaps or commonly hinged, spring-loaded panels.

Some options are even electronically controlled for even more convenience.

Benefits of Fitting a Pet Flap

Let me be clear upfront- it’s always better to keep your kitty as an indoor cat vs. an outdoor one.

That said, if you just can’t swing it, then there are several fantastic benefits come from having a cat flap inside your home.

Benefits for Your Cat

  • Less likely to suffer from separation anxiety, since they know they can always get to you.
  • Your cat can escape danger from indoors (intruder, another pet, fire, etc.)
  • Your cat can escape a danger outside your home (lousy weather, wildfires, another animal, etc.)
  • Lower chance of urinary tract infection from “holding it” while waiting for you to let him out.

How Having a Pet Flap Improves Your Life

  • Your doors and walls will have a lot fewer scratches on them
  • No longer need to open doors for your cat
  • Could mean the end of having litter boxes

How Much Does it Cost to Fit a Cat Flap?

Cat flaps will vary greatly when it comes to their price depending on several factors: brand, size, design, technology, and overall quality. 

A standard two-way pet door can cost as little as $10 for basic models.

But more advanced designs like a microchip-detecting option can get as high as $150.

You then have to account for the installation costs.

Most professionals will charge either a per-project fee or an hourly fee, but the expected total will usually fall between $125 and $300.

If they provide the flap, it will cost more.

What Size Pet Flap Do I Need?

Cat owners should never buy a pet flap without measuring their feline.

If you do, the door might end up being too small or big for them, making this purchase a waste of money. How do you prevent this outcome?

The simple answer is measuring your cat. It’s the only way to make sure you obtain the right size door for them.

This process starts by taking measurements from their feet to shoulders.

You should also try to account for other factors, such as distance between the cat’s under-belly to their head and overall width before choosing an option.

Once you’ve got these measurements, use them to construct a cardboard cutout.

This cutout will help you visually determine whether the sizing will work for your cat.

I’d recommend keeping the opening’s width two-inches wider than your cat’s widest part, as well.

This same two-inch cushion should be applied to the cat’s height.

These cushions will ensure your cat doesn’t get stuck when your measurements are incorrect.

Plus, a bigger pet door helps coup with your cat get larger as they grow. 

Where Can I Install a Pet Flap And How?

Pet flaps or cat doors can be placed in porch doors, door screens, walls, doors, or any other location with access to the ground.

If you’re wondering “Can a cat flap be installed into my glass panel?” the answer is yes, but you’ll almost definitely need to hire a professional cat flap fitter.

If you’re planning to go the DIY route, you must understand the thickness in which it can be installed before installing it.

If this aspect seems a bit too complex, you can always buy a tunnel telescoping pet door.

These options are capable of being installed on varied thickness with relative ease. 

Cat flaps for windows are meant to be installed on window screens with lower elevations.

This situation will ensure your cat has easy access to enter and exit as they wish.

You can apply the same for cat flaps for sliding windows, as well. 

The install process begins will cutting out a section from your door, window screen, or wall before fitting the cat door inside it.

Most of these models with a cut-out template to ensure you know the right amount to cut.

Once you made this cutout section, the cat flap can be fitted inside using fasteners.
