Pro Plan is a great food. There are a lot of great foods. There are also people who will say its full of fillers and crap ingredients but the fact is that Purina has been around for a long time, employs veterinary nutritionists, and conducts feeding trials to prove the safety and balance of their diets. Only a few companies actually do that, the others being Royal Canin, Eukanuba, and Hills. While I do feed Victor, I also will throw in some RC and Euk. Most foods out there arent formulated by veterinary nutritionists and have zero feeding trials proving their safety.
