Pros: No collar keys required, keyed locking design for up to 32 cats, hard plastic door, good seal

Cons: Cats are required to be microchipped


The SureFlap Microchip Cat Flap is a clever design that offers a keyed access for your cat by detecting the unique code from a microchip. This eliminates the need for a special collar key and saves cost if your pets are already microchipped.

Microchipping has been around for years to help identify and return lost pets. The cost to 'chip' your pet is low and easy to do at any veterinarians office or shelter. Each chip has a unique code and is read by an RFID scanner. Should your pet be turned into a shelter, the chip can be scanned and the id number is linked to a record that identifies the owner and contact information.

SureFlap uses this existing microchip technology as the key to unlocking the pet door. A single button is used to record the id of each of your cats. Any cats that have not been recorded, even if they have been microchipped, will not unlock the door. The electric lock only works in one direction (coming in from the outside) and the pet has free access to go out anytime. The door also includes a mechanical lock can be set to only allow incoming, outgoing or no access (fully locked).

Currently only one door size is available. The door is made of clear hard-plastic and is expected to hold up well. The opening is on the small side, so it may not work if you have a huge cat, but shouldn't be a problem for most cats.

The SureFlap Cat Flap can be installed in all types of doors and walls up to 2 3/4" thick. Optional tunnel modules adds 2" per module to extend to any length. While installation in a metal door should work in most cases, it may be necessary to use a slightly larger hole and optional adapter as the metal can reduce the detection distance for the microchip. An optional adapter is also available to install in a glass door. Keep in mind that safety glass, typically found in patio doors, cannot be cut without breaking. It can also be installed in dual pane glass, but special glass fabrication will be necessary.

Because the door does not automatically lock in the outgoing direction, small raccoons might be able to lift the door up from the outside and crawl in as commonly occurs with other door designs we've tested. The small opening and tunnel design helps reduce the chances of raccoons using this trick. Customers of SureFlap have reported that it has successfully stopped raccoon entry for them.

The unit runs on a 4 AA cells and is expected to run for 6-12 months. A low battery indicator flashes once every 5 seconds when the battery is nearing the end of life. The memory for recorded microchips is retained even without battery power.

We highly recommend this door, especially for its' clever collarless key approach and overall quality design.
