I don't know if you have one close by there we have a clinic that does spay and neuters for low cost of free for rescuers. I is not part of our shelter(kill) We have been given land and mobles to make it and voluter vets. If not mabe you could help these animals by setting up one. we started by having a rotating place mostly the armorys in the area and a lot of the service men and women helped out.
