We have unfewnced 2 acres , have never fenced garden and we are surrounded by woods and fields with lots of wild critters in the mix. We have never fenced our garden and have never had rabbits , coons or any other pest bother it. I make sure to walk our dogs around the perimeter of the property to do thier buisness and when I comb them i save the hair and spread it around the boundreis and around the garden. My husband saves his urine in a milk jug and pours it around the boundry too , I knoww ewwwww. But because we eat meat , wont work for vegitarians or vegans , it will keep most animals away because they sense pedator . Marking territory is a natural and safe way to protect to some extent , I know it will not work with the large predators or flying predators but it sure seems to have helped our little corner of the world.
