Here is an analysis of feral cat diets. http://www.ncbi.nlm.nih.gov/pubmed/22005434 It included 27 studies of only feral domestic cat diets (scat and stomach content analyses), 6,666 data points, and studies where cats had access to more than 5% of a diet from human sources were excluded.
On a DMB basis, the diet was 62.7% protein, 22.8% fat, 11.8% ash, and 2.8% carbs (all "incidental" from stomach contents). The omega 6: omega 3 ratio was 2:1, and the calciumhosphorus ratio was 1.5:1. Most raw food diets target a Ca ratio of 1.2 or 1:1:1. The theory is that the bioavailability of minerals from bones is less than in supplements added to foods. Oh - and the omega 6: omega 3 ratio of most commercial canned/kibble is 17:1
