I heard about this,it really is unbelievable-you just can't imagine how terrifying that must have been for the girls,and the parents for that matter.
Thankfully there aren't that many foxes around our area,but where we used to live,there were a few,they are so street savvy and no way afraid of human contact,they used to try and get to my rabbits every other night,even though we had a dog that would give chase! I read somewhere that foxes don't come near if you have a dog,this isn't true!!!! My dog was huge,the foxes weren't bothered in the least by him!!!!
They are beautiful to watch,but not that close! Hope the girls recover quickly.
