Introducing the SureFlap Microchip Activated Cat Door

SureFlap Cat Door

If you have indoor/outdoor kitties and you use a cat door, have you ever walked into the kitchen to find the neighbor’s cat chowing down? Or maybe even some other kind of critter? That’s the problem with regular cat doors, they let the whole neighborhood in.

I’ve seen cat doors that are activated by a tag that kitty wears on her collar, but this is even better. The SureFlap cat door is activated by your cat’s microchip, so there are no collars or tags to loose. Easy to install in any door or wall, you simply set the SureFlap to recognize your cat’s microchip ID (it can memorize up to 32 IDs!) and then when kitty approaches the door it automatically unlocks. You can also manually lock the door to allow cats to enter only, exit only, or prevent both entering and exiting. The system is battery operated and includes a low battery indicator when it’s time to change the batteries.

SureFlap Cat Door

Another interesting use of the SureFlap is to limit access to certain areas of your house for specific cats. Just install a SureFlap on an interior door or wall and program it for the cats who are allowed to access the area. This could be used to allow only certain cats access to special food while others are kept out.

The SureFlap was invented in the UK and is now being distributed in North America for the first time. It is available in Canada at veterinary clinics and pet supply stores and both Canadian and US residents can order online at The cat door itself sells for $189 CAD. Additional accessories include tunnel extenders used to mount the door in thicker doors or walls, for $20 CAD each, and a mount adapter, which is needed for installing in a window or wall, for $26 CAD.

    What a great idea! I spent a bundle getting my mom one of the collar-activated doors, and her cat promptly lost the collar. So she still has neighbor cats (and raccoons) coming in. Thanks for pointing this out!

    I’ve had this catflap since last summer and it works great! I really recommend it.

    My larger cat had some trouble at first learning how to enter correctly to have her chip read quickly (her head filled the tunnel so the chip was out of reach), but now she is a pro. She stick her head in at the right angle hears the click and comes in. No more neighbourhood cats in the house!

    My new kitties just learned the flap last week. One was a little afraid of the noise at first but has since gotten used to it.

    Finally I should say ;-) ,
    We are looking since year for this alternative as it will allow cats more freedom without having to wear a collar which can be dangerous.
    Unfortunately till now the models we saw where all incompatible with the hole ( from our actual IR cat flap) in the window.
    I hope it comes soon to Europe.

    I have this flap since almost a year now. It does exactly what it promises. It’s worth every bug. Giving me the safety that only my cat can enter. There’s also another product on the market that has a light sensor to lock the door (in or out) once it’s getting dark, but it’s much more expensive (at least here in Germany). So far, I never had to change batteries, still works (but I did not use the packed Batteries, used some Duracells).
    The door makes a noise when the cat comes into the reach of the sensor, but at least my little garden-warrior got used to it very fast.

    This is awesome. I keep my bedroom door closed most of the time (roommates), so it makes it difficult for my kitty to come and go as she pleases. This seems like the perfect solution.

  6. 6

    wow, this is fantasic! i have no need for this as my cat is indoor only, but i am very impressed by it.

  7. 7

    Very cool! I love the microchip idea. Much better than a collar/tag that can easily be lost.

  8. 8

    Now if they could just figure out a way to check what might be in the kitty’s mouth before he or she comes in … ! I’m sure mine would just LOVE to bring in a mouse/gopher/lizard/bird kill to proudly show off to Mom. Great idea!

  9. 9

    Wow, what a great idea! Wish it was bigger, though. Our basset puppy is the only one who is microchipped because she came from the Humane Society. All of our cats were strays.

    Dear Minkamau,

    Over 20,000 units have been sold in the UK and Europe since its introduction in 2008.
    Have you checked to see if the Mount Adaptor is big enough to cover the existing opening?

  11. 11

    Dear Naomi,

    In 6 – 9 months a large cat/small dog size is scheduled to become available.

  12. 12

    Great idea! We had an older version where my cat wore a magnet on her collar, but this is much more secure.

  13. 13

    Great idea! Very expensive, but maybe if a lot of people buy it, the price will come down? Yeah, RIGHT.

