What is a microchip?

Cat microchipping is a tiny computer chip that's installed, about the size of a grain of rice, implanted under your cat's skin. Each microchip contains a unique serial number, which is registered in a database along with the cat owner's contact details. This microchip implant increases the likelihood of reuniting owners with their lost or stolen pet cats. Under new rules, cat owners in England need to register their microchipped cats' identification numbers and contact information to avoid fines. Starting June, it becomes a legal requirement to microchip cats by the age of 12 weeks, improving animal welfare and aiding rescue centres in identifying stray pets. Whether you have an indoor cat or one that uses a cat flap, microchipping is essential to ensure your pet's safety.

What is the new cat law in 2024? Is microchipping compulsory?

Under the new law in England, all pet cats must be microchipped by the time they reach 20 weeks of age, with the exception of unowned cats like feral and community cats. This requirement includes indoor cats, which must also be microchipped. The microchip implant contains a unique serial number that must be registered with a Defra approved database, including up to date contact information for the owner.


As of 10 June 2024, it is a legal requirement for all pet cats to be microchipped. If you fail to have your cat microchipped within 21 days after this date, you may face a fine of up to £500. The microchip helps increase the likelihood of reuniting owners with their lost or stolen pets by providing a unique identification number.


Although this law is currently enforced only in England, we are advocating for similar regulations in Wales, Scotland, and Northern Ireland. To ensure the welfare of your cat and facilitate their return to you in case they stray or get stolen, we recommend that all cat owners get their pets microchipped. This is crucial whether your cat uses a cat flap or is solely an indoor cat.

A small microchip is implanted under your cat's skin, giving them a unique code. If your cat is found away from home and taken to a vet, their microchip can be scanned electronically.

This information must be up to date as of June, as part of the new cat microchipping law in England. The microchip ensures that if your cat goes missing, the keeper can easily access and update your details to help reunite you with your pet.

Will microchipping harm my cat?

Microchipping your cat is a swift process and no more painful than an injection. There’s no need for recovery, and the procedure won’t cause your cat any discomfort.

As part of the new cat microchipping law in England, keeping your contact details up to date in the pet database ensures that the unique microchip number can be linked to you, the owner, if needed.

Can a cat's body reject a microchip?

Microchips are engineered to be fully accepted by the body without rejection. The information unit within the microchip is encased in robust, medical grade glass, ensuring durability and minimal reaction. This material can withstand the physical activities of your cat, so whether they’re exploring, playing, jumping, or resting, the microchip remains unaffected.

Occasionally, some cats might experience minor swelling at the injection site, but this generally resolves on its own within a few days. As required by the new law in England, if you have any concerns about your cat after the microchip insertion, it’s best to contact your vet. Ensuring that your contact details are up to date in the pet database associated with the microchip number is essential for the keeper.
