B re-read this paragraph:
"The Pottenger's Cats study was done by Dr. Francis Pottenger between 1932 and 1942 using about 900 cats. The study itself was conducted together with Dr. Alvin Foord who was a professor of pathology at the University of Southern California. It was a study that was done under very specific scientific conditions with a very actuate record keeping, observation, and statistical analysis. In fact, all the 600 cats had complete medical histories even before the experiment began."
Were they using 900 or 600 cats?
What exactly are "very specific scientific conditions?"
