The Ideal "Cat Sash" for Sash Windows

You want your cat to come and go freely, whether that’s through the door, or through the window. No more waiting with the window open for your cat to come back inside. The Cat Sash window is available in two sizes including the Hefty Cat version, which is large enough for very big cats or small dogs. They both incorporate a '4-way' locking mechanism, which means that the pet door can be set for in only, out only, both ways or completely locked.

A strong point for these sash window pet doors is that the flaps are made from Lexan--generic name polycarbonate--which is very strong. The weak point in this flap design is the "posts" that the flap swings on at the top. The Ideal Polycarbonate "posts" are much harder to break. Along those same lines, it is wise to ensure that the top of the pets shoulder is no higher than the top of the flap opening. This prevents the pet pressing against these "posts."

Another nifty feature is that, because a separate locking cover is not required, you can choose to have the factory mount the flap to the left, right or centered when inside looking out although the left and right positions are additional cost and made the order "custom non-returnable."

PLEASE NOTE: This product ships directly from the manufacturer and may take 1-3 business days before it actually ships.

Customer Reviews

  • Andy loves it. and so does his momashirley
    How do you rate this product?

    Very easy to install and easy for my cat to learn to use. But, the door wouldn't close all the way to when he went in and out. So as it got colder out side, I had to contact you and you had me contact the manufactor. He was very helpful and sent us a new door with a much stronger magnet on it and now it closes when Andy goes out to play and potty and comes in to eat and sleep. Thanks, Momashirley & Andy

  • One of our best investments
    How do you rate this product?

    This is our second cat sash. We are in the military and move frequently. The cat sash window allows our cat to come and go as she pleases regardless of where we are. We decided to keep the old cat window at our cabin and we ordered another one that moves with us to where ever the Army sends us. This product allows our cat to be independent. The different lock choices are a plus. We have had the original product for over 6 years now. We have had to get a bit creative with the insulation in the window sill but once that was figured out, there are no worries. I would recommend this product to anyone who is contemplating adding a cat door/window.

  • Fabulous Product!!
    How do you rate this product?

    We purchased the Hefty Cat model because one of our cats weighs 18.5 pounds - he's big-boned, ha ha! He fits through it just fine, although he is a little embarrassed that the delivery person now knows he is a little chubby. It was easy to install and we are very pleased with the quality of construction! We also like that there are different lock settings for the door, as we do NOT want the cats to go in the back yard when my daughter's German Shepherd is out there - that would be VERY bad!!!

    Wonderful product, and I highly recommend!!

  • Cat loves it; I like it
    How do you rate this product?

    We purchased the larger of two sizes for cats. The door is quiet in operation and our cat took to it immediately. He had used a flexible cat door in the prior house, and just walked through this one -- no retraining required.
    We ordered with door on the left, but this does not mean flush with the left side. Expansion areas are on both sides of the window, so "left" or "right" is not flush with edge. This is okay, but the left edge position is what I had expected.
    My reservation is that the flap lock doesn't seem that strong. We have raccoons in the yard at night and I'm concerned that one might pry the cat door open some night. A more secure lock, or provision for a metal cover would be a nice feature for any future design.
    Overall, the door meets our needs, has a clean look, is quiet and was a good value for the price.

  • Easy to install, well made, cats like it.
    How do you rate this product?

    The cat door was as advertised, improvement over my homemade unit. Easy to install, well manufactured and, most importantly, the cats liked it!

    How do you rate this product?

    The door was not as far left as I thought it would be. The PIN provided for Security was a Joke. I installed Metal Rods between the window top and Frame. The Insulating tape & vinyl strip is also a joke. A real rubber insulate strip should be provided to mold between the product and window bottom, and product and window frame. For the price of the priduct, these could have been provided.
    I ordered another product that came damaged. Moore Pet lied to me about calling UPS for pickup and telling me some further lie about maybe taking 2 MORE weeks to get pickup and reimbursement. I would NEVER order from MOORE PET AGAIN.

  • Change my life
    How do you rate this product?

