Guys,
Fox may not be aggressive, but my son was driving down one of the main drags in Alva, Oklahoma, one night about midnight when he saw a red fox cross the road with a large house cat, complete with collar and bell, in his mouth. The cat was nearly as big as the Fox.

I 'coon hunted several years as a much younger person, and I've never heard about them carrying virus. And I've seen old hounds that had been bitten by 'coons so many times that you couldn't count the scars. Usually their ears were ripped up. But maybe the virus is something that I haven't heard about.
