This Electromagnetic pet door is designed to selectively admit only pets wearing a collar carrying a special magnet. Normally the flap is prevented from opening into the house by an electromagnetic catch, thus preventing stray pets from entering your house. However, when your pet approaches wearing the magnet, a detector located in the outer edge of the body molding senses the magnet and the electromagnetic catch is automatically depressed. Your pet may then push open the flap with its nose to enter the house. As soon as your pet has passed through the flap the electromagnetic catch returns to its normal position, so that following pets without a magnet are prevented from entering. Pets may exit from the flap without wearing a magnet.

Now you can ensure that stray pets will not enter your house! Your cat simply wears a magnet attached to its collar which is identified by a sensitive, fast reacting electromagnetic circuit suitable for cats of all temperament. A 4-way locking system ensures complete control of your cat's movements into and out of your house. Built to the highest quality standards with your cat's comfort in mind, cat friendly features include a silent action transparent flap and a unique step designed to help your cat enter from outside. This neatly designed door is suitable for cats up to a 14" shoulder height. Requires one 9V battery (which will provide on average a 12 month life). This door is guaranteed to keep out cats and dogs without magnets on their collars.
