Electronic Pet Doors for Installation in Walls
This is the home page for all electronic dog doors and cat doors designed for installation in a wall.
When installing a pet door in a wall, the wall must always be 'framed out'. That is, after cutting the hole, the inside of the wall must be sealed off so that moisture cannot penetrate into the interior of the wall. The 'self-framing' pet doors and wall kits listed here will help to do this step for you and make the job much easier.
However, if you can Frame the Wall Yourself, you can choose any pet door for a wall. For example, if you wanted a Catwalk Magnetic Cat Flap in your wall, you'd have to frame it yourself as there is no wall kit for that door.
Because electronic pet doors have rigid flaps, it's usually not necessary to have a separate locking cover. First, when used in active mode (some can be used passively which is helpful for training), the pet door is locked at least from the outside. The smaller 'cat flaps' generally have a 2-way or 4-way lock built-in to the cat door.
Important Don't confuse these with self-framing electronic pet doors for doors! The adjustment range for a self-framing wall mount must be much greater then for a door mount.
A double flap pet door (a flap on both sides of the wall) is usually a good idea. The 'dead' air space between them will serve as better insulation than a single flap will. However, this gets a bit problematic when you're thinking about an electronic pet door. First of all, there is no such thing today as a 'double flap' electronic pet door. Secondly, if you try to combine two electronic pet doors (or even two manual pet doors with rigid flaps) you've got to keep those flaps separated so they don't interfere with each other. The leverage is all wrong. Plus you can't allow the doors to get wet. The best you can do is to select an electronic pet door that has some thickness in the flap which will help the insulation problem.
In choosing the size, keep in mind that your pets will be negotiating a short tunnel. For that reason, we like to see a little more clearance vertically than would be the case for a pet door installed in a door. As always, try to mount the pet door so the top of the flap is at least as tall as the top of the tallest pets shoulder.
Vital Notes Regarding Installation of Pet Doors in a Wall
It is imperative to remember that even a self-framing pet door must be properly installed and caulked to ensure that no moisture enters your walls. If you have any doubt regarding your ability to do this, please assign the job to a qualified person.
Likewise, cutting a power line or hitting a pipe with power tools could cause injury or even death. If you are not sure you have the skills to tackle this kind of job, please have a qualified person do it for you.
Generally, you can be confident that a properly licensed and insured contractor will have the necessary skills.
