Even if you get one of the canned foods that are 90-100% meat, their protein percentages are nowhere near what the dried foods have become. Every all-meat canned food I've seen was somewhere like 10-15% protein depending on type of meat--the same protein levels of raw meats. I know that despite my dogs being fed 80-85% ground, raw meat, organs & bone every day, they're not getting 80-85% protein--it's more comparable to canned foods depending on the meat fed that day. Compare any brand's canned protein percentages with the same brand's dry protein percentages--when the same type of meats are used--and you'll see what I mean.
But you can't make comparisons like that. The protein on the can
seems lower, because of the moisture content. When comparing protein levels (or any nutrient for that matter) you have to do a dry matter conversion.
Find the moisture content of the food (78%, for example) and subtract from 100%. (22)
Divide the protein percentage by the dry matter percentage. Say the can reads `10% protein
.10 divided by .22 = .45 or 45% protein
If this is a food with no fruits veggies and grains, hopefully the cat is managing to use most of that 45 %
Then take a "high protein low carb" kibble such as Evo with 50 % protein and 10 % moisture
.50 divided by .90 = 55% protein.
However, Evo is KIBBLE, and while it is grain free and low carb, it is still only 10% moisture and all of us here know that a cat can never ever make up for the lack of moisture in dry food regardless of "quality" of the kibble. (and some of that protein in the Evo is lost to the cat, it coming from
peas and
pea fiber)
