I came across this Hidrosil cat door as we really needed to update our current 25 yr old door. This Hidrosil door was able to work for exterior walls and had other features we were looking for. A clear door flap,and double door look options. Able to lock to only open one way or other and fully lock both ways or leave both directions fully open. Very handy . The kit comes with both inside and outside frames made of plastic. Door flap is clear plastic with 1/4 in or so of fluffy seal around it, installation screws and a template to sid in cutting the proper size hole,also instructions. Our existing hole was almost right size and we already had blocking installed in wall so just some trimming was needed for us and moved side blocking back a bit into wall cavity to let door swing nice and free. We used a oscillating tool but utility knife would worked to cut drywall. The inside door frame has a inner lip about 2 in deep.not enough to seal off wall cavity if used to go outside so suggest you block the entire cavity “tunnel” area off some how. Just to be safe. The door flap has a magnet setup along bottom edge to keep door somewhat in place so its not swinging free all time from wind etc. Our install went smooth. Door swings nice and free ,cats can see through it, its not perfect weather tight but will keep alot cold air flow down. Not sure how one could make it totally seal as it has to open both ways easy.
It been 30 min and they already brave enough to go in and out to cat pen. Overall we very happy, nice quality,nice looking works great, should last long time. Was perfect choice for us.

I recently installed this large cat door for my indoor-outdoor kitty, and I’m genuinely impressed. The clear door flap is fantastic — my cat immediately understood how to use it, and I love that I can see her coming and going without guessing. It’s solid and flexible enough for smooth, quiet movement, and it doesn’t slam or stick.
The multiple locking options are excellent for controlling access. Whether I want it fully open, fully locked, or only inward/outward passage allowed, the choices are intuitive and give great peace of mind. The locking mechanism feels robust and secure — no flimsy plastics here.
Installation was straightforward with clear instructions, and the frame seems very durable. It fits well in a standard door and could easily be adapted for other surfaces. My cat took to it instantly, and so far it’s been reliable in all types of weather.
If you need a large, secure, and user-friendly cat door — especially for bigger or confident cats — this one is a winner. Highly recommend!

This cat door is something I am glad to come across as the material of this feels like it was made from a hard type of plastic as I do plan on installing this on a wooden door on where my cat litter box is being this will definitely keep my dog out of the room i don’t want her going in because every chance she gets she try’s to eat my cats poop so ya I am glad to come across this as a person no question can use this for many different reasons I am sure. With that being said i don’t have much more to say than I am happy to give this a good rating from what I can see.

This indoor cat door has transformed movement between our kitten zones. Installation was straightforward with basic tools, and the fit on a standard interior door is secure. The flap is lightweight, making it easy for even small kittens to push through—no hesitation or fear. Quality is solid: durable plastic, smooth edges, and a clean look that blends in. It’s held up well over weeks of constant use. For a rescue, the value lies in reducing stress and promoting independence. The ease of access supports behavior training and socialization. Functionality and fit are spot-on. A simple upgrade with big impact—we highly recommend it for multi-cat homes or fosters.

This is great quality. It’s excellent they provided the ability to use on various thicknesses. There are magnets built in to ensure the door comes to a complete close.
We’re going to attach it to a piece of wood and stick it into a window where they are already able to climb in and out of with ease. Now they can come as they please! No more opening and closing doors and waiting for their spoiled behinds to decide to waltz in at their leisure.
Bonus points that you can control which way the door goes. So, I can let my cat out with the option of keeping one inside while allowing the other to come back when he needs to

Small cat door and would do best for a inside spot.. has alot of gaps for the door itself to put for indoor outdoor due to lots of drafty spots around the door itself even with the brush around it . If you have a large cat you may want to consider a larger door! This would be great for indoor doors or walls and small to medium cats. The locks do lock tight which I wonderful!

I ordered this for our door that leads to our basement. My silly himilayan cat has an issue with closed doors. She needs nothing in the basement, but if you close the door, she’ll run from any room in the house to sit in front of the door and shout until we open it. It’s really quite annoying. lol We ordered this cat door to stop this insanity!! We were worried because it lead to the stairs going down that she may tumble down, but nope! She goes through just as she would if the door were open. The fact that this door is black is perfect as all of our interior doors are black. It’s extremely easy to install and very good quality. We always try them without the door flap first and then add it later once she’s comfortable with the new cat door. We like the quality of this one better that the previous one we bought for the laundry room door where her litter box and food are. (our greedy pug eats her food if we leave the door open) Absolutely recommend this cat door!!!

This cat door works really well overall and does exactly what it’s supposed to do. The collar sensor is a nice feature and helps keep other animals out, which was a big plus for us. It feels sturdy and the size is perfect for my cat. Installation wasn’t too bad, though it did take a little patience. The only downside is that the flap can be a bit stiff at first and took some time for my cat to get fully comfortable using it. Once he figured it out though, it’s been great. Solid product and worth it

I finally got a cat door for our basement door, and it’s been a game-changer. Our Garfield sized cat can be relentless when doors are closed, so giving him his own little portal has saved my sanity. Installation was straightforward with the template and instructions provided. The frame feels solid, the flap swings easily, and even our cautious cats took to it immediately.
The door is a great size for most cats, and the flap is light enough for little kittens but strong enough to stay in place. I love that it has a magnetic bottom so it closes reliably and that there are four locking options—keeping the cats in, out, or letting them move freely depending on the situation. The black color blends perfectly with our interior doors, and the plastic feels high-quality, sturdy, and easy to clean.
It’s versatile too—I’ve seen friends use it on wooden doors, in walls, or even retrofitted into furniture for litter boxes. While it’s not completely weatherproof for full exterior use, it works really well for interior doors and even semi-protected exterior spots. Overall, it’s a solid, well-thought-out cat door that gives our pets independence and makes life easier for us humans.
✅ Easy to install with clear instructions
✅ Sturdy, durable plastic construction
✅ Flap is lightweight yet secure, with magnetic closure
✅ Multiple locking options for flexible access
✅ Suitable for various door thicknesses and even some furniture adaptations
✅ Large enough for most cats, including bigger breeds
❌ Not fully weatherproof for exposed exterior doors
❌ Screw hole covers can fall out if not glued

