My bunnies live in a dog kennel and run, there is strong wood on the roof and three sides, part of the front is very strong galvanised mesh and it has two doors with bolts. I saw a fox on top of the roof last week and immediately brought the bunnies inside in a panic, but I think they prefer being outside so I am thinking about putting them back outside with extra security measures (foxwatch sonic detectors and putting strong mesh puppy pen panels around the outside for extra strength with tarpaulin to cover it so the bunnies can't see out at nighttime). Has anybody who has their bunnies in housing like mine seen foxes around it and have they ever managed to cause any damage to it?
