After losing their homes to Hurricane Sandy, there are nearly 40,000 New Yorkers competing for new places to live. For many, it’s meant moving from friends’ homes to hotels to relatives’ apartments. It’s a constant journey of transition that’s tough on people, but even harder for pets who don’t understand why they can’t settle into a home. To help provide a more stable living situation for four-legged friends, the A.S.P.C.A. has opened a gigantic pet shelter in Brooklyn that will house up to 700 dogs, cats and even a few more exotic animals like ferrets while their owners seek out more permanent lodgings. The first 30 days are free thanks to generous grants from people like celebrity human and pet chef, Rachel Ray.
