I'm bored today, and came across a thread on another forum about this food: http://drtims.com/ It seems pretty decent from my skimming through the website. Wilson eats almost all kibble now, minus a couple days a week where he gets a turkey neck or chicken quarter for the teeth cleaning benefits. He just never did that great on raw, was always puking; actually, yesterday AM he got a turkey neck, kibble for dinner, and this AM I got to clean up 2 piles of bile/bone puke. So anyway, I've had him on a few different brands and he does fine on all of them. I'm always looking for other stuff to try because I do like rotating foods. The Momentum formula at 588 cal/cup is tempting for me, although it's not grain free. You can get it in 44lb. bags though, which is also nice. Just wanted to see if anyone had ever heard of it, or fed it!
