Long lasting cat door 31/10/2015
by Henrik

We've had the PetPorte since 2010, and it has worked (almost) flawlessly for us since. Just a couple of comments:
* Once in a while the green door latch just stays open. If the cat walks through the door again, the latch closes as it should. I have bought a standalone ID chip that I move through the door to close the latch again, so it's no big deal. But is there a way to avoid this?
* The filt strip between the clear plastic door and the housing is really starting to wear down, and cold air is trickling in. Are there replacements available?
* When I bought the door, PetPorte were planning to release a computer accessory for the Smart Flap (at least it says so on the packaging). Do you have any technical details and a release date for it?

> PetSafe Response: Hi Henrik, thank you for getting in touch and letting us resolve your questions. After our discussions, we've sent you a replacement adapter which should solve the latch staying open and have also solved the draft issue. We continue to work on computer accessories and once available we will update the website with new details. Thanks again! :)

Petporte smart cat flap now working perfectly again. 28/10/2015
by Karl Mcilwaine

Further to my earlier review, I have to say I experienced exceptional customer service from this company when my Pet Port stopped working. I received good advice and encouragement to investigate the issue and to solve the problem, all that was needed was a new power supply. It's working fine again now.
Our cat has used the PetPorte for many years, having had it reinstalled in a double glazed window when we moved house, and she loves it. I highly recommend it .

> PetSafe Response: Hi Karl, thank for your glowing feedback, it means a lot to the team here to get such great comments when they've been able to help a customer. I'll make sure it's passed on straight away. Thanks for following up with us :)

Great product - need help with the green latch? 24/10/2015
by kirsty eaglesfield

Our cat is loving his unrestricted access to the outdoors and we are loving the lack of 'intruder' cat visits but unfortunately, like Jan all of a sudden the green latch is not releasing so he is getting stuck outside. We can hear the beep as he is scanned correctly and then just hear him hitting at the door but the green lock won't move down to let him in. We have tried the reset steps below but it has not fixed the problem...
Any other suggestions to get it working? For now we have had to enable vet mode so he can't get out then end up stuck outside while we are in bed or out at work and the customer services phoneline isn't open till Monday morning :(

> PetSafe Response: Hi Kirsty, thanks for getting in touch and we're sorry to hear of the problems you've had. From your description the fault may be with the power adapter. Our Customer Care team will get in touch with you shortly to resolve this for you :)

Are these devices too clever for their own good? 19/10/2015
by Karl McIlwaiine

I have bought several of these over the years and they work very well but appear to be easily damaged. When the early ones failed, they were replaced by the original company (PetPorte). Now the latest one (after several years of satisfactory service) has just failed after it was switched off and on several times during a week of electrical work on my house. The power supply is working (it's warm) but there doesn't appear to be any power to the unit. No response to any of the buttons, not possible to change the mode, nor reset to normal mode. Replacing the battery doesn't help. Don't want to leave it open (by removing the green latch). Replacement is expensive as it is fixed into a double glazed unit. I may well have to dump the unit and look for a cheap (inferior) replacement.
Any suggestions?

> PetSafe Response: Hi Karl, thank you for getting in touch with us. We've contacted you directly via email and together we've identified that the issue is with your power adapter. Once your new one arrives, this should solve the issues you've had with your Petporte and Suki can once again have her own independence without you as her gatekeeper! Thanks again :)

Cat can't get in 14/10/2015
by Jan

My young cat gas finally got to grips on how to use this and all was going well but all of a sudden the green latch is not releasing so she is stuck outside. Please explain to me how I fix this.

> PetSafe Response: Hi Jan, I'm sorry to hear you're having trouble with your cat entering the Petporte. The issue is likely to have been caused by a power cut or power surge to the cat flap.

We have a solution that will resolve your problem, please try the following:
- Disconnect the power and remove the battery
- Hold down the Red button for 10-15 seconds
- Reconnect the power
- Hold down the Green button for 30 seconds
- Replace the battery

The Petporte will now be reset to default and all should be working again.
Any questions, just let us know.

UPDATE: Jan completed the reset and emailed to let us know that it's now working again.

excellent such a great product 29/09/2015
by Su Wimpory

I got my first petporte cat flap 7/8 years ago. It was the best cat flap I have ever used. It did stop 99% of the local cats getting in the 1% that got in either followed my cat or as I saw one of the cats used his claw to pull it open (did take him a while). When I first had it we had 4 cats using it all the time. It moved house with me just over 2 years ago and went in to my new house no problems. I have just bought a new one to replace it and this was only because while some building work was being done the old one got damaged.

