  • And we did it! We have a catio!
Size: 7-1/2" x 10-1/2" Chubby Kat Flap Size Style: Window Width: 33" - 38"
2020 UPDATE: We still have this insert and it is a permanent fixture of our window. We now have a full screened in patio (with the pet/trampoline screen) for the cats to go in and out of and we also added two cats. Highly recommend this. We also added a door insert in our sliding door that goes out to the patio, but we have left this in so that the cats have multiple ways to get in and out of the patio in case one fails or just to keep the peace between them. Wow, what a project it was installing this window sash cat door! But already it is worth it, and the cats love it. We used ours to put in our bedroom window which leads to a small "catio" that we built outside. We did not want to have to create any big holes in our doors or walls, so this Ideal Pets Sash - Chubby Kat is perfect. Our cats are not fat, but they are tall, so we wanted to make it comfortable for them to get in and out of their catio. They learned very quickly how to use the cat door (same day) and did not want to leave their catio until we finally made them come in at 1 a.m. We live in Florida, and it is so hot right now that we cannot supervise our cats in the back yard as often as we normally would - we have to wait for it to cool down. So this cat flap gives them the freedom to go outside and inside as they please, and it still keeps them safe from traffic and other potential dangers outside. Anyway, back to the PROJECT of getting this installed. It took a lot of tweaking to finally get this to fit the way we wanted, especially to be able to make it as weatherproof as possible. Our window is about 35 inches wide. This window sash has springs on each side so that you can push the sides in to get the sash into your window frame, and then when you let it go they stretch back out and are tight in your window. The small silver knobs are basically just used to tighten that mechanism so that once the window sash is in place, you secure them and they will no longer be able to be moved. This sounds very simple, and for the most part, it was, but I am here to explain just a couple of things we had to do to get ours to work. Although the sash fits width wise into the window frame and weather stripping is provided, we ended up using about 7 feet of our own weather stripping to secure this thing. It comes with black weather stripping, which would have looked terrible all around the window and sash. We had to line the bottom of our window, the bottom of the window frame (tracking), both sides of the sash, in between any holes that were exposed between the window and top of sash. Also, we had to weather strip the sash itself from left to right all along the front below the cat door flap and silver knobs, as well as much more behind the sash to fill in any spaces created near the bottom window tracking. It takes a little bit of work to get the sides where you want them and to tighten the flexible side mechanisms just right as well as getting the sash at the height you want it. If you take a close look at the item you will see that the plastic cat door in the center has a white plastic frame around it. This will have to sit above your window tracking or else you will create a huge gap, letting air in and out, etc. In short, just be prepared with your own weather stripping (I suggest white colored), and I mean many feet of it, in different widths and also in different thicknesses (yes we had to choose different widths and thicknesses for our weather stripping.) It was a lot of careful and detailed work, but it really only took about 3 hours to complete - and that is definitely worth it for the amazing outcome! We are so happy with how this turned out and our cats are too. A couple of other things to note: despite all the work on the weather proofing, the product itself has a few features that will make it unable to be perfectly fully weatherproofed. As other reviewers mentioned, this is a cat door. The swinging door is surrounded with gray bristles that act as its own little weather strip, but those definitely let some air in and out. I believe the door is magnetic so that it should close behind your cats automatically, but since they have to make that magnet weak enough for a cat to get in and out of the door, it doesn't always fully close. We have only noticed this a couple of times. For the most part. it does close all the way. Above the swinging cat door is also a little bit of space that is not weatherproof. These are just small considerations to be aware of. In all, the small amount of air that may get in and out is probably much less than when you are opening and closing the doors to your house. I hope this information helps. We love this product and our cats do too! If this review helped you please feel free to select "helpful" and/or leave a comment. ... show more

This is a fantastic invention! I didn't want to cut a hole in my beautiful door and was so delighted when I saw this. It works just as described and is well constructed and easy to install even for me (an old person)! Extremely pleased!

  • Great door overall but the lock needs improvement.
Size: 7-1/2" x 10-1/2" Chubby Kat Flap Size Style: Vertical Sash Window Height: 32-1/2" to ...
My cats really enjoy being able to go outside into their catio whenever they want to. This door was easy to install, the instructions were clear, it is easy to remove when I need to vacuum the window well. I have two large breed cats, the oldest is 2 yrs and weighs 15 lbs. The breed average is between 18-25 lbs and they can grow until they are 3-4 yrs old. This door is plenty big and will be large enough when my cats are full grown. I also have a 15 yr old cat weighing in at a whopping 5lbs. She is tiny. This door is easy for her to use as well. I installed the door in the fall. It is in my home office in the basement. The window is pretty tight and doesn't have gaps around the edges. I didn't notice much of a difference in temperature in the room unless I was standing right by the window. The only issue I have is that the lock is easy to move. The 15lb cat is orange, crazy, and smart. He learned how to lock the window and was constantly locking the other cats outside. I had to put a screw into the frame under the lock to prevent him from accidentally (or purposefully...) locking the other cats out. If we are gone for a few days this would be pretty bad. However, I do intend to purchase another one so the cats can get into the catio from the upstairs window as well. ... show more

