Benefits Of Having A Cat Flap?

Having a pet door allows your pet to freely come in and out of your house, for pets such as cats, this is really benefited. Cats are slightly more independent than dogs, they enjoy being outside as they are able to roam their “territories” and exercise as they wish, reducing boredom and stress. Cats are very prone to obesity and diabetes if they do not get enough daily exercise. In dogs, a pet flap can help improve toilet accidents; especially in puppies and older dogs also for if you need to leave your dog for extended periods of time.



This is the most basic type of cat flap and opens when your cat pushes against it. This type of flap offers access to all cats that try to use it. This can make it difficult to stop other cats from coming in to the home.


This type of cat flap is operated via a magnet or infrared device attached to your cat's collar. When the collar is within reading distance of the cat flap, the device will unlock the flap, allowing your cat access.


This type of cat flap is operated by your cat's microchip and is also suitable for multi-cat homes as, once programmed, can remember several different microchips. These cat flaps are the best method of preventing other cats from entering your home.
