We just bought Eukanuba for the first time recently for our grandchildren (the cats), but they don't seem to like it as much as Purina. I'm from a very frugal family and buying animals, beloved as they are, expensive food is just difficult for me. My mom used to give her dog Brewer's Yeast which she said helped her coat. She mixed it in her food.
Eukanuba is too expensive for me too right now. Real Estate is not what is was a couple of years ago. LOL!
