DualScan Microchip Cat Door - Door Opening is 4 3/4" H x 5 5/8" W

We have one big old senior cat (19lbs) who comes and goes as he pleases - he never leaves our yard. We also have a younger, far more adventurous cat that is not allowed out under any circumstances - he will jump the fence in a heartbeat and disappear for two days. So this was a perfect solution for us - with one big question mark. Could our senior cat even fit through the hole? It's a very small opening, and there's only one size to this. I tested him before I bought this door - I cut a flap in a cardboard box and put some treats in it, and he squeezed through just fine. (Ironically, the treats are how he got to be so fat ...) This door was bought to replace a manually operated door, which we used before we got our younger cat. It fit in the same opening, which had been cut into the aluminum panel at the bottom of a storm door. Despite the fact that the instructions cautioned against interference if mounted in metal, it was worth a shot because the hole had already been cut. Mounted like this, the performance was inconsistent - sometimes it worked, sometimes it didn't. I called the company to see if there might be some other cause i could look into - they listened carefully and were very certain that this was the problem. They recommended the circular mounting bracket that will offset the sensors from the metal by an inch or two, which they say is enough. Instead, I found a nice piece of plexiglass in the garage, left over from another project, that I repurposed as a window to replace the aluminum. The installation is very straightforward - but it does require a little bit of skill. Basically, it's "trace the hole, cut the hole, push one end through and stick the other side on with two screws and you're done!", but the trick is in cutting the hole. Initially (with the original door) I just traced the hole and cut it out with a pair of tin snips. The plexiglass was a little trickier. Going through a wall or an exterior door would require some thought for sure. I measured the size and cut the plexiglass on a tablesaw, but I put masking tape on both sides to prevent chipping. Same with the cutout - I traced out the rough size of the opening using the door, then used masking tape on both sides. I made a more accurate line with a marker, drilled a couple of pilot holes and cut the opening out with a jigsaw and a fine-tooth blade. Electronically, it works great. After a little encouragement, our old-timer just sticks his nose up against the little window and we can hear the "click" that unlocks it. I think he has learned to listen for the click himself. We'll see if the other cat figures this out and tries to follow close behind - I wouldn't put it past him. There's a locking mechanism that offers all possibilities. It can be locked both ways, or open one way and locked the other (right now we have some rodents in the yard; we have it set to let him out but not in; we want to check first to see if he's bringing in a mouse or rat). It can also be set to let him in but not back out again - which is great for keeping him in at night. It can also be unlocked both ways for the cat with the right chip, or unlocked and completely overridden to let anyone in or out. Once again, the big downside is the size; it's really tight for our cat. The company assures me that they are "in production" for a larger door, which I will probably buy once it's available.

I bought two of these for three cats. We have a two cats that we want to keep indoors and one who is an outside cat who needs to come home for food. All have microchips from 3 different companies. All can activate the cat doors. We have the cat doors in a thin metal lanai door and a thick metal-lined wood door. Both cat doors work with both doors. One cat has always been a wizard with picking at "locked" cat doors and has not been able to prison break these doors yet. They are multidirectional. You set each cat as "indoor cat" who can only come in, or "outdoor cat" who can come and go. One cat is scared of the click the door makes when it unlocks and he still doesn't use the door much. The 3 legged one figured it out in 2 minutes. We then have a large shy mostly outdoor cat. He seems to have to stick his head in really far for the microchip to activate it. In the end we bought a collar and bought the sureflap microchip tag (2 for $10). This is a great product so long as you are patient with training your cats. We put treats on there until they got the hang of it. We bought (and returned) a different brand as it was enter-only activated and did not restrict them leaving. With 2 doors we can control who goes on the lanai as well as who comes and goes outside. They are normal cat door sized so may not fit a very wide cat. I would recommend programming the door before you put it in your door so that you can just move it over your cat beforehand. I can't see a backup battery but you are able to change the main batteries without having to reprogram it afterwards. There are great manual locks on there too if you need to temporarily change access during bad weather etc .....two weeks later and all three cats are happily using the cat doors (even the one who isnt very smart) and there is peace again in the land :-)

