Brief article (below) asserting that, unlike the case with dogs, there is no evidence that cats have an ability to smell or otherwise detect cancer in humans, despite the claims of some to the contrary.
The author is responding to claims he had seen from people who were insisting that their cats had somehow played a role in the detection of cancers which the people were ultimately found to have had.
Some people were saying that their cats had been sniffing around them oddly, pawing parts of their owners' bodies where tumors were later detected, etc.
Nonsense, says the author, who points out that misinterpretation of feline behavior, along with other more plausible explanations, are far better ways to explain what was really happening.
So while, as the author acknowledges, there does appear to be some evidence that dogs can use their noses to detect cancer in us, if your cat Missy is sniffing around you, she's much more likely picking up the odor of the ham sandwich you had for lunch.
But kind of a fun read for a Friday:
