Bruno has had lots of experience with experimental animals & researching
feeding of experimental & captive animals world-wide.  I think when I asked
him the Pottenger cat question, he told me that cat chow manufacturers (&
rat-chow & dog-chow, etc.) are not stupid.  They're VERY careful about the
temperatures they use & the glop is not really "cooked" at temperatures
usually used by humans.  Dunno how valid this point is.