  • Update: I highly recommend this pet window....
Size: 7-1/2" x 10-1/2" Chubby Kat Flap Size Style: Window Width: 33" - 38"
Update: 3rd time was a charm.. Janice from IDP Customer Service worked with me until my problem was resolved. She was very helpful and made sure the issues were fixed. I absolutely love this pet window not that everything is working for my cat. Thank you Janice 😊 Update: This is the second Ideal Pet Products Aluminum Sash Window Pet Door, Adjustable to Fit Window Widths from 33" to 38", Chubby Kat 7-1/2” x 10-1/2” Flap Size THE ONLY ISSUE I HAVE WITH THIS PRODUCT IS THE FLAP! FIX THE PROBLEM, IDEAL PET PRODUCTS!!!!! I did get a replacement, hoping that the flap would close like it was intended to do but it didn't! I love the pet window idea but IDEAL PET PRODUCTS you need to do something to make this problem right. I don't think that keeping on replacing the product is going to help because there's to many people complaining about it. As far as the draft around the window all that's been taken care of with a little weather stripping. At night I actually put cling wrap over the flap to keep the air out and the cat in. 1) No cover closure! My cat has figured out how to unlock it because the locking mechanism is cheap plastic. 2) The flap does not close back on its own, which is not good on the electric bill especially when it's 30° outside. 3) Pretty expensive for something that doesn't work for what it was intended for. 4) The window flap does not get better with time and use or a new replacement, it only gets worse. This is a replacement because the first one that I got the window would not close on its own and this one is doing the same thing. The video and first 3 pictures were taken of the replacement cat window and the other pictures were taken of the orginal. Unfortunately I can only send one video. I have several videos of the other window where it wouldn't close, it was worse thanwhat the replacementis doing. I have tried everything to make sure that it close properly. The pet window is level in all directions so that's not the problem. The problem is the flap, the rest of the window is great. My cat loves the freedom of coming and going but she doesn't pay my electric bill! Would I recommend this window, not really and it's only because of the flap not closing on its own and the locking system is cheap. I've put a lot of time and money in this window so my cat can enjoy the outside the way she was used to before we adopted her. If the company has some suggestions on how to fix these issues than I'm listening!?! ... show more

  • Be sure to get your measurement right.
Size: 7-1/2" x 10-1/2" Chubby Kat Flap Size Style: Window Width: 23" - 28"
Unfortunately, this didn't fit my window, because I measured the wrong dimensions. So I wanted to give you some advice on measurements. First, the product measures a minimum of exactly 23 inches wide when compressed. And it measures exactly 28 and 1/4 inches wide (28.25 inches) when fully expanded. I actually measured this myself. This means that you should measure the narrowest opening of your window (usually the window frame itself) and make sure it's at LEAST 23 inches wide so the product can fit in. Once inside, it will expand to fit snugly against the inside track. The inside track is usually an inch or so recessed into the frame on each side. So that's the second measurement you want to make. The inside track width should be at MOST 28 inches wide. I made the mistake of measuring just the inside track of my window. It was exactly 23 inches wide. I thought this was what I should have been measuring. But the window frame bordering the inside of my window measures just 21 inches wide. And so the product was too big to fit in my window. I had to return it. This measurement stuff may seem obvious to you, but there's actually a youtube video showing someone measuring just inside track for a similar pet door product. And so that's what thought I had to do. It messed me up. As for the product itself, I am giving it 5 stars based only on what I've seen and felt. Keep in mind that I've not actually used it. The quality is better than what I had imagined. The metal parts are fairly thick. I think it has two glass panels, rather than cheap, see-through plastic ones. The functioning of the door itself is fine. It returns to center and doesn't get stuck open. There's also the 4-way locking mechanism on it. And the door itself is made of a hard plastic which actually looks good. It looks like the door seals tightly, and so I don't expect this product to leak much air. It comes with weather stripping and a draft seal. The draft seal should help to eliminate bugs as well. And it also comes with screws you can use to drill into your window frame so that you can lock the window to prevent burglaries. There are only a minor number of negative things I've noticed about it, and they're nothing to worry about. First, the metal parts are pointy and sharp at the corners, so watch how you handle them. Second, the dog door is made of a see-through hard plastic. I've not even used this door yet, but it's already showing tiny scratches on it. I believe that over time the door will turn cloudy due to scratching and constant use. But the door itself is pretty small, so it won't become too much of an eyesore. And every dog door I've ever seen has the same issue. Third, the white paint on the metal looks like it will scratch easily, but you can always repaint it. Also, about preventing burglaries... If you look online, there are a number of easy to use methods for locking windows that don't involve drilling a screw hole into your window frame. One of the ways I've seen is to buy a small diameter dowel rod. You just cut it and stand it up vertically on top of the lower window. The dowel rod will prevent the lower window from sliding upwards, if anyone tries to open it. A burglar would need pretty long arms to be able to reach in and grab the dowel rod. As for the cost of this product, I think relatively speaking it's a good price. I did a lot of shopping before buying this product. There are a lot of similar products out there selling in the $300 range. It's certainly a lot cheaper than those. But judging just by the materials and the simplicity of the product's design, I'd say it looks like it could be made for under $30. The fact that it costs $115-$130 is kind of surprising. And for the frugal minded amongst you, I wanted to tip you off that there actually are do-it-yourself guides on the web which detail how to make these products yourself. That has the benefit of letting you buy any type of pet door on the market and just making your own custom frame around it. There are perhaps better, more energy efficient or more weather proof pet doors to be had out there. You could even design your own door (in addition to the frame). It's all possible. But it requires time, effort, and the proper tools. Which is why I decided not to bother with making my own. Though, now I may have to, since nothing out there fits my window. Hope that helps. ... show more

