In a way it does save lives by preventing unwanted lives from coming into being in the first place. If the only place to get a kitten or a cat is from a shelter or from breeders who only breed when there is enough demand for kittens, then eventually shelters will no longer be as needed and all may be able to become no kill. Cats will no longer be put down by the millions because the only ones born will be ones bred when people want them.Really, I thought spaying and neutering was to save lives?
