OMG thats so awful, I bet it was very scary too! since I live in NE also, although I'm not a native New Englander. I moved here from Ca I had never heard of such an animal before moving here, and was warned by neighbors about thoes nasty mean Fisher cats.. because they have a very bad tempers. and are extrememly vicious will attack and are relentless in stopping. usually they attack pets more then humans, but I think the one you incountered was coming after you too.. Like you said good thing you had on those DR Marten shoes is Right!! Plus Brave little Mabel lovicon was such a brave girl protecting you. And you her, Just another wonderful thing to add to the list of Many on how great Our Boxers truly are.
I'm so sorry that you and Mabel had to go through that horrible experience.
Sending you a (((( big hug))))) Lots and Lots of(((( Healing Vibes)))) for your Brave Mabel Keep us posted on how she is doing.. Vickie
