This was one remedy I found online and considered trying, as the soiled litterbox contents would be placed in the burrow and not where the dogs could get at it. (Another suggestion was ammonia-soaked rags in the burrow, but that is not an option for me.)

Someone asked how large my dogs are. We have two Collies and two Boxers. The Collies would probably want to be friends with the intruder, as they are very friendly with other animals. (I found my male last year gently kissing a field mouse in the back yard. The poor thing was wet from being licked-and trying desperately to escape by climbing the 6 foot stockade fence.)

The Boxers-on the other hand-would be likely to go after it aggressively if it showed up at the wrong time.
