A Door Your Cat Opens, Nobody Else's Does

A standard flap lets in whatever pushes it, your cat, the neighbor's cat, or a curious raccoon. Threshold only swings open for a paired RFID collar key, and you decide which direction it opens.

Threshold RFID Cat Door

🔑 Two keys, one remote

2 RFID collar sensor keys and a remote control ship in the box, so more than one pet can have their own key. Each key needs to be paired to the door with the "M" button before it will open the flap.

🔄 4 access modes

Switch between Locked, Out Only, In Only, or open both ways from the door's panel or the paired remote, so you're never stuck walking over to change it.

🤫 Quiet and draft-sealed

The flap unlocks silently, so it won't startle a sleeping or skittish cat, and its sealed design is built to help keep cold drafts from coming through.

🛠️ Installs almost anywhere

A sturdy ABS build fits into wood or plastic doors, walls, or a pet house, built to hold up to daily use by an active cat.

The Worries, Handled

Ready to Use, Quiet, and Flexible

Before installing a smart door, it’s fair to ask if you’ll actually have a working key on day one, whether it’ll startle your cat, how much control you get, and whether it’ll let the cold in. Here’s how each one is handled.

This smart automatic car door is exactly what I was looking for. It's sensitive enough to work with the collar easily and the lock is very sturdy. It was easy to install and after I taught me cat how to use it, he's been using it a lot.

I really like how this pet door comes with 2 collar sensors, now I don't have to worry about a stray animal coming in the house.

The smart pet door comes with a installation diagram to cut the hole exactly what needs cut.

This pet door seems well made and has 4 exit/entry modes. It also comes with a remote so you can control the pet door from a distance. It's a perfect size for all my cats, as some of my cats are pretty big.

This cat door works really reealy well and was pretty easy to install. The collar sensor recognizes my cat quickly and keeps other pets from getting through, which is Exactly what I needed. I also like the different locking options and remote control. It opens smoothly, isn't too loud and gives my cat more freedom without leaving the door open all day. Definitely worth it!!!

Works perfectly! I had to train my shy cat to not be afraid of the tiny beep and lock moving when activated. The other cat had no problem using it. (They were used to their door that opens manually). Very happy with this. No more raccoons coming in uninvited! 🙀

Quality: 10/10 honestly this feels very nice, and despite my cats attempts to scratch up the door, they have been unsuccessful!!!

Magnetic strength: these magnets are pretty strong, you definitely need some force to push the door open, I can see it moving from the wind if the cat was nearby, but otherwise the plastic locks it in place and the magnet is very nice. It did make it a little bit of a learning curve for my cats, cause they didn’t understand that they could push it, but otherwise got it taken care of.

Ease of use: super easy to use on my end, I love the key fob, I kind of wish it came with two but other than that literally no other issues.

Durability: this thing is strong as hell! We use it to separate our two kittens from my older cats since they can be too rambunctious, and my oldest has severe brain damage, which makes it really hard for him to communicate when he is overly stressed out, this has made it so he can escape the bedroom into the other areas of the home where he can relax and remain peaceful, and the two absolute devils are locked inside. We had to place 40 lbs weights in front of my barn door on top of the lock just to keep the boys locked in and there has been no damage to the cat door at all!!!

All in all, this is amazing and I would have left a five stars out of five stars if not for one big issue. If the cats are trying to “exit” the home there is a little ledge that is about 3-4” long on the “outside” of the door. If a cat pushes in to the door when it’s unlocked and then decide that they actually do not want to go outside and they pull their paws back. It will trap their paws, Chinese finger trap style. This got two of my four cats before we decided to only let them use one side of the door. My door is relatively thin, so I might just take my hand, saw and saw off the excess 2” that allows for thicker doors, but until then we only have half of the functionality for the door. A great solution to this might be doing interlocking extenders, that way if your door is really small, it doesn’t do that. If your door is really large though, you will have the same problem. Basically, if your door is too thick, your cats will only be able to exit the house and not be able to enter the house. Or vice versa without risking their little paws. Other than that very quickly, and I love it!!!

Great buy! Easy to install and it works as listed. It’s very stable and secure the quality exceeded my expectations and the size is perfect. I’d highly recommend this to anyone needing to let your cat in/out but worrying about other cats or critters that might be able to get in. I have a very happy cat now.

We installed this in our travel trailer for the cat as we put her food and litter box in the storage area. Occasionally she steps on the button to lock it (so the locking mechanism works great) and can’t get back in so we have to fix it because she keeps banging her head against the door which is super annoying when you are trying to sleep but its really great. It was really easy for her to use and she learned how within a day. Plus keeps the toy doodle out of getting those almond roca’s. Collar works great! Love that it comes with different colors. Easy install and fit perfectly.
