Trying again with a hopefully a clearer subject line. The following
page gives nutritional analysis numbers that I don't see elsewhere for
many canned foods. Based on these which ones do you find acceptable?

It really is based on your cats needs.  Every cat is different.  Start off
with the lowest carb count you are comfortable with (under 10 is best) and
go from there.  I am feeding Evo to one of mine at the moment.  it is high
in calories, so once my kitty has put on a bit more (recent weight loss) I
am probably going to switch again.

If you want the best food for your kitty, look into a raw diet.  You'll know
exactly what he is eating, and you won't have to worry about the fillers
that some companies use (garlic, tomatoes - from the nightshade family and
in excess are toxic to cats)   I know.. gross and icky, but surprisingly it
is a lot easier to do than I thought.
