After the marking, which is done by a veterinarian, they must also be registered with the Swedish Board of Agriculture - something that has long been done for dogs.
- Most people have wanted an ID mark in the past, but the small percentage who don't have one don't have a choice now.
We are very busy, says Lina Johansson, veterinary assistant at the small animal clinic Fyra Ben in Karlskrona.
"Take cats seriously"
Either a small chip can be surgically inserted at the back of the cat's neck, or it can be earmarked with a tattoo.
Sofie Abbereus is a veterinary nurse at Karlskrona Veterinary Clinic.
She is also on the board of the cat association SVERAK and has long wanted a law, similar to the one for dogs, to apply to cats as well.
- The law is a way for authorities to take cats seriously and see that they are a family member like the dog.
It raises the cat's status, she says.
Already at the turn of the year, the ID marking must be ready.
On the second day of the year, January 2, registration at the Swedish Agricultural Agency opens.
If you do not register your cat, the county administrative board can decide on an injunction, which can be combined with a certain amount of money, a so-called fine.