Hidrosil cat door for interior/exterior doors: This is a great way to give your cat instant access to the outdoors and back inside again. You’ll no longer be your cat’s doorman. They can come and go as they please, provided the bottom tabs are unlocked. When you don’t want your cat going out anymore for the day, you can lock the exit tab. If you don’t want other cats or animals entering your home, you can lock the entry tab. The flap opening is large enough for most cats to fit through. Just check the ad’s measurements to see if your cat is small enough. This door mounted cat door is a lot more stable and secure compared to a screen mounted cat door. Last summer, thanks to my cat continually flying through his cat door, he eventually ripped my screen. With this cat door mounted on my wood front door, he won’t be able to damage that! This cat door is able to fit on a variety of standard door thicknesses, so it will work with your home, too. As well, the plexiglass flap helps to keep dust, insects, wind and rain from entering your home. Allow your cat to roam outside without howling at you to open the door. You’ll both be a lot happier.

I used this door for the opening I cut into an old dining room buffet. I put the litter box inside of it. Before I had a clear plastic PVC flap I made. This is more attractive.
Installation was overall, pretty easy. Considering I didn’t use it for the traditional wall or door opening, I’d say that it was pretty easy. I had to fiddle a little, but ultimately it worked.
One complaint is that it comes with screw hole covers, which is a great feature, but they fall out. I’ll need to put some glue in them to keep them in.
Also, there was an insert with the directions in the box. It showed this door in multiple colors. However, I could not find any other color options on Amazon other than the black. It would have been nice to have the other colors available on Amazon as I think the brown would have looked better for my application.
Other than that, I’m pretty pleased with the end result.

My daughter prefers to sleep with her door closed, which our cats don’t appreciate, so I ordered this pet door. Installation was fairly straightforward. It includes a helpful template for marking the cut lines and pre-drilling the holes. I removed the door from its hinges and used a jigsaw to cut the opening. Since the door is hollow core and I’m not very experienced with a jigsaw, I did end up with a small crack along one edge, but it’s barely noticeable.
The only part I found a bit tricky was getting the screws to pass through both sides of the door and line up properly with the back of the pet door. Once the door was back on its hinges, I needed a second person to help hold the screws in place while I lined everything up.
Overall, we’re very happy with this pet door. It has a magnet that helps it sit straight and closed when not in use. Our cats have already used it several times, though it’s still new so there was a bit of hesitation at first. One of our cats weighs about 13 lbs and the other about 15 lbs, and both fit through comfortably with no issues. I would definitely recommend this pet door.

So first off, immediately upon opening my cat absolutely loved….. the box it came in. But cat’s are going to cat, and that’s one of the reasons this door is so nice. It has two (four) locking options, either lock it so they can only go out, only come in, make the door solid, or let it swing either way.
It has two magnets that hold the door in the closed position against wind, or just to help it close properly (and help gravity) after the cat has went in or out. It is not perfect however, and sometimes it remains open during our testing. In our case it is for an interior wall from within a shop, so we are not as worried about the wind, but I had considered putting it on an exterior entry point and decided against it for this point. We have some other older cat doors that have two doors in them, so when it goes one way, both open, and when it goes the other, only the inside one does. The “advantage” of this style is that they can use a spring to hold it closed in either direction, instead of relying on magnets and gravity.

I didn’t install it yesterday yet, but I checked it carefully and the cat door looks very sturdy and well built. The plastic feels solid, not thin or cheap, and the frame is straight with clean edges. Size matches the description and should fit most interior doors without problem.
The flap moves smoothly and closes well. It doesn’t feel loose, and it looks like it will hold up fine with daily use. The black color is simple and clean, it should match most doors without standing out too much.
Based on first impression:
Feels strong and durable
Good quality plastic
Flap moves smoothly
Clean, simple design
Size looks accurate
Of course, real test will be after installation and some weeks of use, but so far I’m very happy with the quality. If installation goes as expected, this should be a very good cat door. I’ll update if anything changes after installing it.

I ordered this for our door that leads to our basement. My silly himilayan cat has an issue with closed doors. She needs nothing in the basement, but if you close the door, she’ll run from any room in the house to sit in front of the door and shout until we open it. It’s really quite annoying. lol We ordered this cat door to stop this insanity!! We were worried because it lead to the stairs going down that she may tumble down, but nope! She goes through just as she would if the door were open. The fact that this door is black is perfect as all of our interior doors are black. It’s extremely easy to install and very good quality. We always try them without the door flap first and then add it later once she’s comfortable with the new cat door. We like the quality of this one better that the previous one we bought for the laundry room door where her litter box and food are. (our greedy pug eats her food if we leave the door open) Absolutely recommend this cat door!!!

I have 8 little terrorists, and for a long time I couldn’t close my bedroom door, now they can come and go as they please, installing was simple enough with the right tools, the kit came with (almost) everything needed, and the door itself is large enough for my 20 lbs tom to fit through!
