When you say meat, I think you mean the protein content, which is much higher in cat food than in dog food. "Meat" can mean lots of things, including companion animal renderings. YUCK!

I often refer to this web site:

http://www.doberdogs.com/menu.html

It explains the meanings of the ingredients, which will apply to cat food as well as dog food. (I know, it gives dog food comparisons, not helpful in this case.)

You can also google
cat food comparison
for some good hits.
