Used to be excellent...what’s changed?
My cat was on this food for 13 years, it kept his skin & stools under control. Since November 2018 he started with runny stools, vomiting & weight loss. As soon as I switched him to hills d/d everything improved until this week, he’s started vomiting with runny stools again, I’ve checked the bag of food and there’s been another formula change from venison to duck! I wish hills would stop changing the formulas of products that used to work very well but are now making my cat sick.
