Cat Mate 4 Way Locking Large Cat / Small Dog Door

Very good pet passageway
Very good pet door that is installed in a metal porch door. This is the third cat door I’ve purchased and replaced over the past three years. Initial installation was no major problem if you are comfortable with removing the door and cutting the opening. The only issue I’ve encountered is the locking latches. Over a period of time they become weak from twice daily use and as a result my cats have at times locked themselves in or out by inadvertent movement of the latch tabs. Otherwise the pet door is well built and quite serviceable.

good quality, not difficult to install
This is not a 5-star review because the original order did not arrive as scheduled, apparently lost somewhere in transit by the USPS. And there were a few problems with the door itself, noted below. It is a 4-star review because, when I contacted Seacorals to report that I still had not received the shipment several days after it was supposed to arrive (and was not able to find out anything about its current whereabouts using the tracking number supplied by the USPS), they promptly sent me a new door and expressed considerable concern over the shipping failure. Also, the problems with the door did not prove to be serious.
The cat door itself appears to be of good quality, and is not difficult to install, though installation in a 1.75 inch thick solid-core door between our house and garage presented some challenges.
First, the liner that fits inside the cut-out is not nearly long enough to cover the entire thickness of a door this wide, leaving an unappealing brown strip visible through the middle of the opening. I solved that problem simply by lining the cut-out with white plastic duct tape. This matched the white paint of the door and the white plastic of the cat door liner closely enough to be unnoticeable, at least to a casual inspection.
Second, although the cat door apparently is supposed to assemble using 8 short #6 screws to independently attach each side of the frame to opposite sides of the door (4 screws per side), I didn’t like this “non-aligning” assembly feature. So I decided to get 4 long screws to “self-align” the two sides, cinching them together by passing the screws through the room door around the cut-out. For my 1.75″ door, my first guess was that 2.0″ #6 screws (the longest #6 screws I could find at the local hardware), would do the trick, but these proved a bit too short to go through the door when widened by the 2 frames on each side of it. I then moved on to 2.5″ #8 screws, which were long enough. The extra thickness of the #8 screws was not a problem (I just drilled the pilot holes through the door a little bigger). So that was all good.
The installation bonus was that, to position the cat door low enough for the cats to use, I had to install it across 2 raised panels of the room door. This meant there was a “V”-shaped depression in the middle of the opening on each side that, when I first cut it, I thought I would have to fill in with some type of sealer under the frames, to make the opening air-tight. However, when the frames were fitted to the opening–although the inside liner was not long enough to reach all the way through the door–it did prove long enough to completely cover these depressions, providing a good tight fitting seal all the way around the opening on each side, with no additional effort. (If you don’t want to settle for the pretty good natural seal provided by the frame liners, you could easily caulk around the outside of the frames to ensure a perfect seal.)
As for the cat door itself, once installed, it seems perfectly functional. Although our 2 cats are both still kittens, the door appears to be the perfect “Goldilocks” size — not too big, but not too small either for an adult cat, just right. Due to the magnetic closure feature, the flap operation of this door is stiffer than the free-swinging flaps I’ve had in the past — the flap stops abruptly in the down position and has to be “broken” free when opened — but that fact didn’t seem to bother either kitten, both of whom learned to pass through it freely in less than a day.
The 4-way closure feature is logically complete, covering all possibilities (which I appreciate abstractly, as a former teacher of logic), though we only need 3 of the 4 settings. (Open both ways, so the cats can pass back and forth at will; open out only, so the cats can’t come back in the house when they are banished to the garage for some reason, e.g., cat-allergic guests; & open in only, so the cats can’t go out into the garage when some activity is in process better done without a curious cat in attendance, e.g., working with power tools. I guess the fourth setting, open neither way, might be useful if you had two incompatible sets of animals needing temporary separation.)
My only small concern is the plastic locking tab has to be pushed up to slide it back and forth, and I don’t know how durable this plastic tab will prove to be over time in daily use (I’ve had a lot of plastic tabs break off over the years). But, so far, so good.

This cat door works perfectly. The extenders make installing it in different thickneses of wall a brezze. I moved it from one house to another and the quality keeps it looking great even afterr a move.

Buen empaquetado, muy fácil la instalación, buen acabado, funcionamiento correcto, cumple con todas las expectativas
