Microchipping cats will become mandatory. The EU has adopted new regulations.
Microchipping cats and registering them in databases will also become mandatory for pet owners. The European Union has adopted a regulation that introduces common rules for identifying dogs and cats and tightens requirements for their breeding, sale, and housing conditions.
The changes will be implemented in stages. The identification and registration requirement will apply to entities and individuals introducing animals to the market from August 31, 2030. For owners of dogs not intended for sale, the deadline is August 31, 2036, and for owners of such cats, August 31, 2041.

Cat microchipping: what will change?
A microchip allows you to link an animal to its identification number and the data stored in the registry. The new regulations are intended to make it easier to determine its origin and the person responsible for it.
Simply implanting a chip isn't enough. Registration in an appropriate database will also be necessary. This identification will not only help locate the owners of lost animals but also curb illegal trade.
For those with cats, the most important thing is the long transition period. The regulation does not require all owners to immediately seek veterinary attention. However, other deadlines are provided for those selling or transferring animals as part of regulated activities.
When will the new rules come into effect?
EU Regulation 2026/1818 entered into force on 30 August 2026. Most of its provisions will apply from 31 August 2028, but later dates are provided for some obligations.
Obligation to chip and register
| Who does it concern? | Since when? |
|---|---|
| Entities and persons introducing dogs or cats to the market | August 31, 2030 |
| Owners of dogs not introduced to the market | August 31, 2036 |
| Owners of cats not introduced to the market | August 31, 2041 |
These deadlines are based on the new EU regulation. They do not replace obligations that already exist in national law.
2041, therefore, does not mark the end of animal protection or the effective date of the entire regulation. It is the date on which the identification and registration obligation will begin to apply to a specific group of cat owners.
Better conditions in breeding farms and shelters
The new requirements apply to breeders, sellers, and shelters, among others. Animals must receive adequate food and water and be housed in a safe environment with adequate temperature, ventilation, and space.
For cats, the regulations also provide hiding places, raised areas, and scratching posts. These are conditions that allow the animals to move, rest, and behave in a manner natural to their species.
The keeping of animals in spaces that prevent normal movement will be restricted. Exceptions are made for specific, temporary needs, such as examination or treatment.
The regulation also prohibits painful procedures performed without medical indications, including ear and tail docking and declawing. However, a special provision is provided for feral cats.
A notched ear may indicate a spayed cat
Member States will be able to allow sterilized cats to be marked by a small incision or removal of a fragment of the ear tip. This applies to trapping, neutering, and re-releasing programs.
This marking helps identify a cat that has already undergone the procedure and avoids re-catching it. This is especially important when caring for large cat colonies.
Stricter rules for animal reproduction
Regulations restrict the breeding of closely related animals and the crossing of domestic dogs and cats with wild species to produce hybrids.
Cat breeding also has minimum breeding ages, litter size limits, and required rest periods. A female cat cannot be used for breeding again after two cesarean sections.
The new framework aims to curb practices where the number of animals sold is more important than their health.
The registry will not solve the problem of homeless cats
In the statements quoted by Philenews, Charalambos Theopemptou emphasizes that animal identification must be linked to a broader policy of their protection.
Sterilization, care for feral cats, and cooperation between authorities, local governments, and volunteers remain essential. A chip allows for the identification of an animal, but it does not limit the number of subsequent litters or provide it with a home.
Member States are also expected to establish effective and dissuasive sanctions for violations. Specific national measures will therefore be an important part of implementing the new rules.