    I bought a remote control cat flap for my diabetic cat who was dealing with cancer. I have multiple cats, and wanted to feed her extra food to help her deal with her health issues. I could not leave it out or she would not benefit. Unfortunately the flap made so much noise unlatching that when she went through, all of the other cats would come running and follow her in. One day I went in and found all six cats in her room.

    Just because a flap will only open for one cat, doesn’t mean other cats / animals can’t learn how to get in.

  15. 15

    I’m trying to buy this right now, and the code 150410 isn’t working. Can you check with SureFlap and see what’s up?

    I’m itching to click BUY!

  16. 16

    OMG! That is so cool!

    Dear Jonquil,

    Thank you for pointing out that the discount coupon is not working. We are working on getting it up and running as soon as possible. Please accept my sincere apologies for the inconvenience.

    The discount coupon is now again functional. I look forward to your order, Jonquil.

    Dear Connie,

    I am sorry to read about your experience with a remote control flap. Our microchip operated catflap can be programmed to close within seconds after the animal has gone through.

    If you are interested I will gladly work with you to see how Sureflap operates to accomodate your requirements.

    We will offer a full refund if you are not satisfied.

    This make so much sense!

    I’ve been waiting for exactly this product. Sadly, this is out of my price range.

    We have 2 cats who need to be restricted diets. Something like this would ensure they can be fed separately without time restrictions. Seems like we would need 2 flaps to make it work though. $189 is far to expensive, let alone double that.

  22. 22

    Thanks for posting this ! I was waiting for this to make its way from Europe to the US/Canada. Maybe this also helps with more people getting the microchip for their cats :)

  23. 23

    Great idea! We had an older version where my cat wore a magnet on her collar, but this is much more secure.

  24. 24

    I bought this about 6 months ago and my cat still won’t use it. As soon as it clicks she runs away. Any ideas how i can get here to use it?

  25. 25

    Wonderful product! Works great for all indoor cats also….lets me have a room with food where the skinny cats can go eat any time of day, but the fat cats can’t get in! I also have a special needs boy, he can stay in his safe padded room, but other cats can go visit and play with him.

    For Lisa, Start feeding your cat near the door without trying to get her to use the door. After several days when she’s used to eating there, put a couple treats in the tunnel so she has to stick her head in to eat them. Keep doing that until she learns to ignore the click and get the treats anyway. Then she should be OK to go right through!

    I have one of these and it works great, I leave my cats for a couple days regularly due to work and now they can’t bring in any friends when I’m gone. Just remember to change batteries when it starts blinking. It is worth the price when you consider what one stray can do .

    I had touble getting one cat to go through at first so I just put him in the room with cat door and shut room door then put canned cat food in tunnel…he figured out what to do. Also bought a small doghouse and cut hole in rear and put it up against outside wall so they can have a little better security when exiting. Maybe you could design a small cathouse or porch to connect to tunnel. Lots of smart predators out here in Wyoming.

  28. 28

    Great thought!

    Is exiting controlled by the microchip? Very important to have the door locked so raccoons cannot pry it open from the outside. (They are exceptionally clever.)

    Thanks, Pamela

    I just purchased the Sureflap Mark 5. It has a quieter latch, weather stripping and a claw proof door so intruders can’t pry it open from the outside. This is my first Sureflap. I got it because possums were coming in the old cat door.
    The majority of my 5 of my cats are having trouble using it, and some of them are “acting out”. It is too small for them to comfortably squeeze through. And the old one (22) who isn’t fat, just hurts when he squeezes through it. (He hisses every time)
    We have been working with it for a few weeks now. I propped the door open, lowered the latch and took the batteries out of it. I raised it to belly height and put larger landing platforms on either side of it. It is in a window exactly where they have had a regular cat flap for the last ten years.
    Do you have any suggestions and when is the new larger model coming out? I need it baaaad. I would buy it this second if I could find one.

    Please Peter, give me some good news.

    Oohh, I’ve been waiting for this! Have discussed the need for exactly this many times with different people. The price is painful but I’ll have many years of different uses from even one.

    I heard of this idea years ago, and have hunted since to find a company in the USA that sells this system. I was amazed at how inexpensive it was. I did hire a friend who is a plumber/heater and woodworker to insall it in the side of the house. I highly recommend doing the same.

