I was watching one today, I called it in, it climbed up some mesh and under a rabbit snare I had out, I'll put some photos on later, when I'm back in...
Yes they will do some damage, but thats the nature of the beast... for the majority of people they are not really a problem...if i had any problems i.e bird predation then that would be a different matter I must admit I love seeing them myself great little animals, I spooked one earlier that was just going in for the kill on a mixy rabbit, sure he will find it again... do them both a favour..
