They do offer spade and whatever else for rescues and as far as I know they are the cheapest around
I know they are lower cost than other area Vets' hospitals but I don't know if they offer services for rescues. Islip's Animal Control on Sunrise Hwy in Bay Shore used to charge a very low fee for feral cats. You might want to try them.
Island rescue should be able to help, plz call them and tell them the situation.
