I've removed more than a dozen of the things . The pound around here won't take feral cats . If you trap them - take them somwhere with a large coyote population . But if I were you ,, I'd go cat hunt'n . Take your live traps and set them somwhere with alot of rabbits . Bring them to your property ,,, and leave them alone for at least 8 months . They should repopulate the place in no time .
