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.

My name is Ben Roberts, and I absolutely love animals. So, naturally, I love writing about them too! As far as my animals, I have a Pit-bull, a Beagle-lab mix, a Chihuahua, and one old cat. Each one of them provides me with a new adventure every day. And the best part is they’re all best friends. Well, except the cat when he gets a little annoyed.

My cats are indoor cats but I think they’d like the interior door since sometimes they want to escape from each other.
Those flaps and doors are so great and cats can be so smart. I wonder if it takes a lot of training for the average cat to learn to come and go through these great routes.
I’ll never forget when we were teaching our cat how to use the door. It took a bit, but he learned and loved it. He was an outside farm cat but we wanted a place for him to go for safety and warmth. One day he decided to come in and show us his “catch” of the day. It was still alive. LOL
Great advice for all the cat people! I recently saw a tent/tube attached to a cat flap so that the cat could go outside but then not run away. Pretty cool stuff for kitties!!
My cats would want one. They are so interested in being outside, but I worry, so they only get to sit in a window.
These sound like some great recommendations – there is so much to think about when it comes to getting your home fitted with a catflap.
Our cat was an indoor-only cat. However, I can see how this could be really handy for cats who are allowed to go outside. The interior kitty pass is really cute.
We have a cat flap on our basement door. It’s a life saver when my dog goes after our cat! He zips right through it to safety. =)
I would love to have a flap for my dogs and it would be such a time saver
Wow this was very useful mini doors for my pet cats. Specially when they wanted to go outside and play. I’d love to have this at our house.
What a useful resource for cat owners! I’m sure it’s so important to find a high quality cat flap that’s not too expensive.
we’ve never had a cat flap with all the cats we’ve owned. now I feel like I have deprived them!
I thought about getting one of these for my cats. They love to go outdoors. I’m just always worried about other critters getting in because we live out in the country.
These are so great for any cat to come and go as they please. I think any cat would love these, especially if it’s on a bathroom door. You know how cats are. LOL
Cats are a lot more clingy than some people give them credit for. I think indoor cats would really love to be able to use these to stay with their people.
I always wanted to know more about cat flaps. Thanks for sharing these info!
I think one of these will be perfect for my aunt for her cat!
Didn’t know about cat flaps. But these are really so unique and fascinating and this is a nice list of recommendations too.
I would love to get a cat flap! I need one for my catio.
What a great idea, like doggie doors. My cats are 100% indoor, so they don’t use them, but I know so many friends that have to let their cats out and this would eliminate that need to keep doing that.
This is really beneficial for fur parents and for the cats, too! I would love to have one if only I could have my own cat.
Such a great post!I had no idea about the cat flaps until this post! So thank you for sharing info with us plus giving us multiple cat flap door options 🙂
What a great idea! No cats here but two pups. I really want to install something similar for them.
I’ve always wanted a pet door but most of the places I have lived don’t have fenced in yards. But if I was able to, I certainly would because it would make it easier for my pups to go outside when they need to potty.
Perfect post and I’m sharing it with my neighbors who are moving into a new home. They have cats and we were just talked about cat flaps. Great recommendations.
