In February, a red fox was rescued after an unusual journey across the pond. Believed to be about 2 years old, the young male was discovered as a stowaway aboard a ship traveling from Southampton, England, to the Port of New York and New Jersey. After being transported to the Wildlife Conservation Society’s Bronx Zoo, the fox was treated for a potentially fatal parasite — and last Friday, he was declared healthy. Now known as Basil, the fox was initially diagnosed with Angiostrongylus vasorum, or French heartworm: a parasite typically seen in foxes and other wild canids in Europe that can lead to respiratory disease and death if left unmanaged. Thanks to the zoo’s veterinarians, Basil underwent a monthlong treatment plan that cleared the infection and resulted in him gaining weight and developing a fuller coat. He’s also completed quarantine, and while he remains at the zoo for the time being, officials are evaluating options for his long-term placement. Craig Piper, the zoo’s interim director, told The New York Times that Basil is doing well, noting that he’s “very bright” and “curious” — uncommon traits for foxes, which are often aloof. He said in a press release: “Treating wildlife like this requires extensive coordination and expertise from our veterinary and animal care teams. We are very pleased with his recovery and continued progress since his long journey across the Atlantic.”
