Cool pics...I've never seen them sit for a pic like that.
They are far ranging in the US: we have them frequently
around our Mtn house in NC. And, of course they are
common, but seldom seen, here in the FL 'burbs.

Your cat was doing the right thing; ours are very afraid
of them also. The Bob cat can put a hurt on cats and
very small dogs. It is absolutely no threat to your kids.
I wouldn't shoot it...
