I would like to know the best food to give my cat to maintain a healthy uninary tract. He has had some problems and the vet wants me to change his diet. The problem is I get all different opinions as to what is the proper food. Everbody tells me their food is the best and the other guys is not really any good. I know I need a food that will maintain the proper PH balance. What brand and variety of food is best to give my male cat that will meet all his nutritional needs. If you have any suggestions for both wet and dry food I would appreciate it. Thanks Jeff Martin
