Britain’s vote to say farewell to the European Union has put the United Kingdom on sale for foreign visitors, but it's not great news for citizens: Brexit could make it more difficult for Britons to travel abroad.

And it’s not just two-legged travelers that could be affected. British pets from London to Cornwall could be losing a significant perk: the ability to cross borders without extra paperwork or being quarantined.

The New York Times reports that, although it's too soon to say for sure how regulations may be revised, new boundaries could create challenges for pet travel.

Currently, owners of cats, dogs and ferrets can get a passport (a booklet adorned with a portrait of the pet) that documents vaccination and treatment history. As long as animals vaccinated against rabies and are microchipped, they can be jetsetters just like their owners.
