Cat Flaps & Doors
Microchip flaps, locking flaps, wall and window doors and interior pass-throughs, compared on who they let in, power and mounting.
A standard flap lets any animal through; a microchip flap opens only for registered cats, keeping out neighbors' cats and wildlife. Some microchip flaps also scan on the way out, so you can keep specific cats indoors.
Fit is physical: measure your cat's widest point and the door or wall thickness, and check the cut-out size on the template. Interior pass-throughs let cats reach a litter room behind a closed door.
What decides it
Who gets in
Microchip or ID-disc flaps for selective entry; standard flaps for single-cat homes without intruders.
Size
Measure your cat and compare it with the flap opening, not the outer frame.
Mounting
Doors, walls, glass and windows need different kits; thick walls need liners.
Power
Microchip flaps run on batteries; app models also need a hub.
