  Part of me thinks this fox is curious.  Part of me thinks it's interested in food.
 Problems with cats = problems with dogs in this context I think ... since they are similar in size.
 
 In the back of my head, I want to say to bring food so if the fox makes a move, you can deter it with what it is seeking, food.  However, if you have food, that will also attract them, and possibly make them less on-guard about even coming up to you.
 
 DON'T BRING FOOD!
 
 Perhaps use some type of whistle or horn to try and scare it away?
