Do you have a cat or are you thinking about getting one? Then you’ve probably heard about microchipping cats. But what exactly does it entail? And why is it so important? In Belgium, you increasingly hear that it’s mandatory, but is that really the case everywhere? In this blog post, we’ll explain everything you need to know about microchipping your cat – clear, concise, and helpful for every cat lover.
Meaning of chipping a cat
Microchipping a cat involves inserting a small electronic chip under your cat’s skin, usually between the shoulder blades. This chip is about the size of a grain of rice and is virtually painless. The chip contains a unique number. This number is registered in a central database, along with your name, address, and contact information. If your cat ever gets lost or wanders off, a veterinarian or shelter can read the chip and quickly locate you. The chip itself doesn’t contain GPS or a battery. It only works when read by someone with a special scanner. Therefore, microchipping helps bring your cat back home safely.
Why get my cat chipped?
Microchipping your cat is important, even if they usually stay indoors. Cats are curious and can still escape or get lost. Without a chip, it’s much harder to find your cat. With a chip, a vet or shelter can immediately find your contact information and call you. This way, your cat gets home faster and safer. A chip is also useful in the event of an accident: emergency responders immediately know who the owner is. A collar can become loose or lost, but a chip always stays in place. Microchipping is a small effort that prevents many problems. It’s a smart choice for every cat owner who cares about their pet’s safety.

Is it mandatory to have my cat chipped in Belgium?
Yes, microchipping cats is mandatory in Belgium. Since November 1, 2017, all kittens born before 12 weeks of age must be microchipped and registered in the CatID database. This also applies if you’re not selling or giving away the cat. If you’re changing owners, the microchip must be up-to-date first. Cats born before 2017 and never changed owners are exempt, but microchipping remains recommended for them as well. Without a microchip, it’s difficult to find your cat if it goes missing. Note: the microchip number must always be linked to your current contact information. This way, you comply with the law and protect your cat smartly.
