SureFlap Microchip Cat Door Connect with Hub Bundle - Door Opening: The Microchip Cat Door Flap Opening is 5 5/8" (w) by 4 3/4" (h

I LOVE this cat door. I don’t know what these other reviews are doing but this is a quality and sturdy door. And I’m particular with what I buy. All the things you can do from your smartphone besides being able to track your cat’s comings and goings makes it worth the price you pay. We have a cat that lives in our shed and keeps the rodent population to zero. With this door I can make sure he’s safely locked in at night and it also doesn’t allow strange cats or other wild animals to even enter the shed, keeping my cat safe from unknown "friends." On bad weather days I can even keep him restricted to inside with no outside access. ALL FROM MY PHONE. Love it! And my husband will say it was easy to install and to get it up and operating. One of the best inventions ever made when a cat mom is stressed whether her cats are safely tucked in bed at night or bad weather!!

Your cat can easily get trapped inside or outside!!! Mine got trapped outside on a vacation and had to scavenge food!I've had this cat/pet door for a few months now and my cat got along with using it just fine, using tape to keep it open the first couple days did the trick. The door has been working fine and seemingly reporting the cat going in and out. Though sometimes not reporting the correct inside/outside, I believe this is when the cat goes through the senors too fast?It seemed to be fine, while I was around town I was getting notifications. I decided to trust this product. I was wrong. Now the problem... I put in new batteries before I left, I went out of town for about 10 day, the app was only reporting the cat go in/out once a day! Even on a normal day when I'm not around (at all) the cat goes in/out about 7 times. After the fourth day it stopped reporting the cats movements. At this point I believe the cat got trapped outside! Without food! Battery life still good, the door was still being detected by the wifi. A day or two went by and I got a notification from the power company that my power went out briefly at night then door stopped responding to the wifi! My cat luckily was stealing food from my dogs(that were being taken care of in my back yard) and likely from neighbors cat food dishes.I get home and yep the cat door isnt working, the cat is outback hanging around my dogs. There's a high pitch noise coming from the cat door. No idea why it stopped working.I feel so bad for my cat(<1 year old). I bought this expensive cat door and wall insert, cut a hole in my wall and now I cant even trust the dang thing on vacations.

Definitely a life saver, extremely impressive and easy to install.We have an automatic feeder with WiFi / camera for if or when we leave on short trips. Unfortunately the day after we left on a longer two week trip, I saw on the camera a stray cat chasing my cat away and eating all her food - every day. I couldn’t do anything as I watched my cat starve (not really starve, cats are survivors but what an inconvenience for her). That’s when I purchased this great product and a pellet gun! Easy to install, easy for my cat to use (only my cat can access her room), great app that’s easy to use, with lots of extra features including notifications and tracking. My kitty now has her own safe space without having to wear a collar that could possibly get hung up or lost. Absolutely love this product and highly recommend it. It made my new pellet gun completely not needed. See? It saved my cats life from starving by giving her a safe space and her own food. And it also saved that overly aggressive stray bully cats life that was taking her food for herself. Life saver!!!! Anybody what an unused pellet gun?

We got the flap connect professionally installed but we had a couple of issues with the product. First, the flap magnet was not strong enough so the door did not close properly which allowed our inside cat to sneak out through the door. When I called the customer support they sent me a replacement door with a stronger magnet which seems to do the trick but then we had one more issue where the batteries would completely drain in less than 2 weeks. I was told that the entire unit could be defective and that they would send me one more replacement unit but it took more than 3 months to get it as the support said the product was coming from somewhere in Europe. I was a bit skeptical if it would truly work again (by now we were way past the return window). We spent over $2000 to get a new back door installed just so we could install this product and not being able to use it for almost 3 months left us with a lot of frustration. It's been a month now since we got it re-installed again and thankfully this time it seems to be working as expected. I shall post an update if anything changes.Pros: Love the ability to monitor all our cat's door usage through the iPhone app and also control the unit remotely. I get cute "meow" alerts whenever one of our cats uses the door.I like the feasibility to either use the app or manually lock/unlock the doorCons: Setting up the app initially can be a little tricky, I wish the original product came with a stronger flap.Tip: Do not use regular Energizer or Duracell AA batteries. get the Ultimate Lithium one as they seem to hold the charge better.Update: 12/25/19 : The battery issue still seems to persist but not as bad as the first unit. Second unit gave us around 1 1/2 to 2 months of battery life compared to 2 weeks. The flap’s latch stopped working and our cats were no longer able to come in. As a temporary workaround, I put a tape so our cats could open the door from outside but this also means any small animal could come in. The SureFlap customer support sent us a replacement latch but that did not help. They ended up sending a new unit ( 3rd time) which I installed today. Will post an update in few weeks on how this 3rd unit is working. That said, I am very reluctant to recommend this product to anyone who intend to use it during vacation as I would freak out if my pets cannot come in. This is a great product and I am hoping that the manufacturer takes all the issues into consideration and improves the product.
