Hi-
In my opinion, catinfo dot org is a great site that addresses this issue. The most important thing you can do for this is to add as much moisture to the cats diet as possible. I give my 4 cats about 3 oz of canned food each everyday. Along with that, I feed a little bit of Wellness core, Earthborn Primitive or Taste of the wild dry food. The author of the site mentioned above does not recommend any dry food at all to maintain urinary health, however. but, that gets pretty expensive. Good luck, I know they can be picky.