Orderd this device on 10/19/2019. I have had no issues with this device and my cat never complained about it. It did take some time to train our cat to go through the door since she is not regular cat food motivated. She is a rescue and is very particular about her food, basically she loves garbage food over high priced food (will not mention companies). I have read some of the other negative reviewers and looked at their videos. I do not agree with most of them. Had this device for a while and is it loud opening and closing, I guess it is if you have supersonic hearing. The door will make a clicking sound that is no louder then our kids typing on their phones. Door size, cats are cortortionist and they dont care about the door size they just want to go outside. Now if ur cat controls ur household and u feed it as much as they wantyou too, then that is not the size of the door that is the problem. Could the door be larger just for the comfort of the cat getting in and out, yes. A smug bigger would be great but I am sure it would cost more. Funny thing is they now do have a bigger dog one, so if you want too go bigger because of cat complains get the bigger small dog door. I think some people said they rather go with other doors and i have ordered other doors and don't like that they are not raccoon proof at all, this door is and they have tried. Last thing if you install it wrong the door will not work properly, meaning if ur door is thicker then the device you will need to get the extender. It says that in the instructions, so read them before you comment. This is why I dont write reviews right away, sometimes it takes me years. In all this is a great door that I have had it for a good while and one of the springs failed for the opening mechanism on this filthy looking door. I regret not taking a photo on how filthy it looked but it took me 3 days to clean it and get new springs into it and now it is back to working perfectly fine. Cat was not happy during this time. I did take a photo of two of the 3 rusted springs as the 3rd completely disintegrated. I personally did not think that this device would last as long when i originally got it, for it to last 5 plus years is a wow for an electronic device. I was thinking 2 years tops but the engineers on this know what they were doing. The only thing I did wish this device did is have a permanent slide type plastic when it comes to winter. I feel the seal feather strips are not the best where i tape the whole door in the winter. They do what they are supposed to do just like they do one our regular windows but on this I personally dont think it's that great. I will be using this door for another 5 years plus in the same spot of the house. I did get this companies new app activated door, which I will install soon and noticed a great differences, like a silicone seal on the battery door. No more water / humidity getting into the battery compartment. This just means thay this company does improve their products over time to make it last even longer. So to that I will say thank you guys. AND NO I AM NOT SPONSORED BY THIS COMPANY IN ANY SHAPEWAY OR FORM. To the engineers I think what placing some caulk on the outside compartment would fix some of the other negative reviews.

We bought this door so our 3 outdoor cats would have access to our garage where we keep their food, water, and warm beds for winter. We had a one-way door before and the raccoons figured out how to get inside so decided we needed to upgrade to the dual door. We continued having raccoon issues and were convinced that they were finding other way to break into the garage because this door was impossible to open. After many, many months of dueling with the raccoons and continuously finding them inside, we installed a camera in our garage which caught the sneaky things opening the door from the outside to get into the garage and then opening from the inside to get back out. As far as functionality for the cats to get access, the door has been great. Our cats are microchipped, which works seamlessly with the door (much better than our one-way door). The ability to lock certain cats in or out based on the microchip has been handy. And the flap locking feature is also good when we have a vet visit planned and need to collect all the cats to be able to take them - I just flip the door so they come in and can't go out in the evening and they're collected inside by morning. Unfortunately, none of that great functionality is important if it won't keep out pests.

i LOVE this door! I don't get why anyone would want to return it. It's great to keep your cat safe from wild life (racoons) or strange cats from entering your house or barn. It works off a microchip in your cat and will only open for him/her and then locks behind them. You can program up to something ridiculous like 25 cats. You can manually lock the door (i.e. you are feeding them their evening meal, and want to keep them inside, turn the knob, lock the door). Or you have a wayward cat that hasn't made it home yet, but you don't' want anyone else to leave, turn the knob to "enter only." You have a cat you don't want to go outside ever. You never program their microchip so they can't use the door. This door never failed. It operates on AA batteries and has a low battery power light to warn you. Instructions are simple. If someone returns this door it's because they are lazy and don't want to train their cat on this door. Yes, it takes some of that, but I am here to tell you, invest the time to teach this to your cat, and you will sleep better every night. My cat was skittish of other people. He was a barn cat, but I took the time to let him know me, and he allowed me to train him. He flies through this door faster than a cat doing zoomies in your house now. Best investment i made into my safety, and my cat's safety. Easy to install, sturdy, durable, and great battery life. Yes, there is a click as the door reads your cat's microchip, but that's also a training aid. They learn they have to hear a click and then the door works. And if they are like my cat, who never went through a cat flap till this door, it took him some time to get used to the flap sliding across his back. But cats are smart. They get this. Too bad some people don't.

