Any opinion on this canned food for UTI prone cats? The ingredients don't look the best but the cats don't seem to like the Nutro Max too much. They tolerated Hills c/d for a couple months but I wanted something non-prescription and a bit less expensive. Any more recommendations? I haven't tried Pro Pac yet (thanks for the tip, Sharky) but I wanted more options. I was really hoping they'd like the Nutro since they LOVE the dry. Thanks!
