SureFlapMicrochip Pet Door Tunnel Extender (White)

Unfortunately it wasn't what I wanted in the end. Easy installation in wall with sleeve (sold separately). It responded to my dog's microchip so no collar or key was needed (2 keys are supplied). Great styling & performance. It has 4 functions: a two-way in & out so door opens freely both ways (no programming needed); There is In Open; There is Out Open; There is two-way Fully Locked.The problem is: once the programmed pet goes out, its locked out. Once the pet comes in, its locked in. The two-way open feature allows all kritters in & out. The programmed pet will have to be manually let in or out by the owner depending on the setting. That kind of defeated the purpose of having a pet-operated security door.

This tunnel extender description page clearly states it is the PET DOOR tunnel extender, not the cat door tunnel extender. But when I received the two of them I ordered, they were the CAT door tunnel extender, not the pet door extender. I paid for the more expensive pet door extender. The item number on the page is for the correct item, so my deduction is that Amazon warehouse has this item in the wrong bin. My husband worked for Amazon and says it's about impossible to pick out the wrong item because each item is scanned as you take it out, and the bins are all bar coded. So I don't think a robot or person reached into the wrong bin, because when the items were scanned they would be flagged as the wrong items. Since they were shipped with no problem, the bins must be stocked incorrectly. The customer service rep told me to reorder the same items and he didn't think the same mistake would occur again, but I'm not risking it. I got a refund from Amazon.BUT, the SureFlap pet door ROCKS. Love it, love it, love it. I have a cat, but I bought the larger pet door, because I thought she might be too skittish to go through the smaller door. Glad I did. I saw a video of a cat unlocking the CAT flap, because there's only one lock button on the cat door, so the cat could push the button with one paw and pull the flap open with the other paw. The pet door has two lock buttons, so an animal would have to press down both buttons and pull the flap at the same time. Unless you have two cats who can reason and coordinate, your cat won't get out when this door is locked. The extenders are necessary for most walls. If you put this flap in a door, you likely won't need the extenders. Best thing ever. Only drawback is we have occasionally had birds or mice in the house when the kitty brings us her treats before they are dead. You could solve this by putting the door into an enclosed porch and not the main house. But, I just live with it. A cat is worth chasing a few critters. :-)

This tunnel extender may work very well, but I am giving it one star, as it is so easy to order the wrong size from the Amazon.com website. The website offers two SureFlap microchip cat doors - one white and one brown. It also offers tunnel extenders in white and brown. I ordered a brown cat door and a brown tunnel extender, not realising that the brown tunnel extender is NOT the right size for the cat door. It is intended for the SureFlap microchip PET door, which is larger than the cat door. This is not made at all clear on the Amazon website. As far as I can see, Amazon offers a brown tunnel extender only for the 'pet' door and a white tunnel extender only for the 'cat' door. Be very careful when ordering!

I used this extender with the petsafe chip reader pet door which is installed in the wall of my house. I should have bought 2.

Feels flimsy. Needs to be held together with duck tape but proper use of gorilla glue works great too. Make sure to order enough for thickness of wall. I had to use three to account for 1/2 inch drywall, 5 1/2 inch studs and 1 1/4 inch stucco. Once in, they look better than a wood frame.

We purchased the 11.1 x 10.3 x 0.4 inches size. I believe that it is only good for small to medium size dogs. If your dog is bigger than 35-40 pounds you may need to see if they make a larger size or purchase a different product.This pet door has worked great! We have an 11 y/o Chihuahua and he loves the independence of being able to go play outside while we are at work. It certainly has allowed us to go to see a movie and/or socialize without worrying about whether the dog needs to be let outside. Programming it to only open for his chip has also given us peace of mind that no other "critters" will get into the house!I have actually purchased two of them. We liked it so much that when we bought our new home we bought another SureFlap, and left the original in the door of the old house, for the new owners dog. He has told us that it works great for his dog too.

These fit the SureFlap Pet door perfectly for installing in a wall. It took two to go through our wall. I wish there was a way to connect them without using duct tape. However, the cats love their escape hatch from the house to their outdoor condo on our covered upstairs patio. The dark picture was taken inside. The second picture shows the extenders outside looking through the connector my husband built from the house wall into the cage. Besides the cats loving being outside, keeping the litter box outside is a huge plus. We water them outside, but feeding them outside did not work because we had raccoons visit our patio. They could not get inside the pen, but they tried reaching as far as possible to get to the food.

Bon produit, un peu cher mais bien.

Passt perfekt

Sehr gute Erweiterung!Ich habe sie trotzdem wieder zurück geschickt, da meine Klappe dann doch noch grade so in die dicke Tür gepasst hat und ich die Tunnelerweiterung nicht brauchte.Hier wären genauere Maßzeichnungen für Klappe und Tunnel hilfreich, das würde Kunde und Lieferant unnötige Wege und Kosten ersparen!

Ordered the cat flap, the tunnels (4) and the monitor device. All from the same supplier and the tunnels are for a different model. On Amazon they were linked products. Now have the hassle of trying to contact the seller, maybe my stupidity but in the app there is no contact seller button once the goods have been delivered, so this resulted in a review instead.

Ho comprato queste estensioni per il mio Sure Flap Pet Porta dopo aver fatto diverse ricerche online. Il Pet Porta l'ho comprato su un altro sito perché su amazon non trovavo Il PetPorta connect. Si adatta perfettamente. Bisogna prendere bene le misure in modo tale da non ordinarle troppe. Io ne ho preso 3 ed è stato sufficiente. In verità per non sbagliare ho aspettato di montare prima la porta per poter valutare bene lo spazio del tunnel nel muro. Mi raccomando queste estensioni sono solo per Petdoor, se avete il Catdoor le estensioni sono diverse. Vi consiglio comunque di consultare bene il sito della Sureflap dove ci sono tutti i tutorial e video di cosa serve e come montarle. Spedizione Velocissimo Grazie Amazon.