    My only regret are the years I spent getting up multiple times a night because the &*%$#! cats were pestering me to come in or go out. Finally got this because we're going to have a baby soon and THAT will be waking me up continually, I imagine. Both cats took to it in less than a week, even the not-so-bright one. It is very easy to install. I didn't use any of the included weather stripping. The main place the wind comes through is not between the window and the sash but right above the cat flap itself, so not sure how one would seal that better without compromising the swing of the door. But we live in Florida so it has not been a concern. I also can't speak to its security features, since we don't care about that, either. But it looks good, is simple, and the cats love it (and so do I).

  • Not really that secure
    How do you rate this product?

    our window is ground level, we couldn't secure the window properly and our house was not secure.
    We asked to return the product but were told it was a custom order and non-returnable, even though the manufacture date on the box was the previous year. We did get a partial refund and customer service was very nice.

  • Very Well Built Window
    How do you rate this product?

    I could not be happier with the purchase of this product. I looked into having one built into the window, which was estimated at $750. The cat door I purchased fit very snugly into the window and locked into place. I recommend purchasing additional insulation and make sure you use the window lock. Otherwise, your cat will be very happy like mine, because she is in and out, in and out! Duffy the Cat

  • Wonderful
    How do you rate this product?

    I have this in my living room window to take the place of the cat door in the basement which is very hard for me to get to. It is the most wonderful thing! It leads out to the "catio", which is secure from coyotes and other animals, and Shadow loves going out there. I even leave it open at night, since he has easy access back into the house if necessary. Worth every penny.

  • wind blows flap, lets in hot/cold air
    How do you rate this product?

    I bought this product 1 yr. ago. It looks very nice and at first I was very pleased with it. Then we had a few very windy days & the magnets that are suppose to keep the flap shut are not strong. At 20 mph the flap was blowing like crazy letting in all the very cold air and rain!!!!! I called and they sent me more magnets but they were useless!!! In winter in the northeast we get very cold winters with heavy winds. Also the the 4 way lock broke off and they sent another. Very difficult to replace it. We threw this in the trash!!! We are looking for another cat windoor.

  • Outstanding Product
    How do you rate this product?

    Superb quality, extremely sturdy, ridiculously easy to install, air-tight, attractive. I trained my cats to use it using treats; only took a few days; they love it. Attached a board as a ledge on the outside of the window; works like a charm. Couldn't be happier with this cat door.

  • Great invention
    How do you rate this product?

    We have a new "catio" behind our house. The former cat door (from when Shadow was an outdoor cat) is in the basement and I am no longer able to get down to open and close it. This "cat sash" installed easily into a living room window and gives Shadow a way to get out without any one having to help him, and it makes it possible for me to have the central air conditioner running. In fact, the AC unit is right outside the window and is a good staging space for Shadow to come and go. The quality is excellent! I thought the price was high when I ordered it, but now that it is here and in use I think it is worth every penny!

  • great product
    How do you rate this product?

    This is wonderful and was easy to put in I installed it in a few min and it looks great. My 3 cats took a few days to master it but I just held a container of catnip on the other side and they figured it out fast. All the years of leaving a window open etc for them to go out on back porch to cat box and food bowls are in the past now. So we are very happy w this door and keeping the ac inside.

  • Great product
    How do you rate this product?

    I had to buy some extra weather stripping, but the window was easy to install and works great. It only took me a few days to teach my cat how to use it, and now he goes in and out like a pro! The window opens to a catio that I built for him using a completely enclosed dog kennel. My cat can go outside anytime he wants now and be safe. He particularly enjoys the kennel when I am outside in the yard with the dogs because he can join us. I may have to remove the window in the winter if there is too much of a draft.

    Overall I am very pleased with this purchase and would recommend it, and so would my cat! He was a stray cat that I found in the neighborhood and had been living outside for a long time. After I took him in he was desperate to go out again, and I felt terrible having to constantly turn him away from the door. The window and kennel now let him enjoy the outdoors in such a safe way which makes me so happy for him.

  • First rate product
    How do you rate this product?

    Our two cats use it multiple times each day.

  • Absolutely Purrfect!
    How do you rate this product?

