What is a cat flap? A simple explanation of cat flaps!
17. June 2024A cat flap is an opening in a door, usually a front entrance door, that allows a cat to leave and enter the house without someone having to open the door for it. The same concept also exists for dogs, in which case it is naturally referred to as a dog flap.
A cat flap is usually made of plastic or aluminum and is held closed by magnets when not in use by the animal, preventing drafts, heat, or rain from entering the home.
While dog flaps are available in larger sizes because dogs can be quite large, cat flaps are generally small, making it highly unlikely that a burglar could gain access through one.

Cat Flaps Can Be Mechanical or Electronic
Cat flaps are available in both purely mechanical and electronic versions. Both types can be completely deactivated so that they remain closed and neither entry from outside nor exit from inside is possible. Some electronic cat flaps even feature timers, allowing you to specify when your cat is no longer permitted to leave the house because the flap automatically locks.
The disadvantage of a purely mechanical cat flap is that unwanted visitors may enter your home, including other cats and even smaller dogs. If you want to prevent this, you will need an electronic cat flap equipped with a sensor or microchip recognition.
If your cat has been microchipped by a veterinarian, you can pair the electronic cat flap with your pet’s chip. In that case, only your cat—and any other cats or dogs whose chip numbers you have programmed into the flap—will be able to enter the house. Not only households with one or two pets but also animal shelters and rescue centers frequently use such electronic cat flaps with chip recognition. They can authorize access for all of their animals.
If your cat is not microchipped, you can alternatively use a cat flap with a collar sensor. In most cases, the sensor is included with the cat flap. However, in such cases there is always the possibility that your cat may lose the sensor. For this reason, it is advisable to keep spare sensors available or request replacements from the manufacturer if one is lost.