    I live in an area that has a lot of cats, but is very safe for them outside. So I found I was feeding the entire neighborhood, and that my cat was never able to get away from them.

    I have heard and seen some of the neighborhood toms try to get in. They cannot do it, and they have tried some frighteningly fierce digging. My cat has calmned down a lot since Christmas, when the door was installed.

    BE PATIENT with training, it helps if they already know how to use a door. They don’t like pushing with their heads at all. But mine learned in a few hours, and it’s been a wonder for her and for me. Oh, and if something happens, it does let ANY cat OUT, which is a nice safety.

    SureFlap is ingenious and now an essential part of my pet-owner life. Thank you so much, I’m sure I”ll be back for more!

    My older cat – 13 lbs took to this right away. However my younger cat – 14 lbs has a different body shape and he has to literally pull his hindquarters through. I know there are many bigger cats out there and a second size (LARGER) really is necessary. So my youngest won’t use it but the other one is happy with it. He seems to know it should open the other way but I want him to stay in once he gets in. I personally love the fact this works off the microchips since collars can get lost or pulled off all too easy. I highly recommend it but encourage the manufacture to make a bigger size.

    I have a large cat (slightly less than 20 lb), who needs an cat door bigger than the ordinary dimensions. Do you sell such a product?

    I purchased two of these about a year ago and mounted them on my porch door.The concept is great. However, I have found a few problems. First of all as perviously stated it does need to be larger. Secondly, it does not function from both directions. I have an indoor/outdoor cat that started as a stay here a number of years ago. But I have four indoor only cats. So I had to purchase a second unit and mount it backward so only the one can exit. Thirdly, I have a young male (not chipped) has learned if he hits the “reversed” unit from the inside real hard in the lower corner, the flap will flex enough to allow the door to release. And he is gone! Currently I have to manually lock the exit door at all times or keep them locked in the house. So unfortunately my main goal to allow the outdoor cat to come and go as he pleases has diminished. I can not even let him come in because he gets claustrophobic and will bust out my screen if he cannot exit the flap. I hope future models will be much improved.

    I purchased this door but I’d like to see an addition made for this – a facial recognition gadget that could be attached to the door to ensure that our cats do not carry in rodents. I woke up to a dead rodent this morning, courtesy of my sweet little kitty. She brought a small mouse in last week which was alive and which we have not found since scurrying off! She’s brought in a bird and several mice. We’re at the point where we won’t be able to let her use her cat door any longer, but if you could come up with some kind of webcam gadget that would only allow entrance when our microchipped cat comes up to the door – rodent free. I’d gladly pay for the upgraded equipment! Do you have any plans on doing so?

    We installed one in January. Before that she was too small to have an id chip inserted. She demonstrated her willingness to use a flap weeks earlier when some work on the back door involved removing a glass pane. At the vets we checked the id chips available were compatible with the sureflap. The flap was programmed before we returned home. Food in the flap programmed the cat. Though for the first week she considered it house access only. Inside she’d try to pull the flap in or would move to and from the flap making the lock click. It was a good game and to this day she will play this I believe to tease stevie (nextdoors cat) he can’t get in, he hasn’t the key. Using masking tape I held up the door in the out position. She realised the door was two way. Before that it had been trial and error. It took two weeks for the message to click :-) so to speak.

    It’s beyond 6 months on & near time to renew batteries approaching. On changing the batteries will the sureflap need to be reprogrammed? Or does it hold memory for a seconds. The book states to reprogramme the sureflap should have it’s batteries removed for at least 2 minutes. Reprogramming for one cat, it is not a big deal. Just curious how someone, the 32 cats might fare?

    I bought one best thing ever no more intruding cats only problem 2 of my cat’s user it the other who is always nervous won’t sftet a week I’ve tried everything any ideas please

    I also have the same concern that Connie expressed – I see the value of the microchip security for keeping other animals out, but what about a neighbor cat who is friendly with mine and follows closely behind?:

    I see on one of your videos on this website that the cat approaches the door, the microchip unlocks it, the cat goes through, but then the door swings a couple of times before locking shut. If this is the case, how will this door prevent a “buddy” (unwanted neighbor) cat from following my cat in immediately afterwards?
