You might also consider getting him a drinking fountain. A cat who drinks lots of water washes out the minerals before they get to form crystals, no matter what kind of crystals they were!

He still likes his kibble (Hill's C/D) best, but he gets a little bit of "treat food" twice a day so I can put his medicine in it. (His crystals were struvite, so I use a low-magnesium food to mix his allergy stuff and vitamins into.) Southern Agriculture and Pet Food Direct carry a lot of specialty foods - they're worth checking.
We actually do have a "drinking fountain" for the cats- one of those self-filtering water bowls. They love it! And their other drinking fountain is the bathroom sink.

I'll have to check into the food when our supply starts getting low, although the vet said we'd only have to have Stewie on the special diet for a month. I'm hoping the bag and cans we bought will last that long!
