We found this “sleeping” or sick in center of dirt forest road in sun. We thought it was dead at first, but when I tried to turn it over with a stick, it was alive. Was it hibernating? Was it sick? A disease that eats the brain out? Just guesses. We set salal branches all around it so we wouldn’t accidentally step on it on our return walk, but when we hiked back the mouse was gone! Had it only been “playing dead” while we were there and actually is healthy? We don’t know!
