Mine all eat Royal Canin lite formula with the hair and skin formula as treats.

I too have HUGE problems with Science Diet for many many reason. I cringe whenever I see someone is feeding it. And of course vets don't have a problem with it. I wouldn't either if I got a cut back from the company for selling it. I have heard they are coming out with a more natural formula. *shrug* But then I haven't looked at the ingredients for several years either. *shrugging again*
