In this article, we will explore what makes a quality microchip cat flap, highlight some top features to consider, and review leading products to help you make an informed decision.
Understanding Microchip Cat Flaps
A microchip cat flap is a specialised cat flap that reads your cat’s existing microchip to grant access. Unlike traditional cat flaps, microchip catflaps restrict entry to only the cats whose microchips have been programmed into the flap’s system. Your cat needs to be microchipped in order to use a microchipped catflap.
This cutting-edge technology helps keep your home secure from intruding animals and reduces the risk of your cat getting into unwanted fights or dangers outside. It also prevents other neighbourhood cats from sneaking in and disturbing your space.
Key Features of the Best Microchipped Catflaps
When searching for the perfect microchipped cat flap, it’s a good idea to consider the following essential features:
1. Compatibility with Your Cat’s Microchip
Ensure that the cat flap is compatible with your cat’s microchip type. Most microchip catflaps work with ISO standard 134.2 kHz microchips, which are common in the UK. Verify compatibility, especially if your cat has a different microchip frequency or you plan to add more cats in future.
2. Programmable Access
The best microchipped cat flaps allow you to program multiple microchips, up to 32 identities —ideal for households with several cats. Some models let you easily add or remove access through straightforward programming options.
3. Battery Life and Power Source
Look for cat flaps that have reliable battery life, as many operate on batteries rather than mains electricity. Some units offer low-battery alerts or the option for an AC adapter to avoid frequent replacements however bear in mind if you opt for an ac you will have to locate the cat flap near a plug socket.
4. Durable Build and Weatherproofing
As the cat flap will be exposed to outdoor elements, it should be robust and weatherproof. Materials like tough plastic or metal frames and sealed electronic compartments help ensure longevity.
5. Locking Modes and Manual Override
All cat flaps have different locking modes—fully locked, fully unlocked, opening in only, opening out only and microchip-only access—can be very practical. A manual override is useful if your cat needs restricted access for a period.
6. Size and Installation Flexibility
Choosing a cat flap with suitable dimensions for your cat is essential. Many high-quality microchipped cat flaps come in various sizes. When installing cat flaps into glass it is essential you do you research to make sure the cat flap is suitable for your cats size. Once the hole is cut into glass it is then sent off for toughening to help strengthen the glass, after this process the glass cannot be recut so this could be a costly mistake to make.
