PetSafe (formerly Staywell 400) Magnetic Cat Flap

The PetSafe (formerly Staywell 400) Magnetic 4-Way Cat Door - White

(formerly the Staywell 400 Magnetic Cat Flap) provides security against intrusion by strays without requiring batteries or house current! The secret? The collar key itself is a stronger magnet that actually unlocks the flap allowing access by your pet but not by other pets or strays.

As the flap dimension is relatively large for a 'cat' sized door, PetSafe feels it to be suitable for cats up to 15 lbs. You should make your own test by simulating the opening and calling your cat through with a treat.

This cat flap is self-framing from 0" to 2 1/4". tunnel sections may be added one at a time as needed for installation in a wall. Because it's self-framing, it may be installed in any door including solid or hollow core, metal (aluminum or other non-magnetic material), insulation filled etc.

It should not be installed in a door made from steel or other magnetic material.

Hot Tip Take any magnet and see if it's attracted to the door you intend to use. If it is, the door is magnetic.

Reversed installation (turning the pet door around so that it controls from the inside rather than from the outside) will void the warranty.

Important installation point These PetSafe Magnetic cat flaps should be installed high enough so that the collar key actually touches the tunnel when the cat approaches. If not mounted high enough for this to happen, the door may not respond.

We would not recommend this door for dogs due to the requirement that the key actually touch the sensor.

A 4-way lock is also included which has been significantly improved over the original design.
