We have an orchard that we want to keep the grass and weeds down in. We are contemplating fencing it with tight wire down low and letting guinea pigs mow it for us. We wouldn't be able to lock them up each night as we live about 3kms away but would have a water source for them and little hidey holes for them to live in. Does this sound ridiculous? I guess my concerns are that they would attract snakes and foxes and that they would breed like rabbits and I would go down in history as the people who "introduced" guinea pigs as a feral species!!! Thoughts??
