Yeah this one looked really sick. It was sad. What did you feed him? The first time I saw the fox it made a sound that almost sounded like a cat. I wasn't sure if it was a huge stray cat or a small mountain lion.
I feed them dry dog food, chicken bones, lunch eat ends a local deli saves for me super cheap and bread ends! They do sound like cats when they cry, Siamese actually. Here is a pic of Mr. Bones, the only one who shows up in daylight.