The devil is in the details and if those details are not presented then you better be prepared to be disappointed. I bought this product because I have had problems with racoons coming through the existing cat door at night. What I really needed was a cat door that would simple lock access from the outside during the evening hours. Unfortunately that is just too simple of an idea for any manufacturer of pet doors apparently since I could find nothing even close to something like that. The best solution was a pet door with an RF tag reader so I decided to take a chance on this product. When it first arrived, I was pleasantly surprised and happy with the quality of the build. It is solidly constructed with hard quality plastic for its case and a nice strong, tight fitting flap. I was also pleased to see that it fit inside the existing cut I made in the door for the previous pet door. The previous door was taller and a four inch gap was left between the new pet door and the top of the old door cut. This was no big deal and I had expected this before I bought this product. I had plans on blocking and filling the gap once I had things set up so no disappointment there. I easily installed the door, purchased some batteries and this is where things began to go south real fast. In short, there were two major problems here. First and foremost of the problems was the fact that this product has issues with metal doors. My door just happens to be made from two metal sheets that sandwich an inner foam layer. The instructions point out that the product could experience reduced range in reading the RF tags but should still work well enough with most metal doors. This little detail, had I known about it beforehand would in all likelihood have swayed my decision away from buying this damn thing in the first place. Of course there was no mention of this the product description (thank you Amazon). The manufacture offers a work around to this problem by providing a large round plastic adapter (sold separately) which centers the door away from the metal edges and requires additional cutting into the door. I was skeptical of buying anything else from this manufacturer and not really in the mood to chop up my door any more than it already is. This brings us to problem number two: the cat hates this door. I tried everything I could to get her to acclimate to the new door but nothing worked. At one point I had to gently but firmly push her head in enough to allow the door to read the tag while in the learning mode. Afterwards I got the thing to unlock only once from the inside and never did it work from the outside as the cat was pressing on the door with her head with gentle prodding from me. In order for any cat to access the door it has to basically squat down as it passes through. Some cats might not mind but mine would have nothing to do with it. Now problem number one was working in concert with problem number two to make the whole situation a complete failure. I left the door in for a few days just to see if either the cat would come to accept the door and/or if the door itself would work as designed. No go. So even if I could have solved problem number one by purchasing and installing the adapter to get the door to work, it wouldn't have made any difference in the outcome as the cat was just plan uncomfortable with the ergonomics of the door design. Finally I decided to remove the door which normally should have come out as easily as it would be going in. No. One of the two screw would not come out all the way and I had to end up cutting it with a small Dremel grinding wheel which ended up damaging the mounting ring thus voiding any chance of selling it off to someone who might have use for this product. Even after I cut the screw I had do disassemble the thing to remove the remaining piece of screw that would not back out. So what I got for my $160 purchase was a nicely built piece of quality plastic destined for the local landfill and a new found reluctance to ever order anything more from Amazon or anyone else online. My only advice for anyone who wishes to order online is to see if you can download the instruction manual in advance and read it first before throwing away your money as I ended up doing. 160 lousy f***ing bucks Amazon! That stings, and I will remember this for a long f***ing time.

