My father in law swears his cat knew he had lung cancer long before he did. She was always a loner type, never wanted to be petted or anything. Well, a while before he ever found out about the cancer she started sitting on his chest every night as he watched tv. I remember him talking about how concerned his cat seemed, always following him around and looking at him differently than before. When he found out, he said it seemed eery to him how the cat had been acting.
Maybe there is something to it. ?
