I don't know about the excessive protein. I feed my cats and my Yorkie a prepared raw food diet that is essentially all meat. The kind I buy has ground bone in it too, but is mostly muscle and organ meat. HUMANS can have kidney problems from too much protein. Kidney stones are so common with people on high protein low carb diets that doctors call then Adkins stones. But the digestive systems of dogs and people are very different.
I agree that she made the comments she did so she didn't look bad.
