PetSafe Extreme Weather Plastic Pet Door, Medium | Insulated 3-Flap System Rated -10 to 100F, Paintable Plastic Frame, DIY Install in Doors 1 5/8-2 1/4in Thick.

Great quality and keeps out weather. We use this for our cats and they love it. It took a few times of us pushing them through it but it worked great after a week or so. The quality is very nice and seems sturdy. The flaps are a little heavy for a cat but they manage to push through. It is great at keeping out harsh weather (our area snows and gets extremely hot). I’ve put my hand near it to see if I can feel the heat or coldness and nothing. It is kind of noisy if you animal runs through it but it’s not obnoxious. I really like this product

Easy to install with the right tools! I have a 15lb cat that fits in the small. It takes time getting used to it for the cats bc it is a little clunky when opening due to the magnet closures

Our Dogs love this and it keeps the cold out. We have Miniature schnauzer. Perfect Size!

I finally got around to replacing our dog/pet door after having a classic medium, single flap door for 15 plus years. The flap was tired, twisted and needed replacing. It was like having a literal hole in the wall, cold air pouring in during winter and hot air in the summer. Add wind to the equation and things get even worse. So let’s just replace the door, completely! This thing, at least for me was not a piece of cake to install because it does not fit the existing opening of my medium classic door, it’s larger! This means there is some cutting to do, two sides and the top. A real pain because it required removing the door from the frame, laying out the hole, keeping it centered, then the whole cutting thing. Not an easy task when you’re working with a hollow core, steel door. Assembling was a pain too. I didn’t like the supplied plastic screws and replaced them with 2-1/2” stainless screws making them easier to install but plan on another set of hands to install them. I cut them flush after the installation. The inside frame was a pain too. I had a hard time keeping it in place while sandwiching the two sides with the center frame and installing the screws. The installation manual is available here on line in the lower portion of the description. It would be worth reviewing to determine if you can manage the job or have a professional do the work for you. Might not have been such a bad idea if I had to do it again. It might be easier too if this is a new installation! As for the door itself, it has 3 flaps consisting of an opaque flap on the interior and exterior with a foam flap in the center. Very nice door but the dark center flap does not allow light to pass through it creating an illusion to the dogs that the door is locked! After years of being able to see light through their door, means it’s good to pass. A dark door means the door is locked! Because the center foam flap keeps light from penetrating, they stare at it in confusion then look at me, like dad, the darn thing is locked, open it! They don’t like it and it is taking some definite work trying to convince/trick them that it’s okay to pass into or out of the door without seeing light! Poor things! I’ll keep trying though and I’m sure they’ll get used to it, but be aware! Even with all this, it is a great door, I would recommend but because of all that I went through I have to give it 4 stars. Maybe I’ll update after the dogs get used to it and after a winters abuse. Update: This door has been installed for a year now and I still cringe about what a pain in the butt it was to install but it's working great. I live in CA so the weather extremes are not too bad. Don't let the manufacturer fool you!! If you have above average carpentry skills and most importantly, the tools to tackle the job then go for it. My skills are above average. If you're installing into an existing hole, there will be cutting! Unless you're a contortionist the door will need to be removed from the hinges. If you have a spouse, send them away for a while because there will be cursing! But wait, you will need a second set of hands for the install. Don't forget to replace the plastic screws with ss steel screws, buying them extra long for trimming. Laying it out is a whole other story, doing it in a steel door is even worse. I digress, my point is, if you don't have the skills, hire a professional to do the install!! You'll be happy you did and so will your spouse. It's a great door and I don't want to discourage the purchase, just buyer beware! On other thing. I have two dogs. One has figured it out really well. The other still doesn't like it and would rather be let out of the slider. She will use it though out of desperation...

Great product and very easy to install. not for fat cats ;-)

This insulated kitty door is working great! 🥳 It really doesn’t let the cold or the heat in. 😮 We got the medium size because we have larger cats. I also discarded the screws that came in the package and got a couple packs of the ones below from Lowe’s instead. #8 - 32 x 3-in Phillips/Slotted combination -Drive Machine screws (Lowe’s Item #57850 , Model #491295)

Living in the Midwest we were excited for a cat door that would keep out the cold, but it actually works worse than the regular one we had bought before. Drafts still come through unless it’s covered, but the cat goes in and out at all times day or night, so that’s not realistic. We created our own custom fit insulated board so it could fit inside the lower half of our bedroom windows. The one in our bedroom is the original with just one plastic piece. It’s great, no leaks, no drafts. I’m not sure if we just got a faulty one, but the one in my daughter’s room leaks a lot, the doors don’t close all the way with the magnetic closing mechanism. I did give it two stars because the cats have no problem getting in and out. They could care less if it’s cold! We were wondering how they would adjust to the heavier door to get through, but it was never a problem.

Works great, seals the hot/cold out, and the flap functions well! It’s the perfect fit/size for our door! Well made — should last a while with extended use. No more scratches all along the door frame, and ease of access for all of our pets.

En climas extremos, funciona muy bien ya que mantiene el calor fuera y el aire acondicionado no se escapa por esta puerta. Se tiene que ajustar el borde del aislante, cortando el excedente necesario, ya que pega en el marco exterior y hace que no baje como debe. Una vez haciendo este ajuste, funcionó perfectamente. La tapa de seguridad, si se coloca a presión, es un poco complicada de retirar. Es mejor solo sobre poner. Pero en general, excelente producto y funcionamiento.

It never shuts after the cat gets through....it doesn't matter how much you fiddle with it

The installation instructions are very clear and quite simple. We installed it on our storm door, which was a bit too thin for the pieces to fit snugly together, so we had to fit an additional wood frame as “shim”, to make it work, but it was not a big issue. The dog loves it, and it is not “draughty”, the extra insulation layer in the middle is effective in blocking cold draughts.

Amazing cat door Zero air breeze. Perfect for winter Well built Super impressed Easy instructions. The small one is perfect for my 14 lb cat

We bought this door to keep the warms in and it works. Yes, it‘s a little noisier but we all got used to it within days.