  • Great Product!
Size: 6-1/4" x 6-1/4" Cat Flap Size Style: Window Width: 27" - 32"
This "cat flap" (as I call it) works very well. Our cat was waking us up every night when he wanted to go outside. Now he can simply come and go as he pleases. I put a chair by the inside of the window with a towel on it so that his feet get wiped as he comes in. Outside I have a plastic step to give him easy access to the raised window. The "flap" itself is pretty solid and does take some pressure to open. My cat prefers to put a foot through first, and then his face. I've had one before with a softer opening (in a different location) but it only took a minute to get my cat reacquainted with using this one. This will accommodate a larger cat. Mine is a tall, fairly lean and long 15 lb cat who gets up to 17 lbs at times. This cat door also allows us to leave for a few days without having someone care for the cat. He comes and goes freely, and has access to his food and water. I do have stray cats in the area, but my higher privacy fence seems to keep them out of the little gated area behind my condo. However, it is always possible for another animal to figure out how to use the cat door if they see my cat using it. So far, so good. My cat also defends his territory so we should be fine. The installation literally takes minutes to do. Just make sure you get the correct size for your window. Once installed, you will no longer be able to open and close that window freely. Also, you'll want to place a small stick of wood in along the side of the window above the pet sash for security reasons, so that a person cannot just push the window up from the outside to break in. I hope you buy this product if you have an indoor/outdoor cat or small dog. It will save you a lot of time and interrupted sleep without having to constantly cater to your pet, and allows you more freedom to be gone for a day or two if need be. Your pet will also be much more content knowing they can freely come and go. ... show more

  • You need to be handy to get this to work
Size: 6-1/4" x 6-1/4" Cat Flap Size Style: Window Width: 33" - 38"
This is not a cheap product and you need to be handy to get it to work right but the components are solid and the design is very nice. Shipping was fast and well packaged. The pet door itself is obviously a cheap one from a third party that you can get at any home supply store. They build it into a custom housing, which is the clever part. I had to disassemble and reassemble the pet door itself because the lock was stuck and the door wouldn't open correctly. That was a bummer. A big phillips head screwdriver was necessary. The cat can use it fine after doing that and he picked up on it instantly even after never having a pet door before. The pet door allows you to lock the whole door or choose in only or out only so that's cool. Installation of the whole unit was super easy. The part that the manufacturer designed is quite clever and really well executed. I think it will last a long time and everything in that regard worked really really well. If that's all you care about then it'll go in in about 2 minutes. The pet door itself will always allow bugs and A/C to escape because there is a 1/8" gap all around it. I think they should include a better pet door to improve their product because the body itself is just so great. There's just no way the manufacturer could plan for everyone's windows, but they should probably include more weather stripping. They do include some instructions and components for sealing the outside of the unit body around the interior window edges from the outside elements, but you will want to go much farther with this if you want to keep bugs/noise/weather out. I would suggest going to the hardware store before you install the unit and picking up an additional roll or two of the soft foam weather stripping and plan on running it on top and possibly on the sides of the unit and anywhere else around your window that you deem necessary. I used an extra 12 feet or so myself because even though I have brand new fancy e-coated double-pane windows and the unit fit perfectly, there would have been plenty of open gaps for my A/C to escape in all sorts of places. I also basically laid down an obstacle course for bugs to hit on their way in and I've caught quite a few in the past two weeks. My window sill looks like a war zone. ... show more