    Bought the chubby cat window and it fits perfectly, little to no adjustment required (did purchase the widest one for my window). Only issue was the unit did not arrive the first time due to winter weather or what, but company backed their service 100% and got another one out to me promptly! Once the cats get used to a cat door in a window they will not need me for anything other than food, water, and cat pan cleaning. My life is going to be more now than "let me out, let me in, let me out, let me in". Great great idea and great company to work with!

  • Great! Great! Great!
    How do you rate this product?

    So glad I found this pet door. I'm remodeling my house and had to do away with the pet door that was installed in my sliding glass door. Came across the cat sash and my cats just love it as do I. Thanks for a great product.

    How do you rate this product?

    This is a wonderful way for my kitty to have access to indoors & outdoors. The construction is very nice and it installed into the window sill with a snap. I am so pleased with your products. My first cat door was the panel that fit into a sliding glass door years ago with the four-way locking and magnets. That too was a tremendous problem solver with neighborhood cats attacking my kitty. She could run in & be safe...and no more vet bills.

  • Nice Sturdy Well Built Cat Door
    How do you rate this product?

    This cat door is well built and heavier duty than my existing windows. I am very pleased with the quality. I probably should have ordered the door that was mounted to the left side, but with the center mounted window I added a shelf on both sides (in and out) for my cat to go out on and it worked great. She became a pro at using it within the first day and because she is an indoor cat this door allowed us to relocate the litter box on the lanai where she spends most of her day.

  • very poor quality
    How do you rate this product?

    The product barely fit into the window and once installed , the air leaks were multiple-. I would not use this product again-We were very disappointed. The quality of this product was very low and the materials used were cheap and ill fitting-very unhappy with this product-would NOT recommend

  • still searching
    How do you rate this product?

    It is not a green design because air just comes through multiple areas of this Cat Door for Sash Windows product, allowing both cold and hot air to disrupt the temp you have set for your indoor living area. This is a significant design oversight in my opinion makes this product worthless, therefore I am still searching for a functional option to let my kitties out without having to open and close the door for them.

  • Bigger door is better
    How do you rate this product?

    We originally ordered the smaller cat door and had to return because it was too small for our 12-pound cat to go through. He loves it now and uses it almost exclusively. He also had it figured out in a day or two.

    There are only two items that I have issues with. 1st, there was not enough weather stripping in the packaging of both doors I ordered. I had to go to home depot to get enough of the weather stripping. 2nd, the lock on the door is not high enough to stop a determined cat from going in/out.

    Altogether, I am very pleased with the cat door and am glad I purchased it

  • excellent product
    How do you rate this product?

    if you are thinking about buying a cat door for your indoor/outdoor cat, do not hesitate to buy this product. I have raved about it since I bought it. I had a glass door so I could not figure out how to have a cat door...this solved all my problems I had my handyman put it in, but it took only minutes. It has a good seal, I do not feel that I am letting in a lot of hot/cold air. The best part is that my cats learned how to use it within a week and I never have to worry if a storm comes while I am gone. They can come and go as they please-and they think they are so smart! The only con is that the lever to lock the door is very tight and hard to turn. Overall, I wonder why I did not buy this sooner!

  • Looks great, great service, locking mechansim weak
    How do you rate this product?

    I installed the "cat sash" door for my window over a year ago. To make it easier to get in and out, my husband built a shelf on the outside so the cats could come back in easier (we already had a sill on the inside). I had originally ordered the wrong size and had no problems getting it returned and the correct size shipped.
    One of my more aggressive cats didn't like being locked out and banged so hard on the door part that he broke the plastic lock--now the door will still keeps cats locked in, but not locked out unless I remove the outdoor shelf. The cats also managed to pull off the insulation around the flap so it lets in a little cold air but it's easily fixed..
    All-in-all, I like this door (looks like the flap and lock part may be replaceable). and its much better than those magnetic ones (which my smarter cats could open even if locked and without a magnet.

  • Door doesn't close properly
    How do you rate this product?

    I bought this Ideal cat door for a sash window about eight months ago. It came on time, there were no billing problems, and it installed relatively easy, but I would recommend against buying it. When the door swings shut, it doesn't line up right at the bottom. It leaves a big gap for the outside air to come in and for my air conditioning to exit.
