I'm pretty sure you can get an appointment. I was there a couple of weekends ago to pick up my two new kittens. They were simply awesome. My babies came with all vaccination up-to-date, dewormed, spayed/neutered, microchipped, healthy and eating quality food.
THEY ARE OPEN YOU CALL THEM MAKE APPOYMENT
Their website says "The ASPCA Adoption Center in New York City is currently closed for in-person visitors"
