the reason i cant fence off an area as it is our house paddock that is 5 acres, which is full of driveways, sheds, garden beds, a pool, its kind of hard to explain. When no one is home he is tied to an old flying fox about 100m long, so he can run up and down. I think my only option is to make sure i'm watching when he is running free. But again, thanks for the replies. And he did get bitten by a snake about 2 weeks ago, but we mate it to the vet just in time
