Yes, Are there any rescue organizations in your area that you can contact, besides the SPCA, that work with ferals? They trap, neuter, find homes for thse that are adoptible and release those that are not. Feeding cats will only bring more cats, and I concider myself lucky that no strays come here because I would not be able to let them starve either. What, besides "don't feed them" DOES the SPCA say???
