Burrowing animals like porcupines, diggers like jackals, and small antelope such as steenbok can create ongoing problems by forcing their way through and underneath fences, leaving holes that require constant repairs to keep your livestock secure. One way to reduce this workload is to give these animals a permanent passage. Many will quickly adapt and consistently use the designated route rather than creating a new hole each night. Having animals funnel through the same points also makes it easier to monitor their movements using cameras or tracking their spoor.
