"My cat has been eating Purina Pro Plan (chicken, chicken & liver, turkey & giblets, turkey & rice) for 4 years with no health problems, not even urping. Her first year of life she had a few bouts of cystitis which (my vet suggested) was caused by sub-par food that did not have enough pure protein. She told me to shop for quality wet food and to make sure that in the first 3 ingredients, at least one was pure chicken or turkey or beef, and to stay away from seafood. Once I switched her to Pro Plan, she never had another bout of cystitis. This was also true with dry food -- first 3 ingredients MUST include pure chicken (NOT corn meal, barley, soy, chicken fat!). The closer REAL chicken or turkey is to the very FIRST ingredient, the better the food for her. Pro Plan is a keeper !"
