Picture of a cat flap

Looking for the best cat flap for your furry friend? It’s a great investment for any cat owner, allowing your pet to easily come and go from your home without needing you to open the door. Yet, finding the right cat flap is not always easy. There are a lot of products to choose from and you may have unique requirements for your pet, which is why it helps to do some research before buying so you know exactly what you need. To help you find the best cat flaps, check out the buying guide below.

What are cat flaps?

A cat flap is a small opening that lets cats enter and exit a property without opening a door. Original cat flaps were simply small holes cut into a door but modern products are far more sophisticated, such as cat flaps controlled by the cat’s microchip to prevent strays from entering.

Why should you buy a good cat flap?

If your cat is allowed outdoors then the best cat flap is highly recommended. It allows you to provide around-the-clock access to the garden and the outside world without needing to open and close the door yourself. This is especially useful if you are out at work but don’t want to leave the cat stuck inside or outside, with a cat flap allowing coming and going as it pleases.

Choosing the best cat door can be challenging if you are unsure of what you need, so here are some things to consider when buying:

  • Opening Mechanism: Cat doors come with various opening mechanisms, so be sure to consider what is best for your needs. For example, manual flaps are basic, featuring a hinged opening that the cat pushes against to open, so while cheap it does not prevent other cats from entering. Magnetic and chipped cat flaps provide controlled access, either via a magnet on the cat’s collar or their microchip, being more expensive but ensuring no unwanted visitors use the opening.
  • Features: While a basic cat flap does not come with any features beyond opening and closing, some products come with additional functions you may find useful. For example, a microchip cat flap may have programable timers that lock and unlock during the programmed time frames. Many allow you to apply settings for several cats, which can be handy for restricting access if one needs to remain indoors after a visit to the vet, while there are even cat flaps that come with compatible apps for controlling the settings remotely.
  • Size: There is no standard size for cat flaps. So you need to check what size of the opening you require. If your cat is normal sized then a standard cat flap size should work fine, although you may need to go for something larger if you have a big cat. Also, larger-sized cat flaps can be used for small-sized dogs.

What is the best kind of cat flap in the UK?

There are a few popular types of cat flaps available to buy:

  • Manual Cat Flaps: The most basic type of cat flap, these are opened by the cat itself pushing against the flap. You can control access with this type of cat flap, beyond locking it, so you may get unwanted cats and other animals using it.
  • Magnetic Cat Flaps: This type of cat flap is opened via a magnetic lock, with a magnet attached to the cat’s collar unlocking it as it pushes through, helping to prevent strays and other cats from entering.
  • Microchip Cat Flaps: The best cat flap in terms of functionality, it features a sensor that uses the cat’s microchips to grant access. You can use this to control access for many cats, making it a great choice for a multi-cat household. Of course, it also prevents other cats from entering.
