Your animal in, the neighbor’s cat out · review
A microchip cat door with programmable timer locking, reading the cat’s existing chip and letting any cat out.
What we take from it A hundred dollars against two hundred and ten for the SureFlap doors, and it reads the chip your cat already has. What it buys at that price is entry-only selectivity and a four-way timer; what it does not buy is a published chip-standard list.
A microchip cat door with a four-way timer, overall 9¾ × 10⅜ inches, cut-out 7¹⁄₁₆ × 8¹⁄₁₆ inches, battery powered. $99.99 — less than half what the SureFlap doors on this shelf cost.
SureFlap’s three doors sit between $209.89 and $227.94. PetSafe’s two at $200.99 and $269.99. This is $99.99.
What the money does not buy is the thing the shelf cares about most: which chip standards it reads. The listing says “reads your cat’s existing microchip” and leaves it there. The two SureFlap Pet Doors on this shelf name all three — 9-digit Avid Secure, 10-digit FDXA, 15-digit FDXB — so a cat with an older chip can be checked before ordering rather than after.
“Allows all cats to exit freely while only permitting microchip-recognized cats to enter.”
That solves the neighbor’s cat and leaves your own cat free to go out. It does not let you keep one cat in while another goes out — for that the SureFlap DualScan on this shelf reads in both directions, at twice the price.
Four-way timer-controlled locking, programmable, so the door can be set to lock at night and open in the morning without a phone, a hub or a subscription.
The PetSafe SmartDoor on this shelf does the same thing through an app at $269.99. A timer cannot be changed from the office; it also cannot stop working because a firmware update went wrong.
Overall 248 × 265 mm (9.76 × 10.4 in), cut-out 178 × 204 mm (7.01 × 8.03 in), or a 232 mm (9.13 in) circular hole. Three figures, all published — which is more than most of this shelf gives, and they are the ones that decide whether the door fits the panel you have.
The chip standards, the battery type and count, the battery life, and the number of cats it stores — “stores multiple microchip IDs” is as precise as the page gets.

The listing does not say which standards it accepts, which is the one check the shelf asks you to make. A 15-digit FDX-B number is the modern standard and works with every door here; a 9 or 10-digit number is older and only some models accept it. The two SureFlap Pet Doors on this shelf publish all three standards by name. If your cat’s number is 15 digits, the risk is small; if it is shorter, ask before ordering.
No. It is entry only: any cat can leave, and only recognized chips can come back in. To control exits per cat you need a door that scans in both directions — on this shelf that is the SureFlap DualScan at $209.89, which sets exit permissions individually for up to 32 cats.
It locks and unlocks the door on a schedule, in four modes: in and out, in only, out only, and fully locked. Set it to hold the cat indoors overnight and release in the morning. The PetSafe SmartDoor here does the same through a phone app at $269.99 — the timer is the version that keeps working when the internet does not.
