Actually he looked in very good condition. Sleek, no mange. He was very alert and listened to the chickens before heading off into the woods. I hoped he would stop by the groundhog den but he didn’t.I'm not aware of Blossom noticing them.
Long ago there was some yowling and she became attentive and bristled. But that's the only event that comes to mind. I keep Blossom inside at night so she can't hunt native species. She can't come to harm from other cats at night.
I guess the fox is hungry at this time of year.
