Shadow didn't start off as a bed buddy. But the homes here in South China do not have heat. So, the winter when the temperature gets to <15C, the concrete buildings get pretty chilly. Shadow discovered the bed was warmer than the tile floor. I had an electric blanket. Since then, he is my "guard" when I sleep. Consequently, I keep him free of parasites, frequent baths and grooming. I figure if we are going to share a bed, then we both need to be clean. Fortunately, he doesn't like to be covered and is happy on top.
