The cat was found and destroyed by authorities. This is not the first time Icelandic police has to deal with foreign travellers who have smuggled pets into Iceland, and not the first time a cat onboard a RV has been put down. A violent altercation with French cat-smugglers 
 
 In August 2003 police in North Iceland became aware of the fact that a French couple which had arrived in Iceland on the ferry Norröna was hiding a cat in their RV. Read more: Police puts down cat which was smuggled to Iceland on-board RV by foreign travellers 
 
 The officers found the cat, which was taken to the county veterinarian which then put the cat down. An un-declared kitten, puppy, or farm animal could easily introduce a new disease that has never been seen in the animal population before and devastate different animal populations. Under Icelandic law, pets entering Iceland can only do so through Keflavík International Airport, and as well as fulfilling all the standards of the European Pet Passport, must also spend four weeks in quarantine thanks to Iceland’s extremely tough disease prevention laws, which also state that any smuggled animal must be put down and the body destroyed, RÚV reports. The reason for the strict animal laws, Iceland Magazine reported, is that many animal diseases, including rabies, have never been detected in Iceland. On April 24, the Iceland Monitor reported that police in Höfn, South East Iceland, received a tip that a Swiss woman arrived in Norröna on a ferry with her cat in tow. A Swiss woman was arrested in Höfn, southeast Iceland, on Saturday evening for smuggling her cat into Iceland.
– Iceland's beauty attracts more than a million travelers from around the world every year, and a tourist just learned the hard way that the country doesn't mess around when it comes to protecting its turf. A Swiss woman in her 60s entered the country in her camper by ferry and snuck her cat in along with her. Under Icelandic law, pets entering the country can only pass through Keflavík International Airport, must have the proper paperwork, and must be quarantined for a month, reports the Iceland Review. Police acting on a tip arrested the woman in Höfn in southeastern Iceland within two hours of her arrival and promptly brought her cat to a vet, where it was killed. They're also billing the woman for disinfecting her camper van. Some are calling the measure extreme, though Travel and Leisure notes that Iceland has a delicate ecosystem to protect, and that many diseases found in animals all over the world have never been detected in Iceland—including rabies. The argument in favor of the tough measure is that the island's animals could be devastated by just one undeclared animal unwittingly introducing a disease for which the native population has no immunity. Iceland Magazine reports that this isn't the first time a cat has been smuggled onto the island only to be euthanized. In 2003, police put down a French couple's cat they'd hidden in their RV. (There are now about two feral cats per human in Hawaii.)
