LOL, I hear you! But listen to this: my mom and dad were visiting my sister a few weeks ago and even though their pets (cat and dog) had never paid much attention to my mom, during this visit they never left her alone. They sat on her lap, circled her feet, smelled her face, and watched her constantly (she wasn't feeling well, but chalked it up to the fatigue of travel). The day after they returned home, she collapsed and was hospitalized for a week. Don't tell me that pets can't tell when you're really sick.
Sometimes I think that a "Lab" report (from a real Lab!) and a "Cat" scan are some of the most valuable tools you can have in your diagnostic arsenal.

I have a friend whose cat woke her up in the middle of the night by repeatedly running and jumping on her. Once awake, the cat ran back and forth between the bed and the hallway. When my friend got to the hallway, the cat ran back and forth down the stairs. My friend followed him downstairs and noticed an odd orangish light in her dining room. It was the start of an electrical fire in the ceiling.
She managed to get it put out. If not for the cat's insistence my friend probably would have lost the house, her mom, their 2 dogs, both cats and her own life.
Now if the cat had only called it in on cell phone... ;-)
There is a very good theory that pets (especially dogs) can smell cancer cells. There is a lot of research right now taking place around that theory. I have a sneaky suspicion that the theory will be proven to be fact.
The way that dogs and cats have evolved to become pets, satisfying humans, I would have no doubt that they can sense illnesses in humans.
