PetSafe Magnetic Cat Door.

The PetSafe 4-Way Magnetic Locking Cat Flap provides your cat or smal dog with the freedom to enter and exit the house as she pleases. It also keeps stray pets and critters out with a magnet that communicates with the door itself. In addition, the 4-way locking mechanism allows you to allow your cat in only, out only, in or out, or locked entirely.

The Magnetic Cat flap does not require elctricity. You do not have to charge batteries, or plug any devices in for it to function. This also means that if your power should go out, your cat door will still work.

The 480US Additional Magnetic Key Pack allows you to provide access to multiple pets, so they can both have the freedom that they crave!

Note: The Staywell 4 Way Magnetic Locking Cat Flap will not work on magnetic doors, such as those that are made of steel. To find out if your door is magnetic, simply take a regular magnet and if it attracted to the door, then the door is magnetic.
