He had only been in there for about six hours, so it was about seven in the morning. Wolves are nocturnal so he felt tired, as he usually went to sleep right now. He looked around, still in his wolf form, and decided the first cave he found, he would claim. Within the next forty minutes, he had found a cave, and proceeded to urinate around it. He was exhausted, too much so to even check the scents in the area. He goes into the cave to go to sleep, not knowing what tomorrow would hold, and for the first time in his carefully laid-out life, he didn't care. 

If he got killed tommorow, or tonight, no one would know, or care, for that matter.
