First thing is that carbohydrates are derived from a starch source such as rice( a grain) or potato(not a grain). Both supply carbohydrates.
So, if we take Momentum to figure out the carbs;
100-water(10%)-protein(35%)-fat(25%)-fiber(3%)-ash(6%)=approx 21% carbs.
Kinesis Grain free; 100-10-32-18-4.5-6.9=29.6%
All of the numbers are on the website and I list ash so we have accuracy versus a guess. Many would assume 10% ash if nothing is listed.
Also, my sales force is just myself. I don't remember being in Canada at all for years since we moved our production back to the States. Ohio Pet has only one sales guy, too.
