(I put both lists in ascending values)
This is great information. I tried to get this from Purina. I
gave up after getting three different values for the same
product. It's very uneven the quality of information. It's much
better if this is published. It's kind of sad that this ordinary
information is only available as a veterinary resource. Why not
public information? After all, it's only the product listing.

Actually I doubt the information is all that good. Unless you can
match the analyticals to the same manufacturing location and the
same lot of pet food. Any expectation that nutrient values in
grocery store foods will be the same from one lot to another is
pretty much wishful thinking. That is not the goal - or even a
last place sub-goal of foods manufactured for this market channel.
It shouldn't be at all surprising that you would get three or four
or different sets of values. It would not surprise me at all to
find an analysis of 3 different lots of precisely the same food
that have a variation in nutrients by more than 50% from the
highest to the lowest.

If you have any citations for that, I would like to see them.
