Yes it does, and without the % water, the other numbers mean nothing.
You divide the % of protein and fat by the % of non-water to get a standard
dry value. Thus in kibble with 10% moisture, something that is 36% protein
would be 36/90 = 40% protein. If the fat is 22%, that translates to 22/90 =
24% of dry weight. A canned food such as Iams kitten is about 14.5% protein
with 68% moisture (if I'm remembering correctly--don't have can in front of
me), so that's 14.5/32 = 45% protein.
So if you know how much moisture is in the mouse, you can get comparison
numbers. Now at http://www.holisticat.com/rodent_arch1.html which you
mention, it says (about 3/4 down the page) mice are "62.02% water, 18.99%
protein (or 50% dry matter basis), 10.46% fat (27.34)". So mice are indeed
higher in protein and fat than Totally Ferret.
