Hypo-Allergenic Cats

I was reading about "Hypo-Allergenic Cats" at slashdot, which led me to the website http://www.allerca.com/. I found the cat facts really interesting until I hit this fact under the heading "Cats and People". It said, "It has been proven that stroking a cat can lower one's blood pressure" ....disgusting! I don't know who tried it and proved such a disgusting thing. Really pitty the cat :-)
