Which Size Cat Door Do I Need?
A cat will need to use a small or medium door. Measure your cat’s width and height. As shown on our measuring guide, the top of the door flap should be at least as high as the top of your cat’s shoulder. One of these two sizes will fit:
Small Cats: 6″ in width by 11″ in height.
Medium Cats: 8″ in width by 15″ in height.
Don’t hesitate to call us if you have any questions. Selecting the right size door will support your pet’s long-term comfort and well-being.
Do I Have Color Choices?
We offer three desirable color options for our cat door window inserts:
White: a perfect match for many home windows.
Satin: a smooth silver, similar to the matte side of aluminum foil.
Bronze: a dark, rich brown hue.
The inserts have a discreet frame design, allowing the maximum area for viewing. A security panel slides smartly over the opening whenever you prefer not to allow pets to go in or out.
Is a Cat Door Window Insert Secure and Will It Keep My Cats Safe?
The short answer to this question is yes, cat door window inserts can be secure, and they can keep your cats safe. Cat door window inserts are designed to provide your cats with access to the outdoors while still maintaining the security of your home. These inserts are typically made from a durable plastic or metal material and are designed to fit securely into the frame of your window. They come with a locking mechanism that prevents unauthorized entry and keeps pets from escaping. Additionally, many cat door window inserts also feature an alarm system that will sound if someone tries to break in. With the right cat door window insert, you can easily protect your cats and keep them safe.
Are There Any Special Considerations When Choosing a Cat Door Window Insert?
Yes, there are several factors to consider when choosing a cat door window insert. Firstly, you need to make sure the insert is the right size for your window and your cat. You also need to consider the weatherproofing of the insert, as well as its security. Make sure the insert is made of durable materials and has an adequate locking system so that your cat can stay safe and secure. You’ll also want to take into account any other features you may need, such as a dual-flap system or a timer for when you want to keep your cat inside for a period of time. Finally, ensure that the insert is simple to install and maintain. With these considerations in mind, you’ll find the perfect cat door window insert for your needs.
What Are the Drawbacks to Using Cat Door Window Inserts?
There are a few drawbacks to using cat door window inserts. Firstly, the cat door window insert will reduce the amount of natural light that enters your house, as it will take up part of the window. Secondly, the insert may not be energy efficient, as the seal may not be as good as a regular window pane. Finally, the cat door window insert may be more costly than just purchasing a regular window with a cat door already installed.

The product arrived and I installed it the same day. Our dogs started using it by the next afternoon. Thank you!
Thank you Pet Door Products for making mine and my families lives so much easier with pets. The convenience of having our families pets let themselves out without us having to let them out constantly has put so much time back into our hands. There has been close to no accidents from our dog since installing our pet door. Our dog can let himself out throughout the day when we are at work, which means not coming home to big potty messes like past times. I would highly recommend getting a pet door product installed in your home for peace of mind, and the for betterment for your pets. Our dog is happier then ever I believe because he has the ability to roam outside and sun bath (his favorite) when he desires and above all to go to the bathroom right when he needs to. Our lives are so much happier and healthier now. I also have to say that from the beginning to the end of our experience with Pet Door Products we were listened to, we were cared for, we were treated with professionalism, patience, kindness and above all more peace within our home since making the choice to have our pet door installed. Thank you for an amazing experience we will highly be recommending all of our friends and families to your company! Top of the line customer service. You guys are the best there is!!!
We love, love, love our dog door. Our dogs picked up on it right away. It has been so nice to allow them to go in and out without having to get up all the time to let them out. I also like how we can close it down when we have people working in the yard, etc. and don’t want the dogs to go out. Service was great and the installers were professional, skillful and did an amazing job installing not one but two doors for us. I can’t say enough good things about this company and the people that helped us. I highly recommend Pet Door Products and their dog door!
Most people won’t see the original review, which is just fine. This one is far more important. I believe how someone responds to a mistake says far more about them than just day to day transactions do. In this case, I’m happy to share the story. Some details are irrelevant, but a mistake happened on a Friday afternoon that affected us. I posted a review during the weekend but the replay came Monday morning, and that’s fair, which is one reason I’m adjusting my rating. Pet Door Products were very apologetic and owned the mistake, not once was blame placed where it shouldn’t. They owned it, and then fixed it. Our installation happened later the same day, for which I’m grateful. The result is incredible, with exceptional quality. I don’t need a discount, I don’t need free stuff, I wanted communication and a solution. In the end, I received both in a timely manner and I’m thrilled with the result. Thank you for everything, specifically Alyshae. Would recommend working with this company.
Thank you PATRICK RUNCO for assisting me in the right pet door! Not only would I need the right door for my pet but the correct one for my sliding glass! Thank you.
I purchased a sliding door insert from Home Depot for my dog and hated it because I basically couldn’t use the door for myself. The pet door slider gave me the ability to use the door again and I love it. Friendly service and it was installed earlier than the 6 weeks I was quoted at.
Ordered the door and had it installed within a month! I have a large 160lbs dog who fits fine in their XL dog door. He was timid at first, but has started warming up to the door! No air leakage, not crazy loud, and overall I am glad I invested. It is a bit spendy, but worth it.
i didn't buy a door but i don't think i need to, just look at that thing! it glows in the light when a dog passes through! i would HIGHLY recommend this product. you all should invest in this doggy door and make you pooch happy!
We had them install a doggie door in our sliding glass door and it looks great. The service was amazing. My puppies are unsure about the new door yet the are smart and will figure it out.Thanks for taking care of us
We are so happy with the new pet door in our sliding glass door. Now the kitty can go in and out without a hassle or worry about the utility bills. Gabe and the installers were a pleasure to work with. I highly recommend them!
We love our doggy door. The install was super quick and easy and it’s been a great product so far! Our dog got used to it really fast and loves the freedom she has now.
Best idea ever!! Our pet door is so nice in our sliding glass door. Thank you for the fast efficient service. Pet door products is easy to do business with, they measured, ordered and installed. I was able to train my dog to use the door with holding treats on both sides for a couple days.
Great product. Custom fit to our existing sliding frame. Our pups love the freedom of coming and going as they please.Thank you for the great product.And thank you Gabe for the clean installation.
The quality of the door is fantastic. We are very pleased. Gabe even called to check how things were going and gave me some great tips to help my dog acclimate to the door.
Gabe was nice to work with, and our new dog door looks great. We love that it's a full secure sliding door as opposed to an attachment. Excited to get our dog used to using it. 😄
Great product! Having the doggy door has been great for our 10 month old dog. They were very responsive and always texted me back on checking the status of the door. Gabe called me to make sure I was satisfied with the install and making sure that our dog was getting used to it!
We love everything about our new pet door! Because the door was installed in our existing sliding glass–it saved us cost on having to expand our deck (and the headache of cutting a hole in our home!). From contact to quote to install–the guys at Pet Door Products were awesome. I’m convinced that everyone with sliding glass needs this dog door 👍🏼
We originally bought a patio pet dog door insert from Home Depot when we moved into our new home a few months ago. It leaked, let in bugs and was awful. Our window company recommended Pet Door Products and was put in touch with Gabriel. Gabriel came out when scheduled and gave us an estimate on a pet door that same day. With current supply chain issues he was upfront that it would take 6-8 weeks to come in and they would come out and install when they received it. We've had it for about a month and it is worth every penny! No more leaking air and bugs getting in and the door works the original way it was intended. We opted for the larger insert just in case we ever get a bigger dog and our Boston terriers have no problem going in and out. I would highly recommend. It takes a lot for me to write a review but this door is definitely worth it.
Gabe was awesome and so were the installers. Professional, courteous and the product is great quality, glass, insert and all. The installers were even so kind as to try and fix the latch on my door that has been having issues staying locked. Above and beyond!
The product and service for this company were amazing. We had a pet door insert previously and it really hurt your confidence trying to squeeze out the back door. Our new dog door is large enough for our golden doodle and all the humans can fit out the sliding door without having to turn sideways.
My daughter referred me to Pet Door after having one installed. Gabe was very helpful and helped me decide which door would work best for my situation. I ended up buying a wall mounted door, installed it last Saturday (I live in Southern Utah) and it was one of the best decisions. We have high winds in this area and the flap is durable and stays shut with the magnet. It even took my dogs a little bit to get used to actually pushing the door open instead of just breezing through it like the old dog door. Thanks Gabe!
Gabe was very efficient and booked me for a free bid very quickly! Just got my door put in last week and i love it!! Can’t say enough good things about this place.
We love our doggie door, the Salesman Gabe was very informative and kept us up to date on installation time!He also followed up afterwards on any installation issue.We definitely recommend Pet Door for your next doggie door!
They were prompt, friendly, and professional. Most important, we love the dog door! The dogs learned to use it quickly, and it does a great job of keeping out the wind and weather!
Our retro-fit sliding glass door with a dog door has been the solution for a long standing problem. We have four dogs ranging from 16 to 80 pounds that constantly want in and out of our backyard. Now they have the freedom to come and go as they need and want. The dog door has already shown its ability to stay closed during a storm. Yes, there is thermal loss. But we can mitigate that
Great product! This thing has allowed me to sleep again. My dog was constantly waking me up to let her out in the middle of the night. I was reluctant to get a doggy door because I hated how all the inserts for sliding glass doors would take up so much room in the doorway. With pet door products I get the doggy door and full walking space. In addition the sales rep Gabe was great to work with and install was quick.
Fast install, high quality product. We had a dog door put into our sliding glass door. Very happy with the outcome. Dave was quick to respond to questions that popped up.
Great product and great customer service! They came out and did all the measurements for us, the installation was handled by them and super seamless and our dogs are loving the new dog door! Would highly recommend.
AJ and Alysha were great! The assistance with the measuring process as well as installation was spot on. Great product, pricing and great service!Thank you again!