Would recommend this to any one who has a cat. Before having this flap I had tried 3/4 different ones but this one is far better than any of them and worth every penny.

> PetSafe Response: Hiya Su, what great feedback on the Petporte, thank you for taking the time to let us know how it's worked wonders for your cats! I hope you enjoy the new one just as much. If you need any support with installation just let us know. Thanks again! :)

Great product 21/09/2015
by Dan Wait

We've had ours for 4 years now, and it has just been priceless for us and our cat (who was being bullied by a neighbour's cat).

One feedback/request I have - would it be possible (if it isn't already implemented, and if so, my apologies) to implement a 'Day' mode so that the cat can only go out at night (to protect fledglings in our garden)?

Thank you.

PETSAFE RESPONSE - we are so pleased to hear how well the Petporte has worked for you and especially fending off the bullies for your cat. We will send your suggestion to our design team in Knoxville as every idea is welcome for future upgrades. Thank you for taking the time to write to us with your idea.

Fabulous! Worth every penny! 16/08/2015
by E M

Keep other cats out. Keep your cat in at night. Keep him in for vet appointments. No magnets to lose. No uncomfort for your cat. Battery backup.
The peace of mind is hard to overstate.
This is rare thing... a brilliant invention.
I recommend this to everyone with a cat.

> PetSafe Response: Hi E M, we really appreciate your feedback and for sharing you story with us. Our Petporte can make a big difference to the security and peace of mind for your pet. Anything you need just let us know :)

Excellent Cat Flap 07/08/2015
by J Geary

Very useful cat flap, so versatile. Ours DOES have a day-night function (see previous review) which we haven't had before, and find a great way to keep our young cat in at night.

The only problem is, we've lost the instruction manual and sometimes have to spend a bit of time working out how to change the settings! Would it be possible to have another copy sent to us?

Many thanks for good product.

> PetSafe Response: Hi J, thank you for taking the time to leave a review for the Petporte Smart Flap® - it's one of our favourite products! We certainly do have the manual available for you: it's on this product page within 'Manuals & Downloads' or you can copy + paste this link:

Anything else we can do to help just let us know.
Thanks again!

Suggestions for improvement 13/07/2015
by Anna Landell

For our cats it works perfectly. However, I have grown tired of the mice, lizards, birds and snakes carried into the house by my cat through the door at night. Would hope for a timer-feature at night.

> PetSafe Response: Thanks for the feedback Anna. I'm sorry to hear you're also finding other creatures being brought in - your cat sounds like quite the hunter!

Very good product 03/03/2015
by Mark Francis

If you need to control / stop other Cats coming into your home. This is your product.

I tried the magnetic cat flap first. But by Cat managed to lose his collar one day and got stuck outside so I quickly upgraded to the microchip reader and never looked back (1.5 years ago)

> PetSafe Response: We’re so happy to hear your pet is enjoying the Petporte Smart Flap product.
We love this product too!

Minor problem 12/01/2015
by David Watson

Cat flap works quite well most of the tine except when our cat enters slowly - The door closes behind him but fails to pass the green peg completely. This allows another cat entry behind. Annoying & making the device a waste of money.

> PetSafe Response: We are sorry to hear you're having a problem with your Petporte. To solve this problem you can extend the lock out time on the door, which allows the door a longer time to close over the lock.
We'll have Customer Care associate email you to resolve your problem.

Great access 06/12/2014
by Philippa archer

Cats use this with ease compared to my petmate, but I found to that to use the timer mode I have to stand in front of the flap at the time of day I want to set it to.

> PetSafe Response: Great feedback Philippa and thanks for your comments. We hope you enjoy your Petporte Cat Flap!

smart pet porte 20/11/2014
by Lee

Fantastic never a problem in about three years of ownership. Cats love it we love it. I'm checking the site out right now for a newer version just to see if they have improved it somehow. Worth every penny, its still going strong.
No other unwanted animal can gain entry. You will kick yourself if you have been using the old fashioned version and they swap to this.

> PetSafe Response: We're so happy to hear you cat is enjoying the Petporte, we love this product too!
Thank you for taking the time to tell us about your experience.
