On a somewhat related note, one of the cancer hospices in my town keeps a cat in-house. According to the nurses, when the cat camps in a particular patient's room it means the patient isn't going to live through the night. The cat only seems to do this with patients who don't have any family around to visit them. The nurses think the cat can somehow sense incipient death, and goes to keep the dying person company.
Or maybe it's a case of feline Munchausen by Proxy?
