A fox family has dug its den under the cement slab of my detached garage. I only see one hole, it's in back. I was not initially fearful; figured I leave them alone, they'll leave me alone. Two nights ago, very late, moonless and very dark, I was going quietly from house to garage when I heard (too dark to see) what I assume was a fox parent "huffing" at me from the direction of the side of the garage. I understand that he/she feels protective of its kits, and I was too wary to continue forward to the garage, for fear of provoking it. I quietly returned to house instead. Would a fox actually attack if it felt its kits were being threatened? How shall I behave in this type of situation? (My neighbor's bedroom windows are very near the property line, would want to avoid being too noisy at 1:00 a.m.!) I am happy to share my property with wildlife, but I need to safely move between my house and my garage. Also, when I mow lawn, need to remove gutter extenders, one of which is inches from den opening. Is it risky to go that close at this time? Thanks for your help.
