I don't think clean, unsalted (or at least very lightly salted) meat, without much for chemicals can be bad for a cat. I've given it to cats my whole life, and I've pretty much adopted my mothers feeding strategy, and almost every cat either of us has ever cared for has lived to at least 14 years, a few over 20. I do go light on any dairy products, as too much seems to give some cats diarrhea. And I try to avoid odd human foods, junk foods, etc... Cats digestive systems and organs aren't really designed to handle processed grains, sugars, and the like. Allot of that can cause renal failure in most carnivorous animals, as the kidneys aren't designed to remove glucose from the blood.
