Glad you have something working! My only complaint w/ the z/d is the consistancy. Takes her longer to get through the serving. She'll typically walk away but if we move the bowl back in front of her she starts eating again.
Leave her on the z/d if it's working. This stuff is probably better quality that anything you'd get in the frozen food aisle or a fast good chain. My wife has worked in a Vet Hospital for almost 15yrs and at one time managed the pharmacy. She believes in the Hills and Royal Canin lines...