Update: it's been two weeks and the cat has now mastered the door! The cat has to learn to push the door with his head not his paws. Every morning i lock my cat in the utility room till he figures it out. First day was 5 hours, second day was 3 hours. He's not a stupid cat, it just isn't natural for them that a door will open with a head push but not a paw push. However to be fair It appears most Microchip cat doors have this flaw, so all of them are hard to make work. See below for a mounting tip to make it easier to learn . Moreover when it does stick its head in first the machine makes a large snap sound and the cat pulls his head out and it locks shut instantly. Wouldn't you? The other really really stupid design flaw on this system is there's no way to use this as simply a cat flap without the electronic gating. There's four modes of operation and all of them allowing the cat to go through require the electronic scan to work. This would be so much easier for the cat to learn if there was just a mode where the cat flap could just be a normal mechanical cat flap. Finally if the batteries or electronic fail on this the fail mode is locked rather than unlocked. So if you were away on vacation and it failed then no raccoons can get get in but your cat dies because it's stuck outside or inside. So massively bad design concepts. I decided on this dual scan model after reading reviews of other scanners. Some scanners only scan for entry, which is all I wanted because I only need a raccoon and mouse excluder. But it turns out raccoons can manage to pull the door out on those with no gating on exit. Hence I needed dual scan. I read about the petsafe one with dual scan and It has the same dumb design flaws this one plus a second problem in that clever cats can spoof it so that they can get both in and out even if only one if those privledges is granted. For me that would not have been a problem as I'm not trying to keep my cat inside, just raccoons outside. In hindsight I'd have bought that pet safe brand one as it was cheaper. It appears that how fast your cat can figure out that a head push is required may depend on the height you mount thus in the door. I had no choice that mine had to be about 6" high off the floor due to the door design. Evidently if they have to couch down to get it the idea of pushing head first rather than paws first will se more natural to the cat. So for training I've put in a booster block in front of the door so the door is at ground level for now . But obviously I can't leave that obstruction in my doorway forever. These design flaws annoy me because a better electrical engineer could have made it so the rfid detector had greater range and did not require a head push to work. Such incompetence! And the lack of a fail-unlocked mode or a general unlocked mode is just begging for a dead cat lawsuit. But the bottom line is that my cat is slowly learning to use it. Ive noticed that he learned to go out faster than go in. I suspect this is because when locked in the utility room he's bored enough to experiment with it till a head push works. I'm not sure if he's learning the idea though as this may be just random chance that he uses his head occasionally. For going in the sets no confined space so I think he just doesn't sit there and try it over and over as he can he can something else like howl at the window to get my attention. Only when it rains does he make a concerted effort to get in. So the good news is it does work and it appears cats can make use of it but not easily at least at first. As far as I can tell from reading all the rfid gates have the same stupid design flaws. I bought two of these and one of them seemed to have a weaker or non existent detection and so I returned it. So there may be variability in how close the cats head has to be. Other people have reported these things making noise when the cat just walks by it so those must have a longer range. Evidently the quality control on these is poor. It seems to be mechanically well made though. The opening is small but I'd say anything but the largest cat could squeeze through snugly. I prefer tat as it will exclude raccoons and dogs more if they manage to break the latch

"Any sufficiently advanced technology is indistinguishable from magic" - Arthur C. Clarke. As a science type, I'm always happy to share that quote from science fiction writer Arthur C. Clarke (2001: A Space Odyssey , Rendezvous with Rama, etc) because it well describes the wonderment of the times we live in. In this case, who would ever believe that you could have a cat door that recognizes an individual cat and would let them in or out according to that cat's permissions? I bought this cat flap because a (very large) raccoon had discovered that the old flap was a great way to get into the kitchen at night so she could eat all the dog food. Since the cat has been chipped (and the raccoon, hopefully, not) this product was a great solution. It's also some extra peace of mind the next time we get a kitten that hasn't yet earned his outdoor privileges - the kitten stays locked in and the adult cat can come and go as he pleases (without a human doorman to answer his needs). Programming is very easy, just set the flap to "learn" mode and walk the cat through. A flashing light tells you it's successfully learned that cat's RFID chip number and you're good to go. The cat's learned to be patient when coming through the door - he noses at the flap for a moment until he hears the "click" and then pushes through. It might be a problem if he's in a big hurry (like being chased by the neighbor's cat which is twice his size) as the recognition takes about a second but he's adjusted to the new door easily. The only problem, and it's hardly a quibble, is that our dogs used to love to stick their heads through the cat door to see what was going on outside. It was adorable to watch as they'd take turns poking their head out to supervise as you watered the garden. While the dogs are also chipped and the door could be trained to recognize their RFID tags, unfortunately the chip in their neck is so far back from their nose that it doesn't get inside the door reader's range for recognition. While a cat's neck chip is probably 3-4 inches away from his nose, the dogs' chips are probably a foot away from their sniffer. Not the end of the world and the dogs have already stopped trying to poke their noses through... This door has completely solved the raccoon problem and will be very helpful the next time we have a curious kitten (or puppy) trying to follow the cat outside...
