Bless your heart ... you had them all spayed/ neutered? Are they friendly enough to be petted, and possibly adopted into homes, or are they really feral? If they are tamable, maybe you could place an ad in the paper for adoptive homes ... if they are really feral, maybe you could find an organization that could help you relocate them to another place? I'm not much help here I know... best of luck, and hats off to you for your efforts...whatever the outcome!
