I am always a little surprised, and saddened, by people who are so set in their opinion that they refuse to even look at new information that could challenge their views.
Frankly, I don't get it. What's to "believe in"? This isn't about Santa Claus. There are studies--many studies--that support what I've said about nutrition. One of my more complete articles is offered for sale on our website, called "What Cats Should Eat." It's extensively referenced. I'd be happy to send you a copy--free--*IF* you can honestly tell me you'll read it with an open mind.
Ultimately, all I can do is offer the articles I mentioned, you can read them or not. You can "believe" them or not. You can feed what you want. But, I suggest that you get yourself educated about *all* the facts before you make your decision. You are not serving the best interest of your cats when you refuse to even consider that things just might have, possibly, maybe, could be, changed, and that what you have done before (based on the best knowledge available at the time) may *not* be the right thing to do now, based upon what we know now.
Cheers,
