Lost and Found (all affected areas): A Facebook group called “Hurricane Sandy Lost and Found Pets” is trying to facilitate reunions of pets and their owners by giving people a place to share photos and information. It already has more than 7,200 likes. Many of the pets disappeared when doors or gates blew open in the high winds, or when they slipped out of their collars.
Left-Behind Pets (NY): For New York City evacuees who need to report pets who were left at home during the storm, call the city’s hotline at 347-573-1561.