They were good to work with.The door looks great and works awesome.My dog loves being able to come and go.Even better I don't need to getnup and let him out every 3 minutes. 😆
Had a pet door installed in my sliding patio door today. Finally my St Bernard and I can both use the patio door. New install but looking at the quality I have no doubt it will last. Holds up to winds as well, something my old pet door couldn’t do very well. The customer service was great as they kept in contact with me and the glass installer since I ordered.
Pet Door Products really went the extra mile to make sure I was happy and taken care of. The customer service really made the experience. The products are great too. My pups couldn’t be more happy with their new entrance. It looks great! I would recommend using Pet Door Products.
We LOVE our pet door! And the process was so good. The salesman who visited us was very pleasant and professional, and the installation went smoothly. It looks great!Ruby the Beagle would still PREFER that we open the door for her if we're standing there, but goes in and out with no problemWe highly recommend PetDoors!
Gabe was very professional! Pricing was good and customer service was more than I could ask for! I have already recommended Gabe to several friends! It is nice to get some good service for a change with the whole world being as messed up as it is!Thanks Again Gabe! We need more people in this World like you!
Absolutely 💯 would reccomend. The installation was quick and the installers were very professional. Our dogs loves it! We would hands down reccomended springing the extra money to continue to have use of the sliding door. My grandparents bought a dog door inset and they do not have the accessibility we do.If your dog loves to be outside it is worthwhile to call and talk with them about your next steps
Wonderful customer service! They came out measured were very professional. Give us an install window met the deadline. Our dogs love it! They fit through the door and the door keeps the outside elements outside. Highly recommend.
We love our new dog door! I chose this company because of their great reviews, and they sure do live up to them. Great service from the salesman Brock to the installer.He was quick and very professional and friendly! Love this company!
We have 3 big dogs and had been looking for a dog door for awhile. We called Pet Door Products and they sent Gabe out within a few days to measure our door. Our dogs love being able to go out when they want. We should have bought one from them a long time ago. Everyone was very nice and helpful! Would definitely recommend them if you are looking for a dog door.
I called to ask for a quote and they sent a representative out to our house, he was very professional. My family has a unique situation at home and they worked with us in order to get the door installed... Everything on the worked great, it is solid and it let's no cold air in. It took a min for the animals to get used to it but now they use it all day, everyday!!!!
We love our new pet door! It’s actually our second one with Pet Door Products, since we moved, and we couldn’t be happier with the service and the product!
VERY happy with the new pet door! Installation was very quick (<30 min?). They pulled the old door out, took it out front to work on it, then brought it with new door in and put it back on the track. Awesome solution to needing a pet door in a sliding glass door.
Having a pet door is a true game changer. This one is expensive, but it seems to be pretty high quality. Looks good in our sliding door. Our experience working with the company was good. The installers were fast and good.
This was the perfect solution we were looking for. We didn’t want a hole in the wall and the insert we previously had didn’t allow the door to open very much. We’ve had it for a few weeks and are happy with it so far!
Gabe was professional and fast in getting everything processed. Once the door was ready the team was fast and courteous with getting it installed. The door is fabulous! Great quality! Well worth the price.
Very pleased with my experience with Pet Door Products. Brock was knowledgeable of the products and helped me figure out the best application for my home and pets.
I’ve been having problems trying to figure out what pet door to get and how they work. I was able to talk with one of your salesmen Brock and not only did he have answers all my questions but with his kindness and knowledge helped me with the measuring process as well! Great company and great employees !
We have three doodles, one very large one fat and one medium small. They learned quickly how to use the door. Coolest part is the ability to add and take away magnets for strength of hold, we have 60+mph gusts regularly and the dog door holds strong without fail. Built well and installed in the promised timeline, no complaints as it’s made our life easier.
10 out of 10! This was a pretty easy and seamless process from start to finish. I recommend this company to all of my animal loving friends and family! Use these guys!! Thanks again!
My experience with the agent and customer representatives from Pet Door products was awesome. They helped answer questions and concerns that I had and helped me feel great about installing one of their doors at my house. My dog has gotten used to using it and it has been extremely convenient for me! These guys are great, go to them if you’re looking to get a dog/pet door!
I’m so glad we found Pet Door Products. I’m just sad we didn’t find it sooner. The new door has been amazing. Our dog has the freedom to come in and out and we can still use the whole door to go in and out as well. But we can also lock the dog door if needed.We get crazy winds and the wind hasn’t budged the dog door once.Our installer was amazing as well. He was so quick and he even fixed the lock on our sliding glass door that has never worked!
They are amazing to work with and so quick! They communicated with me throughout the whole process amd the order only took a few weeks to complete and install.
We had a great experience with Pet Door Products. They came to give us a quote quickly and were within the time frame of delivery for the door. Install was quick and simple and they did all the work including a cleaning at the end. It has been amazing for our dogs and we can’t imagine going back!
I love my dog door. It is by far money well spent, not to mention the great customer service I received from my salesman to the installation. Thank you!
