Every precaution is being taken to maintain this status. Special provisions govern the importation of animals.

Dogs, cats and ferrets from all EU countries except Sweden must have pet passports, ID marking, valid rabies vaccination, and valid blood-test documentation (does not apply to ferrets).  Dogs and cats must also be given approved tapeworm treatment during the week before and the week after importation.

Small rodents, cage birds and rabbits must have valid import permits issued by the Norwegian Food Safety Authority.
